Karimi M. Hassanpour Asil H. Samizadeh Lahiji S. Talesh Sasani   Experiments were conducted to study the effects of temperature and chemical treatments on the vase life of cut Asiatic hybrid lily cultivar Pisa, with sixteen chemical treatments using factorial design with 3 replication arrangements. Lilium cut flowers were harvested when the first flower colored fully. Following chemical treatments, they were grouped in different combinations before storage. The treatments included sucrose, 8- hydroxy quinoline sulfate (HQS), citric acid (CA), gibberellic acid (GA3), kinetine (KI) and distilled water as control. Lilium cut flowers were pulsed for 24 hours in different solutions, then brought out and kept in the distilled water at temperatures of 4°C and 22 ° C .Effects of applied treatments were evaluated on different characteristics like vase life, the amount of water absorbed, flower diameter, total soluble solids and fresh weight. Results showed that the temperature of 4°C had the most effect on vase life, keeping the quality of lilium cut flowers. The results also displayed that the chemical treatments kinetine + sucrose had the most effect on vase life and percentage of sucrose, gibberellic acid + kinetine delayed yellowing of the foliage, 8- hydroxy quinoline absorbed the most amount of water, and treatments sucrose + kinetine , gibberellic acid + 8- hydroxy quinoline sulfate and gibberellic acid + citric acid were most effective in increasing the flowers diameter.

Raei M. Sedghi R. Seied Sharifi   A factorial experiment, based on RCB design, with three replications was conducted to evaluate the effects of rhizobial inoculation, urea, and weeds on soybean performance in the field. The factors under study consisted of inoculation and non-inoculation, three levels of 0, 150, and 300 kg/ha urea, and weed-control and weed-infestation. Results showed that weed-control, inoculation and urea application increased biological and seed yield. The highest effect on yield was due to weed control, followed by inoculation and urea application. Inoculation, weed-control and urea application of 300 kg/ha enhanced protein percentage in soybean grains. In this case, inoculation had the highest effect on protein percentage, followed by urea application and weed control. In contrast, only weed-control significantly increased seed oil percentage. Seed filling rate increased as a result of inoculation, but, seed filling duration was not affected by inoculation. Weed-control improved seed filling rate and duration. Urea application induced seed filling duration, but had not any effect on seed filling rate. Soybean Yield Seed filling rate Protein 2008 4 01 8 91 http://jcpp.iut.ac.ir/article-1-823-en.pdf

O. Karami A. Deljou A. Mahmoudi Pour In vitro regeneration of two cultivars of carnation, namely, ‘Nelson’ and ‘Impulse’ was studied through direct somatic embryogenesis. Somatic embryos were formed directly on petal explants cultured on Murashige and Skoog (MS) medium containing different concentrations (0.2, 0.5, 1, 2, 4, 6 mg 1-1) of picloram. Maximum embryogenesis was obtained with 1 and 2 mg/l picloram. Globular shaped embryos were developed into cotyledonary-shaped embryos when they were transferred to the growth regulator-free media containing different concentrations (2, 4, 6, 8, and 10 %) of sucrose. Increasing sucrose concentrations in the culture media enhanced somatic embryos development. Cotyledonary somatic embryos developed plantlets when they were transferred to the half-strength MS culture medium containing 3% sucrose. Plantlets also continued to grow under greenhouse conditions.

O. Khademi Y. Moustofi Z. Zamani M.R. Fatahi Moghaddam In this experiment the response of persimmon fruit, cv. Karaj, to astringency removal by ethanol and the effects of this treatment on some important fruit characteristics were investigated. Fruits were harvested at three different dates and at each date based on the previous results, and then modified treatments were applied. The best ethanol astringency removal treatment in this study was 10 ml of 38% ethanol per kg fruit for 48 hours. The period after ethanol treatments had no effect on the reduction of soluble tannin concentration, although it resulted in the reduction of flesh firmness and increased soluble pectin. Ethanol treatments and also temperature conditions reduced flesh firmness and increased ground color of fruits however, the effect of ethanol treatments was more than temperature conditions. Temperature conditions increased ethylene production, thus reducing the flesh firmness and increasing the ground color index of fruits. Ethanol treatments did not increase the ethylene production, and it seems that its effects on some characteristics are due to ethanol itself or factors other than ethylene.

Mohammadi Mohammadabadi S.J. Hosseinifard N. Sedaghati   Effect of change from the conventional (flooding) to subsurface irrigation system was studied on mature pistachio trees (Cultivar Ohadi) in Kerman pistachio research station for four years. This experiment was carried out in a randomized complete block design including 7 treatments and 3 replications. The experiment also used two irrigation intervals (7;14 days) and three water rates according to pan coefficient (20%, 40%; 60% evaporation from surface of class A pan) for subsurface irrigation system with 6 treatments the conventional (flooding) irrigation system was tested as control. The pipes of subsurface irrigation system were installed at 90cm distance from trees trunk at each side of trees, and 50cm from soil surface. Mean of pressure and discharge in the pipes was 0.8 to 1 atmosphere and 5.4 Lh-1m-1, respectively. Different factors of quantity and quality pistachio yield, current vegetative growth, water use efficiency and soil electrical conductivity were measured. The results showed that change of conventional (flooding) to subsurface irrigation system is possible and the best treatment can have water rate of 7174 m3ha-1y-1 with 14 days irrigation interval. In comparison with other treatments, this treatment has better quantity and quality pistachio yield. Water use efficiency (WUE) of this treatment was 164g dry yield per cubic meter. Nevertheless, application of water rate of 4783 m3ha-1y-1 can result in the deficiency of irrigation water. At this water rate, WUE was 177g dry yield per cubic meter. However, it was found that the application of lower water rate (<4783 m3ha-1y-1) produced severe effects on the treated pistachio trees, e.g. decreasing the growth rate, yield and increasing the early splitting in pistachio fruits. Finally, it is concluded that 14-day interval irrigation is the preferred treatment for pistachio trees. Also, soil salinity showed considerable change in subsurface irrigation treatments after irrigation system was changed, especially in the first year.

