Kaviani Salinity is one of the most important ecological stresses which have undesirable effects on seed germination. This study was carried out to evaluate the germination of three species of lawn (Poa pratensis, Lolium perenne, Cynodon dactylon) seeds under salinity stress. The effect of different treatments (Gibberellins 50 mgl-1, 2% CaCl2 and hydroprimig in 24 hours) was evaluated on total germination, mean daily germination, maximum and mean germination percent in three species of lawn, under four levels of salinity (0, 3, 6, 9 dS/m). Priming factor (Gibberellins and water) was more effective than salinity on the seed germination. Among lawn types, Lolium perenne and Cynodon dactylon indicated greater seed germination percentage and germination rate. The least rate and percentage of germination belonged to Poa pratensis. Among priming treatments, gibberellins had the greatest effect on germination, followed by hydropriming. However, interaction effects of "Lolium × CaCl2" were greater than other treatments on the mean daily germination and germination value. Based on the results, seed priming specially Gibberellins could be an appropriate substrate to improve seed germination in lawns, when grown under salinity.

Jalali To investigate the effect of three methods of bed preparation on yield, yield components, and amount of water used in three rice cultivars, a study was carried out in two regions, including Fozve Research Station (Isfahan Agricultural Research Center) and Zarinshahr, using a split plot experiment based on a complete block design in three replications in 2007. Three bed preparation methods (conventional, using roller and rotivator) were assigned as main factors and three rice genotypes (Sazandegi, Zayandehrud, and Line2) as sub-factors. The number of fertile tillers, plant height, panicle length, grain yield, yield components and percentage of hollow grains were measured. In Zarinshahr area, using rotivator led to higher grain yield in all the cultivars, compared to using roller and traditional methods. In this study, the highest grain yield (8700 Kg ha-1) was obtained using rotivator and the line2 cultivar in Zarinshahr area. The stem lodging extent in Zarinshahr, with the use of rollers in all cultivars, ranged from 15 to 25 percent, while the range for different cultivars, in conventional methods of bed preparation and use of rotivator was variable from 35 to 45 percent. The results of this study showed that although using both methods of rotivator and roller had higher yield than conventional methods of bed preparation, the use of roller, with lower water consumption per hectare in two regions of the Zarinshahr and Fozve, was proven more effective in reducing consumption of water per hectare. Based on the amount of water consumed, the use of roller and rotivator for bed preparation seems superior to the conventional method.

Arvin Seed pretreated with plant growth regulators can improve germination parameters, growth, and yield of crops. Thus, in two greenhouse and field experiments, effects of seed treatment with 0.1 mM salicylic acid (SA), 1µM methyl jasmonate (MJ), 1.5% humic acid (HA), and water (as Control) on germination parameters, seedling growth, and also growth and fruit yield were studied. In the first experiment which was conducted on two cultivars (Semsuri and Shahpasandi), all the treatments improved most of parameters the recorded, and the response of two cultivars was rather similar for most parameters. In the second experiment which was conducted on one cultivar (Shahpasandi) in the field, all the treatments improved most of parameters the recorded. Compared with the control, SA, MJ and HA increased total plant fresh weight (19, 41 and 19%), fruit number (30, 35 and 20%) and fruit yield (31, 45 and 31), respectively. Significant correlations were found between fruit yield and relative water content (r = -0.95*), ion leakage (r = -0.93*), final plant shoot fresh weight (r = 0.99**) and fruit number (r = 0.93*), indicating that treatments could increase fruit yield by improving ion leakage and relative water content.

Ramin A greenhouse study was undertaken to assess the salt tolerance of two citrus rootstocks, namely, Bakraii (Citrus sp.) and Trifoliate orange (Poncirus trifoliata). A factorial experiment through a completely randomized design (CRD) with three replications and four levels of salt including 0, 20, 40 and 60 mM NaCl was conducted. After eight weeks of treatment, number of leaves, plant height, leaf area, wet and dry weight of leaf, stem and root, length of root, chlorophyll content, net CO2 assimilation rate (ACO2), stomatal conductance (gs), transpiration (E) and water use efficiency (WUE) and ion concentrations were measured. Salinity decreased growth and net gas exchange. Trifoliate orange showed the most decrease in growth indices and net gas exchange compared with Bakraii. The ability to limit the transfer of sodium to leaves in low levels of salt was observed in Trifoliate orange, but this ability was not observed in high levels of salt. Results showed that accumulation of chloride in leaves and roots were less in Bakraii compared to the Trifoliate orange. The lower Cl- concentration in leaves of Bakraii than trifoliate orange suggests that the salinity tolerance of Bakraii is associated with less transport of Cl- to the leaves. Salinity increased K+ and decreased Mg2+ and Ca2+ concentrations in leaves of both rootstocks. It is proposed that salt stress effect on plant physiological processes such as changes in plant growth, Cl- and Na+ toxicity, and mineral distribution, decreases chlorophyll content and reduces the photosynthetic efficiency of these citrus species.

