چکیده

به منظور بررسی اثر پیش­تیمار بذر با نانو کلات آهن و سالیسیلیک اسید بر خصوصیات جوانه­زنی و رشد عدس تحت تنش شوری، آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار انجام شد. تیمارهای آزمایش شامل پیش­تیمار با سالیسیلیک اسید و نانو کلات آهن هر کدام در سه سطح شامل 1000، 2000 و 3000 میلی­گرم بر لیتر، پیش­تیمار با آب مقطر و شاهد (بدون اعمال پیش­تیمار) و چهار سطح شوری شامل شاهد، 1000، 2000 و 3000 میلی­گرم بر لیتر بود. نتایج نشان داد که اثر پیش­تیمار با نانو کلات آهن و سالیسیلیک اسید در شرایط شوری بر درصد و سرعت جوانه­زنی، درصد و سرعت سبز شدن، میانگین مدت زمان جوانه­زنی و سبز شدن، طول ساقه­چه، وزن تر و وزن خشک ساقه­چه در سطح احتمال 1% معنی­دار بود. غلظت 3000 میلی­گرم بر لیتر کلرید سدیم سبب کاهش معنی­دار شاخص­های جوانه­زنی و رشد گیاهچه نسبت به شاهد گردید. در کل، سالیسیلیک اسید نسبت به نانو کلات آهن اثر مثبت بیشتری بر شاخص­های جوانه­زنی و رشد گیاهچه عدس در شرایط تنش و بدون تنش شوری داشت و با کاربرد سالیسیلیک اسید به تنهایی و تحت تنش شوری شاخص­های جوانه­زنی و رشد گیاهچه نسبت به شاهد افزایش یافت. بنابراین پیش­تیمار بذر با سالیسیلیک اسید 3000 میلی­گرم بر لیتر موجب بهبود جوانه­زنی و استقرار گیاهچه در شرایط شوری و بدون شوری می­شود.

چکیده [English]

To study the effect of seed priming by salicylic acid and nano-iron chelate on germination and initial growth of lentil under salinity stress, a factorial experiment was conducted based on completely randomized design with three replications. Treatments was contained priming with salicylic acid and nano-iron chelate each with three levels (1000, 2000 and 3000 mg.L-1), hydropriming with distilled  water and control (non-priming) and four salinity levels (control, 1000, 2000 and 3000 mg.L-1). The results showed that seed priming by salicylic acid and nano-iron chelate had significant effect on germination percentage and rate, emergence percentage and rate, mean of germination and emergence time mean, plumule length, fresh and dry weight under salinity stress. The sodium chloride salt with 3000 mg.L-1 rate caused significant decrement in seedling germination and initial growth characteristics, comparing to control. In the present study, salicylic acid showed positive effect on germination and growth characteristics of lentil seedling under salinity stress with and without nano-iron chelate, so that germination and initial growth characteristics of lentil seedling were increased by application of salicylic acid in sole and under salinity stress, comparing to control. Therefore, applying seed priming by salicylic acid with 3000 mg.L-1 to improve germination and establishment of seedling with or without salinity stress condition is going to be recommended.
