| جوانه‌زنی و تولید گیاهچه نقش مهمی در تولید گیاهان زراعی دارند. این مرحله به شدت تحت تاثیر کیفیت بذر قرار می‌گیرد. در این آزمایش اثر پیش تیمار بذر با اسید جیبرلیک و براسینواستروئید در بذرهای زوال یافته گندم (Triticum aestivum. L) مورد بررسی قرار گرفت. آزمایش به صورت فاکتوریل در قالب طرح پایه کاملا تصادفی با سه تکرار در در سال 1395 انجام شد. تیمارهای آزمایش شامل پیری بذر (پیرنشده و پیرشده) و پیش تیمار بذر با اسید جیبرلیک و براسینواستروئید بود. از تیمارهای بدون پرایمینگ و هیدروپرایمینگ به عنوان شاهد استفاده شد. نتایج تجزیه واریانس نشان داد که اثر متقابل پیری تسریع شده در پرایمینگ بر درصد جوانه زنی، طول ساقه چه، نسبت طول ریشه چه به ساقه چه، سرعت جوانه زنی، میانگین جوانه زنی روزانه و شاخص جوانه زنی در سطح احتمال یک درصد و بر طول ریشه چه، سرعت جوانه زنی روزانه و ضریب سرعت جوانه زنی در سطح احتمال پنج درصد معنی دار بود ولی بر طول گیاهچه و میانگین زمان جوانه زنی معنی دار نبود. همچنین نتایج نشان داد که پیری تسریع شده به طور معنی داری پروتئین محلول گیاهچه را کاهش داده و در مقابل سبب افزایش معنی داری در محتوای مالون دی آلدهید، قند محلول و پرولین شد. در این پژوهش بهترین پیش تیمار برای بهبود ویژگی‌های جوانه زنی بذرهای پیر شده و پیر نشده گندم، استفاده از اسید جیبرلیک بود. | ||

| چکیده [English] | ||
| Germination and seedling production have an important role in crop production. This stage is influenced by quality of the seed strongly. Seed priming with gibberellic (GA3 100 ppm) acid and brassinosteroid (BR 100 ppm) on deteriorated wheat (Triticum aestivum. L) seeds were studied. A factorial experiment based on a completely randomized design with three replications was conducted in 2016. Treatments were seed aging (non-aged and accelerated aged) and seed pretreatment with GA3 and BR. No priming and hydro priming also were used as controls. Analysis of variance showed that the interaction of accelerated aging and priming was significant for germination percentage, plumule length, R/P L, germination rate, MDG, and GI; and for radicle length, DGS and CVG at 5% level. However, on the seedling length and mean germination time was not significant. The results showed that accelerated aging significantly reduced the soluble protein in seedlings and in turn caused a significant increase in malondialdehyde, soluble sugar, and proline content. The results showed that, the germination characteristics were improved under GA3 treatment. | ||