Hojat Ansari M. Hasanpour Asil A. Hatamzadeh B. Rabiei S.H. Roofigari haghighat Variations in theaflavin and thearubigin content during fermentation and the effects of these variations on brightness and total color in black tea were evaluated at the Tea Research Center in Lahijan in the year 2004.  Percentages of theaflavin (TF), thearubigin (TR), total color and brightness were determined in two clones 100 and in the natural Chinese hybrid during flushing in the months of June, August and October and different fermentation time (30, 60, 90, 120 and 150 minutes). It is evident from the results obtained that apart from genetic differences in the clones under study, changes in climatic conditions during different periods of flushing and fermentation time can to a great extent influence the amount of TF, TR, total color and brightness in black tea. Results obtained also indicated significant interacting effects of clones, different flushing and fermentation times on the quality-determining characteristics of black tea. No significant correlations were found between TR and brightness however, significant correlations were found between other characteristics studied at the 1% probability level. On the basis of regression analysis with fermentation time (independent variable) and each of the characteristics studied (dependent variable), linear relationships were detected between fermentation time and brightness and TF content. Multi-variable regression analysis between brightness (dependent variable) and TF and TR (independent variables) showed that more than 56% of variations in brightness in black tea was related to TF and TR. Also multi-variable regression analysis between total color (dependent variable) and TF and TR (independent variable) indicated that more than 43% of variations in total color in black tea can be attributed to TF and TR percentages Black tea Fermentation time Theaflvin Thearubigin Brightness Total color 2008 4 01 47 55 http://jcpp.iut.ac.ir/article-1-820-en.pdf

Baghizadeh A. Talei M.R. Naghavi M. Haji Rezaei In order to estimate the number and inheritance of controlling genes for grain yield and some of the related traits in barley, Afzal and Radical varieties along with their F1, F2 and F3 generations were planted in a randomized complete block design with three replications. Head weight, head length, number of heads, number of spikelets, awn length, hundred grain weight, grains per head, straw yield per head , harvest index and grain yield in different generations were recorded. Analysis of variance indicated that mean squares of generations were statistically significant for all the traits. Then, generation mean analysis was performed for all the traits. Based on the results, additive and dominance effects played roles in controlling awn length. For the other traits besides the aforesaid effects, epistasis effect was also significant. Also, results indicated that dominance variance had the most important role in controlling the inheritance for traits. The average broad sense heritability for all the traits was estimated between %69 - %89. The number of genes for all traits was estimated to be between one and six.

Shamseddin H. Farahbakhsh To study the effect of salt stress on quantitative and qualitative parameters of canola (Brassica napuse. L) cultivars, and determine the possible mechanisms of salt tolerance and the best salt tolerance indices, an experiment was conducted under a rain-shelter at experimental field of university of Kerman in 2004. The experimental design was a complete randomized block (RCOD) with four replications. Treatments consisted of all combinations of different levels of three factors including variety (Kobra×Regent, Ceres and Okapi), salt types (NaCl and CaCl2) and electrical conductivity of saline solution (0, 4, 8 and 12 dS/m). All treatments were randomly distributed in each replication. Results of the analysis of variance showed that grain yield, yield components, oil and protein contents were significantly affected by salinity (P< 0.001). All the mentioned traits reduced with increasing salinity. It was also found that there were significant differences among genotypes for the mentioned traits. Cultivar of Kobra×Regent showed the highest values of the above traits except for the oil content. Proline, protein and sugar contents were also affected significantly by salinity (P<0.001). The highest and lowest sugar concentrations and protein contents were recorded for control and 12dS/m treatments, respectively. Proline content showed a reverse response and increased with increasing salinity. Mean productivity (MP), geometric mean productivity (GMP) and stress tolerance index (STI) are suggested to be the most suitable indices in order to select genotypes of high productivity under both stress and normal conditions. Based on these results, Kobra*Regent was selected as the most tolerant cultivar.

Karimizadeh M. Safikhani Nasimi M. Mohammadi F. Seyyedi A.A. Mahmoodi B. Rostami One of the applications of Non-Parametric methods is determination of genotypes rank in different environments, which is also used as a measuring stability. A stable genotype shows similar ranks across different environments and has minimum rank variance in different environments. Non-Parametric Stability Statistics require no statistical assumptions about the distribution of the phenotypic values and are easy to use. This study was carried out to determine the ranks of 10 Lentil genotypes (Lens culinaris Medikus) across ten environments in 2002-2004, using a randomized complete block design with four replications. Analysis of Thennarasu non-parametric statistics showed that genotypes 8 and 9 had high stability by NP(1) statistic and genotypes 9, 8 and 1 had stable yield in NP(2) method. Result of the NP(3) statistic was similar to NP(1) statistic. NP(4) statistic selected genotypes 9 and 1 as the most stable genotypes and ultimately NP(5) statistic introduced 9 and 1 genotypes as stable genotypes in this experiment. Also analysis of Nassar and Huhn non-parametric statistics revealed that genotypes 1 and 2 were most stable and well adapted across ten environments. In addition, it was concluded that plots obtained by both mean yield (kg ha-1) vs.Si(1) and mean yield (kg ha-1) vs. Si(2) values could enhance visual efficiency of selection based on genotype × environment interaction. According to these configurations, genotypes in section 1 can be considered as stable and well adapted to all environments, having general adaptable ability. For recognition a daptability,Si(1) and  Si(2) take preferred over other non-parametric statistics.

