| چکیده | ||
| این آزمایش به‌منظور بررسی تأثیر نانو ذره‌ی دی‌اکسید سیلیس بر بهبود جوانه‌زنی بذور سویا (رقم ویلیامز) زوال یافته به‌صورت فاکتوریل در قالب طرح کاملا تصادفی در سه تکرار در سال 1394 در آزمایشگاه علوم و تکنولوژی بذر دانشگاه شاهد تهران اجرا شد. عامل اول سطوح مختلف پیری تسریع شده شامل شاهد (بدون زوال بذر) و پیری تسریع شده به‌مدت 24 و 48 ساعت در رطوبت اشباع و دمای 41 درجه سانتی‌گراد و عامل دوم غلظت‌های مختلف نانو سیلیس شامل صفر (شاهد)، 40 و 60 پی‌پی‌ام بود. در این آزمایش صفاتی همچون درصد جوانه‌زنی، سرعت جوانه‌زنی، میانگین مدت جوانه‌زنی، تعداد گیاهچه عادی، وزن تر گیاهچه، نسبت وزنی ریشه‌چه به ساقه‌چه، محتوای نسبی آب ساقه‌چه، طول گیاهچه و میزان کلروفیل برگ اندازه‌گیری شد. نتایج نشان داد که اثر پیش تیمار نانو سیلیس بر تمامی صفات جوانه‌زنی بذور سویا معنی‌دار بود. اما اثر متقابل پرایمینگ نانو سیلیس بر بذور زوال یافته سویا تنها در برخی از شاخص‌های جوانه‌زنی اندازه‌گیری شده اثرگذار بود؛ پیش تیمار 60 پی‌پی‌ام نانو ذره‌ی سیلیس با افزایش 20 درصد سرعت جوانه‌زنی بذور زوال یافته، کاهش میانگین مدت زمان جوانه‌زنی و پیش تیمار 40 پی‌پی‌ام با افزایش حدود 7-10 درصد تعداد گیاهچه عادی و در کل تیمار نانو سیلیس با جبران میزان کلروفیل برگ سبب بهبود جوانه‌زنی بذور زوال یافته شد. | ||

| چکیده [English] | ||
| The experiment was conducted to examine the effects of nano-particle silicon dioxide to improve germination of deteriorated soybean seeds (Williams). The experiment was done as factorial in a completely randomized design with three replications in 2015 in Seed Technology Laboratory in the University of Shahed. The first factor involves different levels of accelerated aging including control and accelerated aging for 24 and 48 hours at 41 ° C in high humidity conditions and different concentrations of nano-silica as the second factor including zero (control), 40 and 60 ppm, respectively. The traits such as germination percentage, germination rate, the average duration of germination, the number of normal seedlings, seedling fresh weight, root to shoot ratio, relative water content of root, seedling length and chlorophyll content were measured. The results showed that the effect of nano-silica pre-treated soybean seed germination was significant on all traits. But the interaction of nano-silica priming and the deteriorated seeds of soybean was significant only in some germination characteristics. Pre-treatment of 60 ppm nano-particle silica increased 20% of deteriorated seeds germination rate and reduced the average time of germination. Pre-treatment of 40 ppm increased about 7-10% of the number of normal seedlings, and also treatment of silica nanoparticles improved seed germination with compensate amount of chlorophyll in deteriorated seeds. | ||
