This research was conducted at the Behbahan Agriculture Research Station, Behbahan, south-west of Iran, for two years from 2016 to 2018 to study the postharvest losses of short-day onion cultivars in uncontrolled storage conditions (no heating, cooling and ventilation systems). Seeds were sown in nursery in early October and seedling transplanted at 2-3 leaf stage. Bulbs were harvested when 50-80% of foliage had dried and fallen and prepared for the experiment in both years. In the 1st year of experiment, the average of daily storage temperature and relative humidity ranged from 14.5 to 40.5°C and 27 to 60%, respectively. The average of daily storage temperature and relative humidity varied from 15 to 38 °C and 30 to 71%, respectively, in the 2nd year of experiment. This research was performed using a split plot experiment based on a randomized complete block design encompassing 80 treatments with 4 replications. Main plot consisted of 10 cultivars (‘Seba’, ‘Texas Early White’, ‘Imperateriz’, ‘Siroos’, ‘7030’, ‘X P red’, ‘Sapidan’, ‘Golden I’, ‘Texas Early Grano’ and ‘Primavera’) and bulbs evaluation in storage at eight times (one months after start of storage with one month interval) was considered as sub plot. The monthly bulb weight losses percentage decreased with time. The minimum weight loss (9.56%) was recorded in ‘Seba vultivar. The damage of black mold increased until the fourth month of storage and then decreased. ‘Sapidan’ was the most sensitive cultivar to damage of black mold (23.23%). The highest percentage of bulb rotting (29.65%) was observed in ‘Texas Early White’ cultivar. Bulb sprouting was observed from the fifth month of storage and the highest bulb sprouting (19.88%) belonged to ‘Siroos’ cultivar. Results were suggestive of difference in storability among cultivars, the maximum and minimum storability being recorded in ‘Seba’ and ‘Sapidan’, cultivars, respectively.
该研究于2016年至2018年在伊朗西南部Behbahan农业研究站进行，为期两年，研究短日照洋葱品种在无控制的储存条件下(无加热、冷却和通风系统)的采后损失。10月初苗圃播种，2 ~ 3叶期移栽。球茎收获时，50-80%的叶片已经干燥和下降，并准备在这两年的实验。试验第一年的日平均贮藏温度和相对湿度分别为14.5 ~ 40.5°C和27% ~ 60%。试验第二年的日平均贮藏温度和相对湿度分别为15 ~ 38℃和30 ~ 71%。本研究采用基于随机完全区组设计的分割图试验，包括80个处理，4个重复。主区由‘Seba’、‘Texas Early White’、‘Imperateriz’、‘Siroos’、‘7030’、‘X P red’、‘Sapidan’、‘Golden I’、‘Texas Early Grano’和‘Primavera’10个品种组成，分8次(开始储存后1个月，间隔1个月)进行球茎储存评估。月球茎失重率随时间而降低。减重最小的品种为阴Seba，为9.56%。贮藏第4个月，黑霉的危害呈上升趋势，之后又呈下降趋势。对黑霉危害最敏感的品种为“沙匹丹”(23.23%)。“德州早白”品种球茎腐烂率最高，达29.65%。从贮藏第5个月开始球茎出芽，‘Siroos’品种球茎出芽率最高，达19.88%。结果表明，不同品种的贮藏性存在差异，‘Seba’和‘Sapidan’的贮藏性分别最高和最低。