Seifi N.A. Babaeian Jelodar A.M. Shakib Sorrel (Rumex acetosa L.) is a model dioecious plant in genetic and molecular studies for sex determination. In this research, gus reporter gene transformation to leaf disks of this plant via Agrobacterium tumefaciens was evaluated based on transient expression of this gene. Three strains of Agrobacterium( LBA4404, C58 and EHA101) and two kinds of bacterial suspensions (suspension I: Agrobacterium cells were grown in LB medium with PH 7 and suspension II: the cells were resuspended in MS medium containing 100 mM acetosyringone with PH 5.2) were analyzed in a factorial experiment with 3 replications in Complete Randomized Design (CRD). Also, the effects of three different times of pre-culture of explants (0, 2 and 4 days) were examined. Results showed no significant difference among bacterial strains, whereas suspension I and explants without pre-culture had higher efficiency in gene transformation to this plant. Based on the best treatment, stable transformation with different days of cocultivation was carried out and revealed that the 4-day cocultivation is more efficient than the 2-day cocultivation in gene transformation to Sorrel. The histochemical GUS assay and PCR analysis were done on putative transgenic plants. Results showed that some of these plants contain at least one copy of the transferred gene or genes in comparison with control plants . <i> Rumex acetosa</i> Dioecious Transformation <i>gus</i>gene Transient expression Stable expression 2008 4 01 117 126 http://jcpp.iut.ac.ir/article-1-826-en.pdf

Rahimi B. Rabiei H. Samizadeh Lahiji A. Kafi Ghasemi Six rice cultivars were crossed in half diallel design to evaluate their GCA and SCA in 2005. In the following year, parents and their progenies were grown in a randomized complete block design with three replications, and 10 traits were measured. The analysis of variance showed significant differences (p≤0.01) between cultivars. Furthermore, general combining ability (GCA) and specific combining ability (SCA) for parents and hybrids were significant. Therefore, additive and non-additive gene effects on controlling traits were demonstrated. According to the analysis based on the second and fourth Griffing methods, additive gene effects were more than non-additive gene effects on controlling growth period, plant height, panicle length, number of panicles/plant and brown rice length, while other studied traits were more controlled by non-additive gene effects. Comparison of the second and fourth Griffing methods showed that the proportions of additive and non-additive variances in two methods were different. Moreover, GCA and SCA resulting from the two methods for several traits such as vegetative and productive growth period, plant height, number of filled grains/panicle and grain yield were significant. Therefore, it could be concluded that using parental generations in the second Griffing method may cause biased estimate of the GCA and SCA variances. Thus, using the fourth Griffing method is more suitable than the other methods in providing time, cost and facilities, and is recommended as an applicable method.

Tousi Mojarrad M.R. Ghannadha In order to study inheritance of traits (Height, Peduncle length, Extrusion peduncle length, Diameter first internode, Diameter secondary internode, Diameter third internode length of secondary internode, length of third internode) associated with height in bread wheat, seven cultivars of bread wheat with their F1 progenies produced through a half diallel mating design were planted in a randomized complete block design with 3 replications in normal and drought conditions in the Seed and Plant Improvement Institute, Karaj, in 2004. Analysis of variance showed significant differences for all the traits in normal and drought conditions at 1 % probability level. Diallel analysis showed that general combining abilities were significant for all the traits in normal and drought conditions at 1% level of probability. The specific combining abilities were not significant except for extrusion peduncle length and length of secondary internode. Additive effect was more important in controlling all the traits. Height had the most broad sense and narrow sense heritabilities in normal and drought conditions. It was also found that increasing all the traits except for plant height and length of the third internode was controlled by the dominance alleles in normal and drought condition. The analysis of traits revealed more mean traits in progenies compared to parents in both normal and drought conditions. Sardary and Roshan varities showed the best general combining ability in normal and drought conditions.

Sahebani J. Zad A. Sharifi-Tehrani A. Kheiri Polyphenol oxidase (PPO) activities were measured spectrophotometrically in tomato(Roma VF: resistant to Fusarium oxysporum f.sp. lycopersici and susceptible to Meloidogyne javanica) roots inoculated with nematode and fungi in four biological life stages of nematode. PPO specific activity showed a significant decrease in treatments (nematode + fungi) as compared with control plants. Results showed that nematode is able to change or suppress induction of this enzyme in spite of fungal induction. Nematode in all biological stages suppressed the induction of PPO activity in tomato roots but in young adult formation stage the suppression was higher than other life stages including giant cell formation, egg-laying and penetration. Native polyacrylamide gel revealed the presence of five isozymes of PPO with Rm values of 0.26, 0.31, 0.44, 0.50 and 0.63. Isoforms with Rm values of 0.26, 0.44, 0.50 and 0.53 showed significant changes in nematode + fungus inoculated tomato plants compared to plants inoculated with fungus alone. Based on the results obtained in this study, nematode infection resulted in suppression of tomato defenses against the fungi (as secondary pathogen) and intensified the fungal disease. Five PPO isoforms with Rm values of 0.26, 0.31, 0.44, 0.50 and 0.63 were shown in native polyacrylamide gel among which the isoform with Rm value of 0.31 had a thicker band in tomato plants inoculated with nematode or fungus alone. Two isoforms with Rm values of 0.44 and 0.53 in nematode-inoculated plants were similar to the corresponding bands in the healthy control. Isoforms with Rm values of 0.26, 0.44, 0.50 and 0.53 in nematode-fungus-inoculated tomato plants showed significant changes compared to plants inoculated with the fungus alone. Nematode infection of root tissue caused suppression of PPO specific activity and induced changes in PPO isoforms with Rm values of 0.26, 0.44, 0.50 and 0.63 more significantly than isoform 0.31. <i> Meloidogyne javanica </i> Polyphenol oxidase Nematode life stages <i> Fusarium oxysporum </i> f.sp.<i> lycopersici</i> Plant- pathogen interaction 2008 4 01 169 180 http://jcpp.iut.ac.ir/article-1-830-en.pdf

