The wide ecological and environmental dispersion of crop wild relatives, generates a high potential of their adaptive diversity to abiotic stresses such as drought. In this study 21 (including 10 cultivated and 11 wild barley (Hordeumvulgaressp. spontaneum))genotypes were evaluated under three soil water conditions for grain yield, drought tolerance indices (STI and YSI) and some physiological traits during two growing seasons(2012-2013 and 2013-12014). High genetic variation was observed for grain yield and STI and YSI indices between and within cultivated and wild barley groups of genotypes. Differences were also observed between the genotypes for physiological traits. Different responses of the genotypes to different levels of drought stress were also observed for all of the measured traits. The high-yielding varieties were more tolerant based on STI index, but the average of yield stability under stressed conditions (YSI) was significantly higher in the wild barley group of genotypes comparing to cultivated ones, indicating a high level of drought tolerance in wild genotypes. Among physiological traits, significant differences were observed for relative water content and proline content between cultivated and wild barley genotypes, showing the importance of these two traits in different response of the two genotypic groups to drought stress. The STI and YSI indices identified the most drought tolerant genotypes at different soil moisture levels. The tolerant genotypes were mostly belonged to wild barley. These genotypes can be used in breeding programs by crossing them with high-yielding varieties such as Reihan 03 for increasing drought tolerance of cultivated barley.

Treatments were three levels of saline irrigation water (0.4 as control, 7 and 14 dS/m) and three sorghum cultivars (Pegah, White speedfeed and Red speedfeed) as main plots and subplots, respectively. Results showed that salinity stress decreased plant height and leaf area. Pegah cultivar showed the highest forage dry weight in all salinity treatments. Activity of antioxidant enzymes including superoxide dismutase, peroxidase and catalase significantly increased with increasing salinity levels in Pegah and Red speedfeed cultivars. In salt-stressed Pegah these enzymes activity increased 2.1, 4.5, and 2.8 times, respectively in comparison to control. With increasing salinity levels, shoot sodium/potassium ratio of White speedfeed, Red speedfeed, and Pegah cultivars increased  10.7, 6.8, and 1.7 times, respectively whereas root sodium/potassium ratio of the cultivars increased 9.6, 8.1, and 4.7 times, respectively. It seems that the lower absorption of sodium was the major mechanism of salinity tolerance in Pegah and can be an important criterion to evaluate sorghum salinity tolerance Antioxidant enzymes activity Forage dry weight Sodium/potassium ratio 2017 8 01 19 31 http://jcpp.iut.ac.ir/article-1-2346-en.pdf 10.18869/acadpub.jcpp.7.2.19

Isfahan University of Technology - Journal of Crop Production and Processing 2251-8517 2251-8525 2017 7 2 Hybrid vigor estimation in some fresh Cucumber Hybrids Fatemeh Moradipour moradipour21@gmail.com Jamal-Ali Olfati jamalaliolfati@gmail.com Yousef Hamidoghli hamidoghli@gmail.com Atefeh Sabouri atefeh_sabouri@yahoo.com Bahman Zahedi bzahedi@yahoo.com Since cucumber is one of the most economically important horticultural crops, production of hybrid seeds is very important for obtaining a profitable fruit yield. Detecting the best combination of the parents is one of the most important stages in each breeding program. By selecting parents with high heterosis in their progenies, breeders will be able to generate hybrids with high yield. This study was, thus, undertaken to examine heterosis effect on yield, yield components, and some qualitative characteristics in some fresh cucumber fruit hybrids and to select the best cross. Eighteen cucumber hybrids along with a standard national hybrid “Guilan 2” generated by VBG Company and a standard international hybrid 'PS' were planted in the Research Field of Lorestan University, Khoramabad, Iran, during 2013-2014. There were significant differences between genotypes for all measured characteristics. The mean comparison for different traits showed that B10×A4 hybrid had the highest total and marketable fruit yield and B12×A0 hybrid had the greatest early fruit yield. The greatest high parent heterosis, mid-parent heterosis and standard heterosis were belonged to B10×A11 and B10×A4 hybrids, for total fruit yield and marketable fruit yield, respectively. The greatest mid-parent heterosis and high parent heterosis were also related to B12×A0 and B10×A15 hybrids, for early fruit yield and time to first female flower appearance, respectively. Since there were notable differences between studied hybrids in terms of a number of examined traits, they can be used in crossing programs with the aim of releasing suitable hybrid cultivars Heterosis Fresh type Cucumber Yield Dominant 2017 8 01 33 46 http://jcpp.iut.ac.ir/article-1-2567-en.pdf 10.18869/acadpub.jcpp.7.2.33