Majidi The major problems in transplanting the landscape trees are high level of mortality and low establishment rate of transplanted trees, especially in the first year. In order to achieve the best condition for successful transplanting of pine and plane trees in Isfahan landscape, the present study was carried out based on a completely randomized block design with four replicates and three treatments including transplanting method (balled and burlapped and bare root), tree age (immature and mature) and IBA application (0 and 150 mg/L). Trees were transplanted during 2009 and 2010 in three times (dormant season, early and late growing season). Survival rate and Relative Growth Rate index based on tree height (RGRH) and trunk diameter (RGRD) were measured during the first and second years. Trees transplanted early in the growing season showed the most survival percentage during the two years, as compared to other transplanting dates. Survival of Balled and burlapped and immature transplanted trees was significantly greater than bare root or mature trees. The significant effect of age treatment was continued in the second year. IBA treatment had no effect on survival rate of the studied species. Balled and burlapped and immature transplanted pine trees also had higher RGRH and RGRD compared to bare root or mature trees. According to the results of this study, early growing season is the best time for transplanting pine and plane trees. Also, transplanting of immature trees using balled and burlapped method is recommended to increase the survival and establishment rate.

Gilani This study aimed at evaluating the effect of different planting dates (different ambient temperature conditions) on the characteristics of rice panicle and yield of its cultivars in Khuzestan climate in 2010. The experimental design was a split plot in a Randomized Block Design with four replications. The main factor was the planting date with three dates (May 25th , June 9th , and June 25th ) and the sub factor consisted of three rice cultivars including Red Anbori (long and short), and Champa. Results showed that the highest grain yield, seed weight in each panicle, grain number, and 1000-grain weight belonged to the third planting date the highest fertility percentage belonged to the second planting date and the highest number of unfilled seeds in panicle and weight of unfilled 1000-grain were observed in the first planting date. With an average of 3795.4 Kg/ ha, Champa cultivar had the highest grain yield. In addition, given the correlation coefficients, grain yield had the most positive and significant correlations with 1000-grain weight (0.779*), weight of each panicle`s seeds (0.755*), and the number of filled seeds per panicle (0.403*), which indicates the high and direct impact of these characteristics on the increase of yield as well as the necessity of conducting further studies to increase the yield.

Souri Calcium and boron as plant nutritional elements play major roles in plant physiological processes including regulating various cell and plant functions. Considering the importance of both elements, this study was conducted during 2010-2011 in the Experimental Asian Pear Orchard at Faculty of Agriculture, Tarbiat Modares University. Different concentrations of calcium chloride (0, 0.5 and 0.7 percent) and acid boric (0 and 0.5 percent) were used as foliar spray of Asian pear cultivar "KS10" during growing season. The results showed that foliar application of calcium and boron led to the improvement in physicochemical characteristics of pear fruits. Under treatment conditions, fruit tissue hardness increased, while total soluble solids decreased. Various concentrations of calcium resulted in decreasing fruit softening, although after 3-months' storage all treatments showed low fruit firmness. Total phenolic compounds decreased more significantly in control fruits compared to in fruits sprayed with calcium and/or boron during the storage. The highest and lowest levels of polyphenol oxidase activity were found in elements-sprayed fruits and non-sprayed ones respectively. In brief, calcium and boron application resulted in improving postharvest characteristics of Asian pear fruits and reducing internal browning symptoms.