Azizi Regarding the public concerns about serious health risks from pesticide, the occurrences of 105 pesticide residues including Organochlorine, Organophosphorus, Organonitrogen, Dicarboximides, Strobilurin, Triazine, Pyrethroids were assessed using a descriptive method in 25 fresh and greenhouse vegetable samples (fresh carrot, greenhouse tomato and cucumber). Ethyl acetate was used for extraction of pesticides from samples and the extract was cleaned up by Envicarb Solid Phase Extraction column chromatography. Pesticide residues were identified and quantified using gas chromatography ion trap mass spectrometry detector. The mean recoveries and limit of detection of the pesticides in samples were respectively 61.67-117% and the reproducibility of relative standard deviation values for the pesticides was 3.49-14.55%. Our data demonstrated that 80% of the total analyzed samples contained detectable residues including trifluralin, permethrin, chlorpyrifos, fenvalerate, fenpropathrin and iprodione, which were below the accepted maximum residue limits (MRLS) adopted by FAO/WHO Codex Commision Alimentarius.

Safaee S.M. Okhovat G.H. Hedjaroude H. Younesi In order to diagnose form species of Bipolaris involving root and crown rot of wheat plants and determine their distribution, frequency and disease severity, 410 wheat fields (W. Fs.) in different regions of Kermanshah province were sampled at seedling, tillering and heading stages during three crop years (1997– 2000). Also 90 W. Fs. (30 per year) in different regions of the province were chosen randomly to estimate percentage of infected wheat plants. For the isolation of the fungi from tissues of root, subcrown internodes, crown and foot, the tissues were surface sterilized and placed on culture media. The results showed that there were some root and crown rots in the most regions of the province and the percentage of diseased plants was 0-24%, whose average was 3.2%. Forty three isolates belonging to form genus Bipolaris were isolated including form species B. sorokinina, B. cynodontis and B. spicifera. All three form species were pathogenic under greenhouse conditions. Disease severity and frequency of B. sorokinina were more than the others. Disease severity of B. cynodontis and B. spicifera was the same and their differences compared with the control were significant.

Sahebani N. Hadavi This research was conducted to study the effect of nematode (Meloidogyne javanica) on severity of tomato Fusarium wilt (Fusarium oxysporum f.sp. lycopersici race 1) and changes in Phenylalanine ammonia lyase (PAL) activity in split-root assays to show the possibility of systemic induced susceptibility caused by nematode to the fungus by local nematode infection. The results showed that the activity of nematode in one part of root confered susceptibility to Fusarium wilt in other part of the plant root and subsequently disease symptoms increased significantly in comparison to the control (without nematode inoculation). PAL specific activity showed a significant decrease in one half of split-root inoculated with fungus when the other half was inoculated with nematode as compared with the control (without nematode inoculation). Based on the results obtained in this study, nematode infection in one part of tomato plant root resulted in suppression of tomato defenses in all parts of the root, reduced tolerance or resistance to the fungus (as secondary pathogen) and intensified the fungal disease.

Zare A.H. Chizari GH.R Pykani Malmquist index computed by data envelopment analysis approach was used to estimate the total factor productivity (TFP) growth in cotton production in Iran during 1983-2001. By dividing this index in the two components, technological change and technical efficiency change, two major factors of productivity growth in cotton production were analyzed. Data was obtained from production cost system and other statistical sources provided by ministry of Jahad-e-Agriculture. Results indicated that TFP growth in cotton crop was positive (0.8% per annum) for the period of this study .This figure was different in different provinces of Iran. Maximum growth rate was 6.2% in Fars province and was negative in Kerman, Mazanderan and Golestan provinces. In comparison, technical efficiency growth was more than technological change during 1983-2001.

Hosseini M. Ghorbani M. Khaledi E. Hassanpour This paper analyzed the effect of transaction costs on supply response of rice producers in Iran. Some of these producers participate in market as sellers or buyers and others remain self-sufficient. Farmers have different responses based on fixed and proportional transaction costs. The data used in this research consisted of information about 260 rice producers in Mazandaran province in 2004. The results indicated that lowering transactions costs would increase output by both increasing market participation and increasing production for market participants. Given that transaction costs affect market participation, aggregate supply will respond to changes in the transaction cost structure through its effect on market participation. It is recommended that policies reducing transaction costs be applied as a complementary policy to price policies to affect supply response.

Falaki H. Shabanali Fami H. Iravani H. Movahed Mohammadi The continuous rapid development of telecommunications and computer-based information technology (IT) is probably one of the biggest factors of change in agricultural extension, which will facilitate and reinforce other changes. There are many possibilities for the potential applications of the technology in agricultural extension, about which attitudes of extension professionals is highly important. The present study was conducted to assess the attitude of extension professionals which can affect the adoption of IT by extension system. The population of the study consisted of 1145 extension professionals working throughout the country in different provinces. Using a stratified random sampling technique, 241 extension experts were selected as the sample for the study. The reliability and validity of the tools of study were confirmed by a pilot study and expert judgment. The results of the study indicated that the respondents had higher knowledge on word processing softwares, windows and file management in the area of computer application. In contrast, in the area of internet application they were mainly interested in getting information from specialized sites, searching by search engines of Yahoo and Google and exchanging e-mails. Correlation analysis showed that there was a significant relationship between the attitude of extension professionals and their age, educational attainments, knowledge of IT, its application and English language proficiency. Meanwhile, there was a significant difference between attitudes of male and female extension experts towards IT.