Isfahan University of Technology - Journal of Crop Production and Processing 2251-8517 2251-8525 2017 7 2 Evaluation of economical yield and radiation use efficiency of maize and cotton in sole and ‎intercropping systems as affected by different levels of Nitrogen Rooholla Moradi roholla18@gmail.com A Koocheki M Nasiri Mahallati In order to study the potential of maize-cotton intercropping for improving radiation use efficiency (RUE), an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications at experimental filed of Ferdowsi University of Mashhad. The experimental treatments were nitrogen in four levels (0, 50, 100 and 150 Kg N ha-1) and planting pattern in three levels (maize and cotton sole cropping and maize/cotton intercropping). LAI, dry matter and yields of maize and cotton were measured during the growing season. The results showed that economical yields of maize and cotton were significantly increased as affected by increase in N level. Economical yields of both crops in sole cropping were higher than intercropping system due to higher plant density. LAI and intercepted PAR in intercropping system were higher than sole cropping, and the traits were improved by increasing N levels. In all the N levels, LERPAR was greater than one, which represents the positive role of intercropping on radiation intercept compared to sole cropping. In general, the results showed that RUE in intercropping system was higher than sole cropping of the two species. Also, maize had higher RUE in comparison with cotton in all the experimental treatments. It seems that the intercropping system can be considered an appropriate approach for efficient use of resources.

Therefore, in order to evaluate the effect of transplanting method on cotton quantitative and qualitative traits, a 2-year field research was carried out using a split plot design experiment with different planting dates as main plot and two planting methods (planting 30 days old plantlet and seed sowing) as subplot based on randomized complete block design with four replications at Agricultural and Natural Resources Research Station of Kashmar, east of Iran during 2009 and 2011. All traits except yield were decreased significantly with a delayed planting in the first year and transplanting method led to a non-significant increase (9 percent) in yield, compared to seed sowing. A delayed planting reduced mean yield (35.6 percent) and its components significantly in the second year. Planting of 30-days old cotton plantlets increased the yield (33.9 percent) significantly. The amount of reduction in yield due to delay of planting was lower in transplanting method compared to the seed sowing method. Fiber quality attributes were decreased in a delayed planting, except fiber length. Nevertheless, planting of cotton by transplanting method improved the fiber quality attributes in late planting dates.   Cotton Fiber quality Planting date Seed cotton yield Transplant 2017 8 01 61 72 http://jcpp.iut.ac.ir/article-1-2340-en.pdf 10.18869/acadpub.jcpp.7.2.61

Apple trees were sprayed 5 times with CaCl2, CaO, Ca-EDTA and Ca(NO3)2 salts with an interval of 20 days from late June until early October. After harvesting fruits were kept in cold storage at standard condition for 150 days. Nitrogen, phosphorus, potassium, calcium, magnesium, ascorbic acid, total soluble solids, firmness, total acidity, catalase enzyme activity and total antioxidant activity at harvest time, 50, 100 and 150 days after cold storage were measured. The results showed that the effect of foliar application on catalase enzyme activity, total antioxidant, pH, soluble solids, total acidity, calcium, firmness and ascorbic acid was significant. At the end of storage period, calcium amount of fruits at the presence of Ca-EDTA, CaCl2, Ca(NO3)2 and CaO treatments increased by 77.5, 27.5, 22.3 and 10.1 percent, respectively. Catalase enzyme activity in Ca-EDTA treatment increased 91.8 percent after 150 days of storage compared to control. At the end of the storage period, the highest content of ascorbic acid was found in Ca-EDTA treatment (6.04 mg per 100 g FW). It is concluded that spraying of apple fruit with Ca-EDTA can improve and maintain most fruit qualitative properties and increase enzymatic and antioxidant activity during storage time.  Calcium chelate Catalase enzyme Storage Firmness 2017 8 01 73 87 http://jcpp.iut.ac.ir/article-1-2302-en.pdf 10.18869/acadpub.jcpp.7.2.73