Kazemi Determination of growth rate and planting space of trees in urban spaces is needed for the planting design programs and land scape management. To determine the growth rate of two tree species, Chinaberry (Melia azedarach) and Mulberry (Morus alba), data was collected on different dimensions of these trees including, tree height, tree crown height and tree crown diameter at various ages at Pardis campus of Ferdowsi University of Mashhad during their growth. Regression analysis of these dimensions as a dependent variable and age as an independent variable produced different models that can be used for estimating the growth of the measured dimensions of these two species. The results showed that the highest regression coefficient among the models was linear, polynomial and exponential function, but logarithmic types were selected as the most acceptable model for estimating the growth of measured dimensions in the two tree species of Chinaberry (tree height with r2=0.87, crown height with r2=0.67, crown diameter with r2=0.67) and Mulberry (total height with r2=0.60, crown height with r2=0.40, crown diameter with r2=0.65). Also, in both species, the most increase in growth rate of measured dimensions for the 15 years old trees was found in crown diameter.

Siadat This experiment was conducted in 2005-2006 at Safiabad Agricultural Research Center to assess the effects of sowing date on the yield of canola genotypes. The design was a split plot in a completely randomized block with 3 replications. Main plots consisted of 3 levels of sowing date (November 1st , November 16th and December 1st) and subplots included 7 canola cultivars (Hyola60, Hyola308, Hyola330, Hyola401, Hyola420, RGS003 and Option500). Grain yield was decreased by 5.72% and 21.27% in the second and third sowing dates compared with the first one, respectively. The results of interaction between sowing date and cultivars showed that the highest grain yield (5055.09 Kg/ha) at the first sowing date (Nov 1st) belonged to Hyola420 cultivar and the lowest grain yield (2360.68 Kg/ha) at the third sowing date (Dec 1st) to the Option500 cultivar. The number of pods per plant was decreased by 20.61% and 36.02% in the second and the third sowing dates compared with the first one, respectively. The highest (28.93) number of grains per pod belonged to Hyola401 cultivar sown on December 1st and the lowest (15.69) ) number of grains per pod belonged to Hyola60 cultivar sown on December 1st. Considering the results of the experiment, the sowing date of Nov 1st for Hyola420 cultivar, and Nov 1st and Nov 16th for other cultivars could be appropriate.

Fathi In order to investigate the effect of silicon application on some physiological characteristics, yield and yield components, and grain mineral contents of bread wheat (Triticum aestivum) under water stress condition, an experiment was conducted in Ramin Agriculture and Natural Resources University, Khuzestan, in 2012. The experiment was arranged in split-plots design in RCBD (Completely Randomized Blocks Design) with three replications. Treatments consisted of drought stress (irrigation after 25, 50 and 75% depletion of Available Water Content) in main plots and silicon (0, 10, 20 and 30 Kg Si ha-1) arranged in sub-plots. Results showed that the effect of drought stress was significant on most traits and led to the increase of electrolyte leakage (EL), cuticular wax, leaf and grain silicon content and grain nitrogen content. But drought led to negative impacts on grain yield and its components, and leaf potassium content, i.e. moderate and severe stresses reduced yield by 17% and 38% compared to control, respectively. Effect of silicon application was significant on all traits except for spike per square meter. Silicon had the greatest impact on EL and led to 35% decrease in this trait. Also, silicon led to increase in leaf and grain silicon contents and grain K content and grain yield and yield components, when applied at 30 kg ha-1. Generally, application of 30 kg ha-1 of silicon led to 6 and 14% increases of grain yield at the presence of moderate and severe drought stresses, respectively. Thus, given the abundance of silicon it can be used as an ameliorating element for planting bread wheat in drought-prone conditions.

Eshghizadeh This study was carried out in two separate experiments in order to evaluate the responses of different safflower (Carthamus tinctorius L.) genotypes to salinity at germination and vegetative growth stages. In both experiments, thirteen safflower genotypes were investigated under non-saline and saline conditions (100 mM sodium chloride). Germination experiment was done in the seed laboratory and the experiment regarding the response of plants at vegetative stage was carried out inside a research greenhouse, Faculty of Agriculture, Isfahan University of Technology, using hydroponic culture in 2009. In this experiment, the germination rate and percentage, the root and shoot length of germinating seeds, plant height, leaf area, shoot and root dry matter were decreased under the salt treatment. The effect of salinity was not significant on shoot/root weight ratio. The interaction effects of salinity and genotype were significant on germination traits, plant height, and root dry weight. The reductions in shoot dry matter in saline compared to non saline treatment were about 32 percent for the most tolerant (A1) and about 60 percent for the least tolerant genotype (C121). Considering all traits evaluated in this study, genotypes E1431, A1, and LRV51-51 at germination stage and genotypes IL111, A1, and Arak2811 at vegetative stage were the most tolerant compared to other tested genotypes when subjected to the salinity level of 100 mM sodium chloride. Except for genotype A1, no significant relationship was found between salinity tolerance of safflower genotypes at germination and vegetative growth stages.