Keshavarz E. Karami Drought is an unavoidable natural disaster in dry and arid regions of the world. Studies indicate that Iran with its geographical and climatic characteristics is poor in water resources. Moreover, it is estimated that in 2025, Iran should increase the water resources by 112% in order to maintain status quo. Therefore, the occurrence of drought is more prevalent in the future. This implies a real challenge for researchers to study how to manage farms during the onset of drought. Inappropriate management strategies result in loss of resources, which in turn leads to more destructive impacts of drought, consequently leading to more droughts in future. The purpose of this survey study was to identify factors influencing drought management among farmers in Fars province, Iran. A multistage stratified random sampling technique was used to select a representative sample of farmers who has experienced drought in recent years. A total of 258 farmers were interviewed using a questionnaire. A panel of experts verified face validity. A pilot study was used to assess the reliability of the measuring instrument. Cluster analysis and Structural Equation Modeling were used for data analysis. Results indicated that farmers with different social, economical, and technical characteristics chose different management strategies when coping with drought conditions. Despite farmers' efforts to manage drought, they face harsh consequences. These consequences include economic losses and degradation of farming environment. It is therefore recommended that policy makers who are involved in drought management programs learn more about farmers' drought mitigation techniques and make further attempts to increase the efficiency and effectiveness of techniques used by farmers.

A model was constructed and applied assuming five different risks in available water and three levels of irrigation efficiencies (35, 45, and 65). The findings showed that, it is possible to direct optimal cropping pattern at basin level to maximize social profit, water use efficiency and net virtual water import simultaneously. However, in order to derive a definite conclusion, more data are needed about the quantity water embedded in each crop exported from and imported to each country. Moreover, it is necessary to design a suitable export-import plan to be used as a target for directing cropping patterns toward it. The approach used in this study can be viewed as a first step in this direction.

Zibaei M. Jafari Sani While technical efficiencies of firms that are estimated with respect to a given frontier are comparable, this is not normally valid the case among firms that operate under different technologies. Such problem arises when comparisons of firms from different regions of country are involved. This study uses the concept of the metafrontier function to investigate regional differences in milk production technologies of Iran. Metafrontier function was estimated using non-parametric data envelopment analysis (DEA) and required data are collected from 726 questionnaires. Results of estimating regional frontier production function indicated that, gap between the best producer and other producers in Yazd is minimum and it is maximum in Esfahan. Also estimation of metafrontier production function and technical gap ratio showed that Tehran and Yazd have higher technical operation in comparison with other studied provinces.

Shahedi Baking is obviously one of the most important stages of bread production. Baking time and oven temperature have greatest effects on bread quality. The aim of this study was to investigate the effect of baking time and temperature on bread quality and its shelf life. In this study, the effect of three rates of oven temperature (top and under bread surface) and baking time levels on bread quality and its shelf life was investigated. Baking temperature and time were 300 and 280 °C for 3 minutes and 20 seconds, 300 and 350 °C for 2 minutes and 30 seconds and 350 and 380 °C for 2 minutes respectively. Soluble starch and staling factors of the samples were measured. The data was statistically analyzed by complete randomized design and comparison was made between the means via Duncan,s multiple range test at 5% level. The results showed that the bread baked in various time–temperature conditions were different in moisture content. The bread baked at lower temperature and longer time had the lowest moisture. Also, the result showed that the amount of soluble starch increased by increasing the baking time and decreasing the baking temperature. The bread baked in various baking conditions showed significant differences in staling rates. Lower baking time and higher baking temperature caused the lowest bread staling rates.

Majzoobi A. Farahnaki ‏ In this research the effects of two common cooking processes of foods, namely, autoclave and extrusion cooking on the molecular and physicochemical properties of wheat starch were investigated. The results showed that the solubility of the autoclaved samples increased with increasing the temperature while their relative viscosity decreased. These findings indicated that the molecular degradation of starch could occur during autoclave cooking. Moreover, constant sedimentation coefficient (s-value) of amylose and decreasing the s-value of amylopectin with increasing the temperature further confirmed degradation of amylopectin in particular. The results of the extruded samples showed that reduction in water content may increase the shear and pressure produced during extrusion cooking, which in turn could cause several changes in starch properties including degradation of starch granules, formation of amylose-lipid complex and degradation of amylopectin (as determined by reduction of the s-values). Also, reduction in water content could increase the puffiness of the final products and reduce the cold-water and final viscosities of the extruded samples. These observations may indicate the importance of the molecular studies of starch for better interpretation of physical changes of the final products.

Abdi Gezeljeh Based on the official statistics of industries and mines organization about 1000 tons of waste of spaghetti in spaghetti- producing plants, and around 7500 tons of waste in chickpea pre-cleaning plants are produced annually in the East Azarbayjan province. In order to determine chemical composition and metabolizable energy of the above mentioned waste, at first classified random sampling from 10% of plants was performed. Then amount of dry matter, crude protein, crude fiber, ether extract, NDF, ADF, and gross energy were measured according to AOAC (1990) procedures. The amounts of crude protein, crude fiber, ether extract, NDF and ADF, for spagettti waste were, 12/7, 0/2 , 2/4 , 1/7 and 0/1 percent, respectively, and for chickpea pre-cleaning were 30/2 , 17/8 , 8/7 , 32/3 and 22/4 percent, respectively. The waste of spaghetti was mixed with basal diet with the ratios of 0, 15, 30, 45, 60, 75, 90, and 100%. The waste of pre-cleaning chickpea was mixed with basal diet with the ratios of 15% and 45%. Then, in order to determine different kinds of metabolizable energy (AME, AMEn, TME, TMEn) of waste, 30 grams of mixed feed were force-fed to 4 adult Leghorn-type roosters, according to the method described by Sibbald. The amount of AMEn of spaghetti waste in different levels was 2915, 3535, 3937, 3643, 3728, 3671, 3687 and 3717 Kcal/kg, respectively and the amount of AMEn of metabolizable energy of checkpea pre-cleaning in two levels was 2677 and 2279 Kcal/kg, respectively. Statistical analysis showed that there were significant differences between AMEn of wastes. There were significant differences between amount and kinds of metabolizable energy in different levels. The highest amount of AME was observed to be in 30% ratio of spaghetti waste relation to basal diet. There were significant differences between amount of metabolizable energy of checkpea pre-cleaning in two levels. The highest amount of AME was observed to be in 15% ratio of checkpea pre-cleaning waste related to basal diet.