To investigate adoptability and pattern of G × E interaction, 15 faba bean lines as well as four check cultivars (including Barekat, Saraziri, Baloochi and Zereshki) were evaluated using a randomized complete block design with three replications in four agricultural research field stations of Gorgan, Dezful, Brojerd and , Iranshahr, Iran during two cropping seasons (2015-2016 and 2016-2017). Combined analysis of variance showed significant effects of location, year, year × location interaction, genotype × location interaction, genotype × year interaction and year × location × genotype interaction on grain yield. Stability in performance of the 19 genotypes was tested using GGE-Biplot approach across eight environments. GGE- Biplot analysis using a genotype × environment interaction (GEI) model explained 91.5% of total interaction effect variance. View of polygon graph revealed three superior mega-environments and the compatible genotypes were determined for each mega-environment; Gorgan (Line G15), Brojerd-Iranshahr (Line G3) and Iranshahr (Line G19). Lines G15, G7 and G13 with average seed yield of 3439, 3128 and 3094 kg ha -1 , respectively, had higher seed yield and yield stability. Based on GEI and GGE- Biplot analysis, Gorgan and Brojerd experimental environments had good differentiation ability. Finally, genotypes G12, G14 and G15 were the most stable genotypes with wider adaptation to all the tested environments and can be recommended as the superior genotypes for being released as new commercial faba bean cultivars.
为了研究G × E互作的可采性和模式，在2015-2016和2016-2017两个种植季，在伊朗Gorgan、Dezful、Brojerd和Iranshahr四个农业研究现场站，采用3个重复的随机完全区组设计，对15个蚕豆品系和4个对照品种(Barekat、Saraziri、Baloochi和Zereshki)进行了评价。综合方差分析表明，位置、年份、年×位置互作、基因型×位置互作、基因型×年份互作和年×位置×基因型互作对籽粒产量影响显著。使用ge - biplot方法在8种环境中测试了19个基因型的性能稳定性。使用基因型×环境相互作用(GEI)模型的GGE-双图分析解释了91.5%的总相互作用效应方差。多边形图显示了三个优越的大环境，并确定了每个大环境的相容基因型;戈尔根(G15线)，布罗杰德-伊朗沙尔(G3线)和伊朗沙尔(G19线)。品系G15、G7和G13的平均种子产量分别为3439、3128和3094 kg ha -1，具有较高的种子产量和产量稳定性。基于GEI和GGE- Biplot分析，Gorgan和Brojerd实验环境具有良好的分化能力。最后，基因型G12、G14和G15是最稳定的基因型，对所有测试环境的适应性较广，可以作为推荐的优良基因型作为新的商业蚕豆品种发布。

In order to investigate the effect of deficit water stress and different combinations of relay intercropping of chickpea with barley on some biochemical traits and grain yield, a field experiment was conducted at College of Agriculture and Natural Resources of Darab, Shiraz University during 2017-2018 cropping season, as split plot based on a randomized complete block design with three replications. Treatments included two irrigation regimes (normal irrigation and cutting off irrigation at milk development stage) as main factor and the 6 combinations of cropping systems consisted of cultivation of barley on December, barley on January, and different combinations of intercropping consisted of barley in December + chickpea in December, barley in December + chickpea in January, barley in January + chickpea in December, and barley in January + chickpea in January with a ratio of 1:1 as sub factor. Results showed that deficit water stress had significant effects on chlorophyll a , catalase and peroxidase activity, leaf relative water content (RWC) and contribution of current photoassimilates to the grain yield of barley and grain yield of chickpea. Under deficit water stress, barley grain yield had a positive correlation with leaf relative water content (R 2 =0.47 )* . Also, under deficit water stress condition, the highest carotenoid content was obtained from intercropping of barley in December + chickpea in January. Since intercropping of barley in December + chickpea in January had the highest carotenoid content , remobilization efficiency, and contribution of current photoassimilates to the grain yield of barley and hence grain yield of barley (4215.7 kg/ha), it may be a suitable cultural strategy to be taken under late season deficit water stress conditions.

Aiming at finding a suitable treatment for maintaining the fruit quality and increase the shelf life of strawberry, effects of ascorbic acid and essential oil of Thymbra spicata were evaluated. Fruits were dipped in 10 and 15 mM of ascorbic acid and essential oil of T. spicata (400 and 600 ppm) for two minutes, and after drying at room temperature, were packed by cellophane in the polyethylene container and transferred to 4 °C. Some of the qualitative, quantitative and biochemical parameters were measured at 7 and 14 days after storage. Results of analysis of variance showed that there were significant differences among the treatments in most of the evaluated parameters. Strawberry fruits treated with ascorbic acid and essential oil showed lower weight loss and lower fruit browning, while they had higher marketability than control plants. Ascorbic acid and essential oil treatments also led to decreases in polyphenol oxidase activity, total phenol content and electro leakage, while the vitamin C content and antioxidant capacity were significantly higher than control plants. Generally, ascorbic acid (15 mM) and essential oil (400 ppm) compounds reduced fruit’s degradation during cold storage and these treatments have the potential to be used as practical postharvest treatments to retain the quality of strawberry fruits.