Allahgholipour To determine gene action and heritability of grain yield related traits in rice, six rice varieties including Hashemi, Vandana, Kadous, Hassani, Shahpasand and IR36 were crossed in a diallel design in 2010. The parents and seeds of F1 generation (36 genotypes) were grown in a completely randomized block design with three replications at the Research Field of the Rice Research Institute of Iran-Rasht in 2011. In this experiment, the yield related traits including grain yield, number of panicles per plant, number of spikelet’s per panicle, 1000-grain weight, plant height, panicle length and flag leaf area were measured in each experimental unit. Evaluation of the gene action based on the Hayman graphical method indicated that 1000-grain weight was controlled by partial dominance effect and the other attributes were controlled by complete dominance to over-dominance effects. Broad-sense heritability varied from 54.91% to 99.84% for flag leaf area and plant height, respectively and narrow-sense heritability ranged from 26.04% to 88.68% for panicle length and 1000-grain weight, respectively. Results of this research showed that the additive gene effect can be used to improve several traits including 1000-grain weight, but utilizing the heterosis phenomenon and hybrid production is recommended to improve the remaining traits in the studied population.

Shekari In order to study the effect of different intercropping combinations on some maize qualitative traits, an experiment was conducted as a completely randomized block design with three replications in Agricultural Research Station, Faculty of Agriculture, University of Tabriz, Iran, in 2006 and 2007. Two maize (Zea mays L.) hybrids (704, 301), vetch (Vicia villosa), bitter vetch (Vicia ervilia), berseem clover (Trifolium alexandrinum L.) and common bean (Phaseolus vulgaris) single crops as well as intercrops of maize hybrids with legumes were used. The results showed that neutral detergent fiber and acid detergent fiber of forage maize in intercropping with legume decreased. The lowest neutral detergent fiber (NDF) was obtained from 301 hybrid-vetch mixture and 301 hybrid –bitter vetch mixture. The NDF was used to predict DMI and was negatively correlated with DMI, which means that when NDF is low the quality and DMI are high. Also, the lowest ADF content was achieved in intercropping of 301 hybrid with bitter vetch, vetch and bean. As ADF decreased there was an increment in TDN, which means that animals are able to utilize the nutrients present in the forage. In conclusion, with the decrease of NDF and ADF in intercrops, DMI, TDN and net energy for lactation (NEL) content increased. Intercropping of maize with legume improved the forage quality in terms of TDN, DDM, NEL, NDF and ADF concentrations, as compared with the single cropping of maize.

Emam yaemam@gmail.com The current study was conducted to evaluate the effect of different salicylic acid levels on salinity tolerance of barley as a factorial experiment based on a completely randomized design in the controlled conditions in College of Agriculture, Shiraz University, in 2013. In this study, the effects of four salicylic acid concentrations (0.0, 0.5, 1.0 and 1.5 mM) were examined on growth, yield, yield components, ions content, and activity of antioxidant enzymes of barley (cv. Reyhane) under five salt stress conditions (tapwater as control, 5, 10, 15 and 20 dS m-1). The results showed that salt stress caused a significant reduction in plant height (%41.1), leaf area (%23.4), grain number per ear (%19.5), dry weight (%26.8), grain yield (%34.6), and shoot potassium concentration (%28.2). Furthermore, salinity significantly increased shoot sodium concentration (%239.4), activity of catalase (%46.0), superoxide dismutase (%256.6), and peroxidase (%760.3). Salicylic acid, depending on the concentration, had a positive effect on growth and other measured traits, with the highest effect found in 1.0 and 1.5 mM salicylic acid in most cases. The interactions also showed that salicylic acid application and increase of its concentration compensated for some negative impact of salt stress on growth, yield, ions content and activities of antioxidant enzymes. By contrast, 0.5 mM salicylic acid had no significant effect. Overall, the result of this study indicated that exogenous application of salicylic acid increases salinity tolerance of barley, with a change in sodium/potassium absorption, as well as, an increase in the activity of antioxidant enzymes.