Barzegar A. Karbassi J. Jamalian M. Aminlari Chitosan, a deacetylated derivative of chitin, is found in crustacean, arthropod, shell fish and shrimp shell as well as cell walls of some fungi . The objective of this research was to investigate the antimicrobial property of chitosan and possibility of its use as a natural preservative in mayonnaise. In this study, chitosan was produced by chemical method from shrimp shell. The antimicrobial activities of chitosan against Salmonella enteritidis and Lactobacillus plantarum were explored by calculation of the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) in media supplemented with 0.1, 0.2 , 0.3, ..., 0.9 , 1 mg/ml chitosan adjusted to pH 5 or 6 . The MIC and MBC of chitosan differed with pH and bacterial type, ranging from 0.4 to 1 mg/ml. Antibacterial activity of chitosan was inversely affected by pH, with higher activity at lower pH value. The sauce containing 0.1, 0.2 or 0.3% chitosan was inoculated with 106 CFU/gr S. enteritidis or L. plantarum and stored at 5°C and 25°C for 8 days. The inhibitory effect of chitosan concentration was increased from 0.1 to 0.3%. This investigation demonstrated that 0.2% chitosan can be used in mayonnaise as a new preservative.

Shahidi S.A. Mortazavi M. N. Mahalati S.H.R. Beheshti The aim of this study was to use Alpha-amylase termamyl 2-x for maltodextrin production from corn starch and evaluate its industrial uses. Based on the results obtained in laboratory, this process was accomplished in pilot plant scale. The process included preparation of starch suspension, pH adjustment, addition of enzyme, heating under stirring, continuous control of DE and Brix, enzyme inactivation in adequate DE, separation of soluble sections by centrifuge and finally spray-drying of the maltodextrin liquid. In this investigation, the amount of DE at dry matter was calculated under three enzyme concentrations (0.2, 0.25 and 0.3 ml of Alpha-amylase termamyl 2-x per Kg of starch) and in three different hydrolysis temperatures (60, 65 and 70 ºC) at constant pH (6). A completely randomized design with factorial arrangement and 5 replications was conducted. To study the relationship between DE and different parameters, multiple linear regression was used. Finally, for approximation of DE (based on enzyme concentrations, temperatures and hydrolysis times) a regression model was used. The results from different enzyme dosages at the same temperature and time of hydrolysis differed significantly (p≤ 0.05). Meanwhile, the best enzyme concentration and hydrolysis temperature for maltodextrin (high DE) production after 300 minutes were 0.25 ml of enzyme per kg of starch and 70 ºC, respectively. In these conditions, the least residual starch concentration and residual Alpha-amylase activity were observed.

Rahmani A.A. Gheisari R. Taheri A. Khodami M. Toghiani This experiment was conducted to evaluate the effects of 7 experimental diets (2 diets containing 100 and 200 mg vitamin E (VE)/kg and 5 diets containing 0, 0.5, 1, 1.5 and 2% green tea powder (GTP) ) on performance and breast and thigh meat oxidative stability of broiler chicks during different storage times. A total of 364 male broiler chicks were divided to 28 groups of 13 chicks each. Then every 4 groups were randomly allocated to one of experimental diets. During the experimental period (7-42 days of age) feed intake, weight gain and feed conversion of the experimental groups were measured. On day 42, 2 birds from each replicate (8 chicks per treatment) were weighed, slaughtered and their muscles of breast and thigh were minced and stored at 4ºC. Meat oxidative stability of the samples was determined on days 0, 6 and 9 of storage time using thiobarbituric acid test (TBA test). The results showed that addition of the VE and GTP to diets tended to significantly (P<0.05) reduce live body weight, weight gain, feed intake and abdominal fat accumulation and increase feed conversion ratio and pancreas size compared to control group. Increasing storage time from 0 to 6 and 9 d significantly (P< 0.05) increased TBA number. Lipid peroxidation and TBA values in thigh muscle were significantly (P<0.05) higher than breast muscle (1.46 vs. 0.359 mg Malonaldehyde/kg meat). Different dietary levels of GTP in diets did not have any significant effect on prevention of meat lipid peroxidation. In addition, the values of TBA in meat of the groups fed diets containing high levels of GTP significantly (P<0.05) increased in comparison to control group and those fed VE supplemented diets.

Analysis of variance indicated a significant effect of age group on staple length, fiber diameter, coefficient of variability of fiber diameter, interrupted and continuous medulla and non-medullated fibers in inner coat and yield percentage (P ≤ 0/05). The young camels had more inner coat and non-medullated fibers than other ages. The diameter least square means of 1-2 age group ( 18.54±1.47 ) was significantly different (P11 age groups (22.59±0.67, 23.19±0.57 and 24.5±0.61 , respectively). There was a significant difference (P<0.05) in shoulder, flank and total staple lengths between 1-2 and other camel age groups (P<0.0001). The results indicated that fractionation of camel hair according to age grouping (young camel separated from adult) can improve supply to market and manufacture processing.

