| چکیده | ||
| به‌منظور بررسی تأثیر رطوبت بذر در زمان برداشت و اعمال پیش تیمارهای بذری بر وضعیت قوه نامیه بذر و رشد گیاهچه های جو در یک دوره انبارداری مشخص، آزمایشی در مؤسسه تحقیقات ثبت و گواهی بذر و نهال کرج در سال92-1391 انجام گرفت. تیمارها شامل سه سطح رطوبتی14، 16 و 18% بذر در زمان برداشت پس از رسیدگی فیریولوژیکی و پیش تیمارهای بذری با محلول های پوترسین، اسپرمیدین، اسپرمین و آب بعد از یک دوره هشت ماهه انبار داری بودند. از بذرهای بدون پیش تیمار نیز به عنوان شاهد استفاده گردید. داده‌ها جهت ارزیابی صفات بعد از برداشت و همچنین بعد از هشت ماه انبارداری، به صورت طرح کاملاً تصادفی مورد تجزیه و تحلیل قرار گرفتند . بعلاوه بذرها بعد از پیش تیمار با انواع پلی آمین‌ها و یک ماه انبار داری مجدد، به صورت فاکتوریل با طرح پایه کاملاً تصادفی مورد تجزیه و تحلیل قرار گرفتند. در ارزیابی بذرها بعد از برداشت، بذرهایی که زودتر برداشت شده بودند (با رطوبت 18 %)، دارای قوه نامیه، درصد جوانه زنی و بنیه بهتری در مقایسه با بذرهایی بودند که دیرتر و با رطوبت 14 % برداشت شده بودند که این روند بعد از هشت ماه انبار داری نیز به همین ترتیب تکرار شد و بذرهایی که دارای برتری بودند از هدایت الکتریکی (نشت الکترولیت) کمتری نیز برخوردار بودند. پیش تیمار کردن بذرها با پلی آمین ها موجب بهبود قوه نامیه، درصد جوانه زنی، تسریع در جوانه زنی و کاهش نشت الکترولیت ها در بذرهای برداشت شده در سه زمان با رطوبت های 14، 16 و 18 در مقایسه با شاهد گردید. حداکثر درصد جوانه زنی با میانگین 98/75 در رطوبت 18 % به همراه اسپرمین به دست آمد، به طوری که این تیمار نسبت به شاهد موجب افزایش 16/86% در جوانه زنی و 18/26 % در قوه نامیه گردید. بذرهایی که زودتر با رطوبت‌های 18و 16 % برداشت شده بودند، بنیه بهتری در مقایسه با بذرهایی که دیرتر و با رطوبت 14 % برداشت شده بودند، داشتند. | ||

| چکیده [English] | ||
| This study was conducted to investigate the role of polyamines (PAs) as priming agents on improving seed vigour with different moisture content (Mc)(14,16,18%) under storage conditions in barley (Hordeum vulgare L.) c.v Usef. Experiments were conducted at the Seed and Plant Certification and Registration Research Institute 1n 2012 -2013. The seeds were hand harvested at three initial moisture contents including 18, 16, 14% using wet weight basis. The seed samples then were sealed in polythene bags and stored in conditioned storages and for 8 months. After that for seed priming, seeds were soaked in 20mg/L-1 (w/v) aerated solution of Spermine (Spm), Puterscine (Put), and Spermidine (Spd) and distilled water (W) for 16h at 20±2C°. After each treatment, seeds were dried to original moisture level in forced air and sealed in polythene bags, stored in a conditioned storage again for one month. Experimental units were arranged as a completely randomized design with four replications after harvesting time and one month conditioned storage after treatment. The result indicated that 18% MC improved the germination percentage and seedling vigour compared to 16 and 14 % MC. Also after 8 month storage, 18% Mc had the highest germination percentage and seedling vigour. The electrolyte leakage decreased in seeds with 18% MC compared to 16 and 14% MC. Also seed treatments significantly increased the seed viability and germination percentage, whereas, mean germination time and electrical conductivity were reduced in all seed treatments. Meanwhile, maximum germination percentage was detected for seed Spm seed treatment and 18% MC. Generally by decreasing moisture content of seed and delay in harvesting time, seedling vigour decreased and the optimum moisture content and seed treatment were 18% and Spm, respectively. | ||