Sampling time was considered as main factor. Five samplings were performed after imposing the irrigation treatments. The factorial combination of two irrigation intervals (75 (unstressed control) and 120 mm evaporation from Class-A pan) and two siderophore application treatments (with and without application) were considered as sub factors. The foliar application of siderophore (2000 mg l-1) was applied two times. In addition, 20 kg siderophore ha-1 was applied with irrigation. The chl a, b and carotenoids decreased with delay in irrigation while increased with siderophore application in each irrigation. Also, proline, soluble sugars and sucrose accumulated with increasing irrigation intervals and delay in irrigation. Increase in intervals and delay in irrigation without siderophore application resulted in an increase in membrane lipid peroxidation. The trend of changes in traits was significantly influenced by the availability of soil moisture, and modifications in the above-mentioned trait values were observed with delays in irrigation. Irrigating (rewatering) of plants subjected to water deficit stress did not improve their traits values compared with the unstressed control, indicating that short-term effects of drought would not recover by irrigation. Bacterial siderophore enhances the ability of osmotic adjustment and photosynthetic capacity and is effective in ameliorating the harmful effects of drought Delayed irrigation Maize Osmotic adjustment Siderophore 2017 8 01 89 102 http://jcpp.iut.ac.ir/article-1-2588-en.pdf 10.18869/acadpub.jcpp.7.2.89

Treatments included conventional corn herbicides application (Nicosulforun, Foramsulfuron, Eradican and 2, 4-D + MCPA) in their recommended doses and combined treatment of cycloxydim + (dicamba + tritosulfuron) at their recommended and reduced doses which were used as split and complete application. Results showed that application of combined treatment of cycloxydim + (dicamba + tritosulfuron) with more than 150 g a.i. ha-1 was more effective in weeds control as compared with other herbicide treatments. The highest weed control was observed in cycloxidim application at 300 and 150 g a.i. ha-1 in 3-4 leaf stage of corn plus application of dicamba + tritosulfuron at 100 + 50 g a.i. ha-1 in 5-6 leaf stage of corn, leading to 85% decrease in weed density and biomass. The lowest weed control was observed in Eradican application at the rate of 4.1 kg a.i. ha-1 + 2,4- D + MCPA 1012 g a.i. ha-1 at 5-6 leaves stage of corn, as it led to only 55% weed control. The effect of herbicide application treatments on corn grain yield and biomass were not significant, however the highest and the lowest yield were observed in above mentioned treatments, respectively. It could be concluded that application of cycloxidim in CTM, particularly when sustainable weed management and weed seed bank management and environmental hazards of chemical weed control are concerned, is recommended.   Weed Density Dicamba Nicosulforun Foramsulfuron Tritosulfuron Weed dry weight 2017 8 01 103 115 http://jcpp.iut.ac.ir/article-1-2537-en.pdf 10.18869/acadpub.jcpp.7.2.103

Physical parameters (weight, flesh, skin and color) and chemical parameters (total soluble solids content and acidity) were evaluated using Principal Component Analysis (PCA) and cluster analysis Ward Method. The results indicated a high variability in the set of the evaluated apricot genotypes based on bud break season, fruit and pit weight, harvest season, fruit yield, total soluble solids (TSS), and total acidity. Most of the genotypes had a relatively small fruit size; only four had a fruit weight >39 g. In general, fruits had yellowish skin ground color and cream flesh color. There was a high correlation between fruit and pit weight(r = 0.575), but fruit weight was not correlated with TSS content and acidity. There was a high negative correlation between the TSS and total acidity (r = -0.954). Bud break season was highly correlated with harvest season (r = 0.857). The results indicated the presence of great genetic variability among local genotypes, and there was promising genotypes with appropriate pomological and phenological characteristics.

The use of plant growth regulators has been expanded for improving salt tolerance in recent decades. In this investigation the effect of gibberellic acid (GA) and paclobutrazol (GA inhibitors) were evaluated for ameliorating negative effects of salt stress in sweet sorghum. After germination, the plants in 4 levels of salinity were cultured in Hoagland solution then seedlings were treated by GA and paclobutrazol (PBZ) for 12 days. The results showed that the highest level of salinity without hormone treatment reduced the fresh and dry shoot weight by 44 and 22%, respectively, and increased the fresh (46%) and dry (16%) root weight. Treating Plants with 17 Mm GA and PBZ led to improvement of the above traits in the salt–stricken plants. PBZ treatment decreased negative effects of salinity and increased potassium (K+) content in roots and its transfer from root to shoot. Whereas, translocation factor of sodium was increased about 39% by GA treatment at the presence of 150mM salt. PBZ enhanced phenol content in shoots by increasing PAL activity. Therefore, GA and PBZ improved salt tolerance by transferring some ions toward shoot and root respectively. It seemed that, PBZ has an effective role in salt resistance by increasing of root growth, phenol content and maintaining the ionic balance Plant growth regulators Salt tolerance Ionic balance GA inhibitor PAL TAL 2017 8 01 133 149 http://jcpp.iut.ac.ir/article-1-2586-en.pdf 10.18869/acadpub.jcpp.7.2.133