Naeemipour Younesi H. Farhangfar M.R. Asghari A total of 1256 records associated with body weight and Cashmere at different ages (birth and 3 and 9 months) obtained from 754 Cashmere goats were used to estimate the genetic parameters in southern Khorasan province during 2000- 2003. A set of univariate animal models including additive and maternal genetic effects and maternal permanent environmental effects as well as the fixed effects of year and month of birth, sex, birth type and dam age (linear and quadratic covariates) and kid age (linear and quadratic covariates) was fitted. Co/variance components were estimated by restricted maximum likelihood procedure using Powel algorithm in DFREML software. For the body weight at 0, 3 and 9 months, models two, one and three were recognized as the appropriate models. For these models, direct heritability estimates were found to be 0.09, 0.11 and 0.09, respectively. For birth weight and weight at month 9, the magnitude of c2 and h2m were 0.18 and 0.00, respectively. For average daily gains during 0-3 and 3-9 months of age, direct heritability based on the model one was 0.16 and 0.05, respectively. Direct heritability of Cashmere was found to be 0.02. Applying repeatability model, the estimates of heritability and repeatability of Cashmere were 0.16 and 0.53, respectively. Genetic trends for birth weight (0.0175kg/year) and weight at month 9 (0.02065kg/year) were positive and non-significant. A negative non-significant statistical genetic trend (-0.00537kg/year) was found for Cashmere during the period of time.

Amanlou D. Zahmatkesh A. Nikkhah 24 Holstein cows and 16 Holstein heifers in close-up period were used to evaluate the effects of ground wheat grain in prepartum diets on health and performance of dairy cows. Cows were blocked based on parity (three groups) and then randomly assigned to two experimental diets. Study rations included a treatment containing wheat with 1.62Mcal/kg NEL, 14.8%CP, 42.1%NFC, and –64meq/Kg DCAD and another treatment was composed of barley and wheat bran with 1.59Mcal/kg NEL, 14.8%CP, 38.2%NFC, and –48meq/Kg DCAD. Cows were fed experimental diets in group, on average 24%4 days prior to parturition, and they were fed the same ration up to day 21 postpartum. Average feed intake prior to confining, milk yield and composition, blood metabolites, feeding and chewing activity, urine and feces pH, placenta weight and time of its omitted, pregnancy duration, parturition status, body weight and BCS, and metabolic disorders were evaluated in this research. Average feed intake for wheat treatment was more than barley and wheat bran treatment (11.56 in contrast to 10.74, Kg DM), but it was not statistically significant. Milk production in wheat treatment had no significant increase. Milk fat yield in wheat treatment had a higher value compared to barley and wheat bran treatment (P<0.025). Blood calcium in wheat treatment was significantly higher (P<0.005), and blood glucose in wheat treatment was significantly higher than barley and wheat bran treatment (P<0.011). Changes in body weight and BCS, pregnancy duration and parturition status were not significantly different between treatments. Urine pH in wheat treatment had a significant decrease in the last week prior to parturition (P< 0.003).

Dastar A. Khaksefidi Y. Mostafaloo This experiment was conducted to compare the effect of probiotic thepax® in diets with different quantities of protein on the performance of Cobb-500 broiler chickens and their serum antibody level against Newcastle disease vaccine (NDV). Two basal diets were formulated based on NRC (1994) recommendations which had NRC (sufficient protein diet) and 90% NRC (low protein diet) for protein. The basal diets were then supplemented with 0 and 0.1% probiotic, resulting in a 2×2 factorial arrangement with 2 levels of probiotic (0 and 0.1%) and 2 levels of protein (NRC and 90% NRC). Each of the 4 dietary treatments was fed to six replicate groups of 20 chicks. The results of experiment showed broilers fed low protein diet without supplementation of probiotic had lower performance than other treatments. Supplementing low protein diet with 0.1% probiotic significantly improved body weight gain and feed conversion ratio, as did those which were fed diets with sufficient quantities of protein. Reducing dietary protein level increased abdominal fat content, but had no significant effect on other carcass composition. Supplementing of probiotic significantly reduced abdominal fat percentage (P<0.05). The utilization of probiotic in low protein diet resulted in increasing serum antibody level against NDV, but sufficient protein diet produced no such effect. Also, the results of experiment indicated that probiotic added to low protein diet improved broilers performance and immune response. However, these effects were not observed in adding probiotic to diet with sufficient quantity of protein.

Barekatain J. Pourreza A.H. Samie S.A. Tabeidian E. Rowghani This experiment was conducted to determinate the effects of different levels of Amet protein binder (0, 1.5, 3, 4.5 and 6) in substitution for fish meal on performance and digestibility of nutrients. This study used 400 broiler chickens (Ross strain) with 5 treatments of 4 replications in a completely randomized design. Weight gain, feed consumption, and feed conversion ratio were determined at the end of each phase of the experiment. In addition, the digestibility of nutrients and apparent metabolizable energy (AMEn) of the whole diets were measured by sampling excreta. The results showed that levels of 4.5 and 6% of Amet significantly decreased feed consumption (P< 0.01). Feed consumption was higher for 1.5, 0(control), and 3% Amet in diets, respectively. At the starting phase, 1.5% Amet treatment improved feed conversion ratio (P<0.01). The treatments 6% and 4.5% Amet increased feed conversion ratio in all phases of experiment and the final phase. Percentages of abdominal fat were not significantly affected by treatments. Replacement of different levels of Amet except the treatment 6% had no significant effect on percentage of carcass. The level of 1.5% Amet versus control significantly increased AMEn (P<0.01). It seems that the inclusion of 1.5% Amet binder in the diet can positively affect performance and AMEn of diet in broiler chickens.

