| پژوهش حاضر با هدف ارزیابی اثر نانوپرایمینگ با استفاده از نانولولههای کربنی چند جداره بر تحمل به تنش خشکی بر گونه توسکای ییلاقی انجام گرفت. این مطالعه به صورت آزمایش فاکتوریل در قالب طرح کاملاً تصادفی با 4 تکرار انجام شد. با استفاده از محلول پلیاتیلن گلایکول 6000 در سطوح 0، 2-، 4-، 6- و 8- بار تنش خشکی در آزمایشگاه بر روی بذرهای پرایم شده با غلظتهای 0، 10، 30، 50 و 100 میلیگرم بر لیتر نانولولههای کربنی اعمال شد. نتایج نشان داد اثر نانو پرایمینگ و تنش خشکی بر روی شاخصهای درصد جوانهزنی، سرعت جوانهزنی، وزن تر ریشه، وزن تر ساقه و نسبت وزن تر ریشه به ساقه در سطح احتمال 99% معنیدار است. در تمام سطوح تنش خشکی، بالاترین درصد و سرعت جوانهزنی در تیمار 100 میلیگرم بر لیتر نانوکربن مشاهده شد. همچنین بیشترین وزن تر ریشه و ساقه در تمام سطوح خشکی متعلق به تیمار 30 میلیگرم بر لیتر نانوکربن بود. با توجه به نتایج به دست آمده از این تحقیق میتوان نتیجه گرفت که نانو پرایمینگ با نانولوله های کربنی چندجداره موجب بهبود صفات جوانهزنی بذر درخت توسکا در شرایط تنش خشکی خواهد شد. | ||

| Current research aimed to evaluate the effect of nano priming using multi-walled carbon nanotubes on drought tolerance of Caucasian alder. This study was employed a factorial experiment in a completely randomized design with four replications. Drought stress was applied in the laboratory, using a solution of polyethylene glycol 6000 at 0, -2, -4, -6, and -8 bar on the primed seeds with concentrations of 0, 10, 30, 50 and 100 mg l-1 of carbon nanotubes. The results showed significant effect of nano priming and drought stress on germination factors such as germination rate and percentage, root fresh weight, shoot fresh weight and root to shoot fresh weight at the probability of 99%. The highest germination rate and percentage at all levels of drought stress, was related to100 mg l-1 of nano carbon treatment. The highest fresh weight of root and shoot at all levels of drought stress was related to 30 mg l-1 of nano carbon treatment. According to the results of this experiment it could be concluded that nano-priming improve seed germination characteristics of alder tree under drought stress. | ||