Tabatabai The aim of this study was measuring nitrate and leaf chlorophyll content in aerial parts of plant, from which we can predict the hypocotyl nitrate content of radish. A factorial experiment in a completely randomized design with five replicates was carried out on two varieties of radish (Cherry Belle and Sparker). Plants were grown in perlite containing pots and were treated with five levels of N (0, 25, 50, 100 and 200 mg/l). Vegetative traits including leaf area, leaf and hypocotyl fresh and dry weight, hypocotyl length and diameter, and hypocotyl and petiole nitrate levels in fresh and dry matter, soluble solids in hypocotyl and petioles, and leaf chlorophyll index were measured. A positive correlation between leaf chlorophyll index and nitrate level in hypocotyl dry matter was observed at harvest time (r2 sparkler = 0.841, r2 cherry belle = 0.869). Significant positive correlations were also found between hypocotyl and petiole nitrate level in fresh matter, and between leaf and nitrate level in hypocotyl dry matter. Based on equations obtained from this study, we can claim that increase per unit in petiole nitrate content could result in the increase of 0.212 and 0.266 units in hypocotyl nitrate content, respectively, in Cherry belle and Sparkler varieties. Results showed that petiole sap test is a rapid and valid technique for describing nitrate status of radish plants.

Houshmand2 The experiment was conducted in 2012 to evaluate the effect of salinity stress on oil percent, oil yield, seed yield and some physiological charactristics on three local populations of castor bean (Ricinus communis L.), at the University of Shahrekord, Iran. Experiment was carried out with three replications in a completely randomized design including five levels of salinity (1.2, 2, 2.6, 3.8 and 4.8 dS/m in soil saturation paste) as the first factor and castor populations (Shiraz, Kerman and Urumieh) as the second factor. The effect of salinity was statistically significant (α>0.01) on seed yield, oil percent and oil yield, chlorophyl a, chlorophyll b and proline, while a significant effect (α>0.05) was observed for total chlorophyl. The results also showed that different populations had a significant difference (α>0.01) with regard to all studied factors. The highest and the lowest proline content were observed for Kerman and Shiraz populations, respectively. Increasing salinity increased the leaf proline content while it decreased the chlorophyll content was decreased. At low salinity levels, Shiraz population resulted to the highest seed and oil yield. However, with increasing salinity, seed yield and oil content of Shiraz population was less than other populations. Although more research is needed in this respect, but it seems that in castor been Shiraz population for soils with a low salinity and Kerman population for more saline conditions can be recommended.

Bahrami This research was conducted to study the amount of self- incompatibility in 25 genotypes of Bromus inermis, under two water environments (non-stress and drought stress) in a completely randomized block design. For this purpose, half of the panicles of each genotype were bagged for obligate selfing and the others were allowed to open pollination. Results showed that under non-stress condition the average number of seeds per panicle for open pollination was 161.4 and for selfing mode was 5.6, indicating the high rate of self-incompatibility in this grass. Under drought stress condition, these values were 142.8 and 4.7, respectively, showing the effect of relative environmental conditions (drought stress) on seed production in regard to both the selfing and crossing. The same trend was also observed for seed weight. Under non-stress condition, variation among genotypes for seed weight per panicle was more than the stress condition. High variability was observed among genotypes for self-compatibility index, and thus the genotypes with the highest and lowest incompatibility index were determined.

Amini Sulphur dioxide (SO2) is one of the major atmospheric contaminant that induces negatively effects in the cellular biochemistry and physiology of the plants. However, Rhizobium inoculation can cause increas in plant resistance to abiotic and biotic stresses. In this study, effects of different concentrations of Sulphur dioxide gas (0, 0.5, 1, 1.5 and 2 ppm) on photosynthetic pigments, proline, protein, sulphur, potassium and phosphorus of inoculated alfalfa with Rhizobium (native and standard strains) were evaluated in Arak city. The Results showed that high concentrations of Sulphur dioxide (1, 1.5 and 2 ppm) caused a decline in photosynthetic pigments, protein, potassium and phosphorus and an increase in sulphur and proline content of alfalfa plant in compared to the controls. In low concentration of SO2 (0.5 ppm), the increase in photosynthetic pigments, protein, potassium and phosphorus were observed. Rhizobium inoculation itself caused an increase in photosynthetic pigments, protein, potassium and phosphorus contents but did not effect on the proline content and sulfur uptake. Inoculation of alfalfa with two strains of Rhizobium decreased induced effects of high concentrations of SO2 on these biochemical parameters significantly (at 0.01 level) in comparison with the control plants. Therefore, rhizobial inoculant be able to increase host plants resistance to SO2 pollution stress and have been applied as a biofertilizer.