Fazaeli This study was conducted to assess the effect of culturing oyster mushroom (Pleurotus florida) on the nutritive value of wheat straw. In a completely randomized design, chemical composition and in vitro digestibility of untreated and fungal treated wheat straw were measured by the following treatments: 1) untreated wheat straw (UWS) 2) fermented wheat straw before mushroom fruiting (FTWS) and 3) fermented wheat straw after mushroom harvesting (SPWS), with 4 replicates. In addition, the in vivo digestibility and voluntary intake were determined using 4 cows and 4 sheep and nutritive value index was estimated. The crude protein and in vitro digestibility increased whereas organic matter and cell wall components decreased significantly (P<0.05) in FTWS and SPWS. In vivo digestibility and voluntary intake increased in FTWS when fed to sheep or cow (P<0.05) but no significant differences were found between SPWS and UWS. The digestible dry mater and organic mater intake (g/kg W0.75) were significantly higher (P<0.05) in cow than sheep. The significantly (P<0.05) highest amount of nutritive value index was obtained for FTWS fed to cow and the lowest amount was found for SPWS when fed to sheep. It can be concluded that culturing Pleurotus florida on wheat straw can improve its nutritive value before mushroom fruiting .

Farhangfar H. Naeemipour R. Lotfi This study was undertaken to estimate genetic trend and parameters of Holstein cattle in Khorasan province for milk yield using a spline random regression test day animal model. A total of 32854 monthly test day milk records (twice and thrice a day milking) obtained from 3842 Holstein heifers (progeny of 466 sires) distributed in 125 herds and calved from 2001 to 2005 was used to predict breeding value of individual animals. In the model, fixed effects of herd including year-month of recording, milking times, age at calving (linear and quadratic covariables), Holstein gene percentage (linear covariable) as well as random effects of additive genetic and permanent environment were studied. To take account of the shape of the lactation curve at genetic and environmental levels, cubic spline polynomials were also included in the test day model. Bayesian method by applying Gibbs sampling technique (100000 chains applying RRGIBBS software) was utilized to obtain posterior means of predicted breeding value of animals for milk yield at individual month of lactation. The results showed that mean of breeding value for 305-day milk yield was 52.90 kg (p<0.05). Spearman rank correlations between predicted breeding values at different months of lactation decreased as the interval between them increased. The highest and lowest rank correlations were found between months 8 and 9 (0.998) and between months 1 and 10 (0.312), respectively. Predicted breeding value of 305-day milk had the lowest and highest rank correlations with predicted breeding value at months 1 (0.553) and 6 (0.990), respectively. Regression analysis of average predicted breeding value of progenies in their birth year showed that the amount of genetic trend for 305 day milk yield was 17.75 kg per year, statistically no different from zero (p value=0.165).

Ashayerizadeh B. Dastar M. Shams Shargh M. Khomeiri ‏ This experiment was conducted to determine the performance and intestinal microflora population of broiler chicks in diets supplemented with Roxarsone, Avilamycin and Formycin gold during starter period. A basal diet was formulated according to NRC (1994) recommendation for starter (0-21 d) period and also supplemented with appropriate amounts of the mentioned growth promoters. Each of the treatment was fed to 5 replicates of 18 Ross 308 male broilers. The birds were raised on pen floor for 21 days. The microflora population in crop and ileum parts was measured on appropriate bacteriological media. Results of experiment indicated that supplementation of Roxarsone and Avilamycin, especially their combination to broiler diets, significantly improved body weigh gain of birds (P<0.05). Feed consumption and feed conversion ratios were not affected by any of the mentioned growth promoters. Adding all the growth promoters to the basal diet, except for the treatment of 0.05 percent Formycin gold, decreased total bacterial numbers in crop and ileum parts. Broilers fed diets containing Roxarsone plus Avilamycin had the lowest total bacterial population and were significantly different from those fed the basal diet (P<0.05). Supplementing broiler diets with all the growth promoters increased lactic acid bacteria population in crop, and decreased coliforms population in ileum parts. Lactic acid bacteria population was the highest in broilers fed Roxarsone plus Avilamycin and coliforms population was the lowest in birds fed 0.2 percent Formycin gold, being significantly different from basal diet (P<0.05).

Rahimmalek B.E. Sayed Tabatabaei S.A. Mohammadi Genetic maps with high genome coverage are becoming increasingly useful in both basic and applied genetic researches. In the last decades, the advent of DNA markers has brought about a magnificent revolution in the production of genetic map, especially in wheat. In the present study, AFLP markers were used to saturate linkage map of 107 doubled haploid individuals produced through Fukuho _Komugi × Oligo – Culm crosses received from Japan International Research Center of Agricultural Science (JIRCAS). The framework of genetic map was used as base map for next analysis. AFLP analysis was performed with MseI / PstI as digestive enzymes. The average percentage of polymorphism with AFLP markers was around 16.6%. Data analysis was performed by computer program known as Mapmaker / EXP, Ver. 3.3. In this program, the maximum distance criterion was 50 cM and the minimum LOD equated 3. The drawing of chromosome schema for the linkage groups was performed by Draw map, Ver 1.1. In this analysis, 115 AFLP markers were divided into 10 groups in addition, some of the markers remained unlinked. The supplementary data analysis along with specific SSR markers identified the chromosome loci of the markers. Ultimately, 71.1% of the markers were assigned to genome A, 16.5% to genome B and only 3% to genome D. The AFLP markers filled 11 gaps in 7 chromosomes (2A, 3A, 7A, 2B, 3B, 5B and 7B). The low coverage of genome D was due to the limited polymorphism and its conservation in different populations. Among the chromosomes, maximum number of markers (60) was assigned to the chromosome 7A. The distribution of the markers on this chromosome was not uniform. Such a distribution was related to the grouping AFLP markers within heterochromatin region, particularly around the centromere.
