| چکیده | ||
| زوال یا پیری به عنوان یکی از عوامل کاهش دهنده بنیه و محدودکننده‌ی جوانه‌زنی بذر می‌باشد. انبارداری نامناسب در محل‌های ذخیره‌سازی مخصوصا بانک‌های ژن می‌تواند سبب تسریع فرایند پیری در انواع بذور شود. در این مطالعه به منظور بهبود اثرات نامطلوب حاصل از زوال بذر، تاثیر تیمار هورمونی با اسیدجیبرلیک، سیتوکنین، اکسین و اسید سالیسیلیک در غلظتهای صفر، 50، 100 و 150 میکرولیتر بر کیفیت بذرهای زوال یافته طبیعی و مصنوعی گندم به صورت آزمایشگاهی در آزمایشگاه های بذر پردیس کشاورزی و منابع طبیعی دانشگاه تهران در سال 1395 مورد بررسی قرار گرفت. پس از تیمار هورمونی، جوانه زنی بذرها تحت شرایط تنش شوری در سه سطح صفر، 4- و 8- بار بررسی شد. نتایج نشان داد بذور طبیعی پیر شده در تمام صفات مشاده شده میانگین بالاتری را داشتند.در میان هورمون‌های گیاهی هورمون سیتوکنین در صفات درصد و سرعت جوانه‌زنی و شاخص جوانه‌زنی بیشتری را نشان داد. غلظتهای هورمونی نسبت به تیمار شاهد (آب مقطر) در تمام صفات بهتر عمل کرده و سبب افزایش تحمل تنش شوری شده است. تنش شوری توانست تمام صفات به جز متوسط زمان جوانه‌زنی را تحت تاثیر قرار دهد. | ||

| Dehydration or Aging is one of the vigor reducing and seed germination limiting agents. Inappropriate storage places, especially the gene banks, can speed up the aging process in a variety of seeds. In this study, to improve the adverse effects of seed aging, hormone treatments with GA, Cytokinin, Auxin and Salicylic acid in concentrations of 50, 100 and 150 ppm (and distilled water as a control) on the quality of the naturally and synthetic deteriorated seeds of wheat were studied in the seed laboratory of Agriculture and natural resources college, Tehran University in 2015. After hormonal treatment, germination under salt stress in three levels, 0, -4 and -8 bar were investigated. The results showed that the naturally aged seeds had a higher mean value for all the traits. Treatment with cytokinin hormone showed higher percentage and germination rate and WGI between others hormones and all the hormonal treatments were better than control treatment (distilled water) in all traits and increased salinity stress tolerance. Salinity stress could affect all traits except the Mean Germinations Time. | ||