Emmer tetraploid hulled wheats are considered as the ancestor of modern wheat and have considerable potential for durum wheat improvement, especially in terms of grain protein content. To investigate the response of emmer and durum wheats to different levels of nitrogen fertilizer, eight durum and four emmer genotypes were evaluated in the field during 2017 cropping season. The experiment was conducted as split plot using randomized complete block design with three replications. In this setting the main factor was four levels of urea fertilizer (0, 50, 150 and 200 kg ha -1 ) and the 12 wheat genotypes were considered as the sub-factors. The results of analysis of variance showed that the effect of nitrogen fertilizer levels on days to physiological maturity, grain protein percentage, nitrogen percentage and nitrogen concentration in grains was significant (p<0.01). The effect of genotype was also significant (p<0.01) for all the measured traits. Emmer genotypes had higher means for spike number per square meter, grain protein, nitrogen concentration in grain and protein percentage compared to durum wheat genotypes. Based on these findings, emmer wheat can be considered as a rich gene resource for improvement of durum wheat, especially the grain protein.
二聚四倍体有壳小麦被认为是现代小麦的祖先，在硬粒小麦改良方面具有相当大的潜力，特别是在籽粒蛋白质含量方面。为了研究二粒小麦和硬粒小麦对不同氮肥水平的响应，在2017年种植季对8个硬粒小麦和4个二粒小麦基因型进行了田间评价。试验采用随机完全区组设计，设3个重复。在本试验条件下，主要因子为4个水平(0、50、150和200 kg ha -1)的尿素施用量，12个小麦基因型作为子因子。方差分析结果表明，施氮肥水平对生育期至生理成熟期、籽粒蛋白质率、氮素率和籽粒氮浓度的影响极显著(p<0.01)。基因型对各性状的影响也极显著(p<0.01)。与硬粒小麦基因型相比，Emmer基因型在每平方米穗数、籽粒蛋白质、籽粒氮浓度和蛋白质百分比方面具有较高的平均值。综上所述，二粒小麦可作为硬粒小麦改良的丰富基因资源，尤其是籽粒蛋白质改良。

Using of nitrogen fertilizers may increase the photosynthesis and yield of crop plants. Hence, we investigated the effect of chemical nitrogen and rhizobium fertilizers on the photosynthesis and yield components of red beans (Sayad cultivar) in an experiment as a randomized complete block design with 4 replications in Al-Mahdi town, Azna, Iran. The treatments included zero (control), 100 and 200 kg ha -1 of urea and rhizobium, and rhizobium + 30 and 50 kg ha -1 of urea. The results of this experiment showed that the effect of fertilizer treatments was significant on leaf area index, level, efficiency and contribution of current photosynthesis, level, efficiency and contribution of remobilization, dry weight in pre-flowering and maturing stages and grain yield and its components. The chemical fertilizer and rhizobium application increased the amount of all the above traits except for the contribution of current photosynthesis. There was a strong correlation between grain yield and the level, efficiency and contribution of current photosynthesis and the level, efficiency and contribution of current of remobilization. The examined wide range of nitrogen fertilizers were potent to increase the photoassimilates production and, hence, yield and yield components of red bean in this region.
施用氮肥可以提高作物的光合作用和产量。为此，我们在伊朗Azna Al-Mahdi镇采用4个重复的随机区组设计，研究了化学氮肥和根瘤菌肥对红豆(Sayad品种)光合作用和产量组成的影响。无(对照)、100和200 kg / h尿素和根瘤菌+ 30和50 kg / h尿素处理。本试验结果表明，施肥处理对水稻叶面积指数、当前光合作用水平、效率和贡献率、再活动水平、效率和贡献率、花前期和成熟期干重、籽粒产量及其构成因素均有显著影响。施用化肥和根瘤菌对除光合作用贡献外的其他性状均有提高作用。籽粒产量与当前光合作用水平、效率和贡献以及再动员电流水平、效率和贡献之间存在较强的相关关系。结果表明，大范围施用氮肥能有效提高赤豆光合产物的产量，从而提高赤豆的产量和产量组成。

To evaluate drought tolerance in faba bean genotypes, 21 genotypes were studied in a randomized complete block design with three replications under normal irrigation and drought stress conditions. The experiment was conducted in 2017-2018 at research station of Gorgan, Iran. Indices such as stress tolerance index (STI), stress susceptibility index (SSI), tolerance (TOL), mean productivity (MP), geometric mean productivity (GMP), yield index (YI) and yield sustainability index (YSI) were calculated for all genotypes according to grain yield in normal irrigation and stress conditions. Based on analysis of variance results, there was a significant difference among the genotypes in terms of grain yield in both environments (normal irrigation and drought stress). The results of correlation showed that STI, MP, GMP and TOL are suitable for selection of high-yielding genotypes in both environments, among which STI and MP were the most suitable indices to select drought-tolerant genotypes. Based on STI, MP and GMP indices, GF-65 genotype was classified drought-tolerant, and GF-525 and GF-21 were susceptible according to TOL and SSI indices. Results of cluster analysis showed that GF-66, GF-62, GF-75 and GF-67 were superior compared to other genotypes based on YSI, YI, GMP, MP and STI indices, and utilization of these genotypes may be recommended to achieve high yields in drought stress conditions.
