  Citrus is a major product of the gardens of the north of the country, and since oranges have better storage, they also have a larger share of the gardens. Oranges have a very good market and have a good market and have the highest production, but because it has thin navel and skin, it is sensitive to tension and has a physiological disorder Fruiting. In order to reduce this complication, a randomized complete block design with 2 and 4 dichlorophenoxy acetic acid (2, 4-D) at concentrations of 0-10 and 20 mg / L and gibberellic acid GA3 (with concentrations of 0- 50 and 100 mg / L at flowering time, petals fell immediately after the physiological fall of fruit for two consecutive years (2016-2017). In this experiment, the percentage of fruit grazing, fruit yield, fruit skin thickness, soluble solids, cellulase and superoxide dismutase enzyme activity were measured. Based on the results obtained from the comparison of the meanings, the maximum thickness of the fruit skin, soluble solids, performance and activity level of the enzyme superoxide dismutase, as well as the lowest activity of the enzyme cellulase Manuscript profile

   هدف از این مطالعه بررسی اثرات سطوح مختلف تنش شوری و محلول­پاشی 6-بنزیل آمینوپورین (بنزیل آدنین) بر ویژگی‌های مورفولوژیک و بیوشیمیایی یاسمن زمستانه بود. بنابراین آزمایشی در سال‌های 96-1395 در مرکز تحقیقات گلخانه‌ای دانشگاه آزاد اسلامی واحد اصفهان (خوراسگان) انجام شد. این آزمایش بصورت فاکتوریل بر اساس طرح کاملا تصادفی با چهار سطح تنش شوری (2، 4، 6 و 8 دسی‌زیمنس بر متر) به‌عنوان عامل اول و سطوح مختلف بنزیل‌آدنین (کنترل (عدم کاربرد)، 25 و 50 میلی‌گرم در لیتر) به عنوان عامل دوم در 3 تکرار (مجموع 36 واحد آزمایش) انجام شد. صفاتی مانند وزن تر و خشک وزن گل، تعداد گل، درصد کلروفیل a، b، کل، کاروتنوئید و آنزیم سوپراکسید دیسموتاز گیاه یاسمن زمستانه مورد مطالعه قرار گرفت. نتایج نشان داد که سطوح شوری و بنزیل‌آدنین تاثیر معنی‌داری بر تمام صفات داشت. نتایج نشان داد که فعالیت آنزیم سوپر اکسید دیسموتاز در شوری هشت دسی‌زیمنس بر متر به‌طور معنی‌داری از فعالیت این آنزیم در تیمار دو دسی‌زیمنس بر متر بیشتر بود و بالاترین فعالیت آن در تیمار هشت دسی‌زیمنس بر متر مشاهده شد. از سوی دیگر، در بررسی اثرات استفاده از بنزیل‌آدنین، مشاهده شد که این تیمار اثرات مثبتی بر تمام صفات مورد بررسی دارد و اثرات آن­ها وابسته به غلظت است. در پایان می‌توان گفت، با وجودی که تنش شوری اثر منفی بر یاسمن زمستانه داشت، تیمار بنزیل‌آدنین اثرات منفی تنش شوری را کاهش داده است.

  This study was conducted to evaluate the effect of auxin and cytokinin spraying in different growth stages on grain composition of maize (KSC 704) under drought stress condition during 2013 growing season at Seed and Plant Improvement Institute, Karaj, Iran. The experiment was carried out in three separate environments included non-drought stress environment, drought stress in the vegetative stage and drought stress in the reproductive stage. In each environment, foliar application of cytokinin in three stages (control, V5 –V6 and V8-V10) and foliar application of auxin in three stages (control, silk emergence and 15 days after that) was laid out as a factorial design based on randomized complete block design with three replications. The results showed that the maximum protein (10.93%) and soluble sugar (5.80%) in grain were obtained under drought stress in the productive stage whereas the maximum starch (77.37%) and grain dry mater (90.83%) were obtained in non-stress condition. Foliar application of cytokinin in V8-V10 stage, increased convert starch to soluble sugar on the other hand, foliar application of auxin in silk emergence stage caused converting hexose sugars to starch, increasing the sink capacity (grain endosperm) for receiving more starch and also increasing the grain dry mater .

  In order to investigate the effects of external application time of salicylic acid hormone on morphological and physiological properties of barley (Nosrat cultivar) under stress conditions in Neyriz city during two cropping years 2019-2020 and 2020-2021 a split plot experiment based on randomized complete block design with the main factor of different irrigation conditions (without irrigation, two irrigation and four times of irrigation) and the sub factor of salicylic acid foliar application times (without foliar application, tillering end 50% emergence of stem and end of flag leaf emergence) was conducted. The results showed That without irrigation treatment reduced leaf chlorophyll index and chlorophyll a and b by 74.2%, 66.02 and 42.31%, respectively. without irrigation Treatment also significantly reduced grain yield. It was 86.9% (average of two years of experiment). Foliar application at the end of tillering increased grain yield by 10.36% on average. Increased grain yield due foliar application at the end of tillering in without treatment irrigation was 6.2% and in four times irrigation treatments was 10.1%, which indicates the positive effect foliar application in higher humidity conditions. Foliar application increased the concentration of proline compared to the control without foliar application. The highest proline concentration was foliar application at the end of tillering. Proline concentration increased with decreasing irrigation frequency. The results indicate application of salicylic acid at the end of tillering by improving biochemical properties is effective in reducing the effects of drought stress and its use in barley is recommended in similar water and soil conditions.

  When the plant is exposed to abiotic stresses, the cell membrane is the first part of the cell to be affected by stress, and the relationships of the many of physiological and biochemical cell of the plant are disrupted. The effect of three growth hormones (3 indoleacetic acid [IAA], gibberellic acid [GA3] and 6 benzylaminopurine [6 BAP]) with a control (distilled water) was evaluated at booting stage of two wheat cultivars (Rijaw and Azar 2). A factorial experiment using a randomized complete block design (RCBD) with three replications was setup at Campus of Agriculture and Natural Resources, Razi University, Kermanshah, Iran in 2013-14 and 2014-15. Based on the results, the effect of different growth hormones on SPAD, relative water content, Fv/Fm, performance index, leaf cell membrane stability and photosynthetic rate of both cultivars were significant. Among growth hormones, foliar application of Cytokinin and Auxin had the greatest effect on the measured leaf traits and the lowest mean of the traits was obtained in non-spraying treatment (control). Between the two cultivars, Rijaw cultivar was superior to Azar-2. There was also a positive and significant correlation between cell membrane stability and photosynthesis rate, Fv/Fm and performance index. In general, in dryland conditions (water deficiency) with external application of cytokinin in booting stage in superior wheat cultivar (Rijaw) cell membrane stability, relative water content, photosynthetic rate and Fv/Fm were 16, 18, 38 and 45 percent higher than the control, respectively.
