| چکیده | ||
| به منظور بررسی اثر مگنتوپرایمینگ بر جوانه زنی بذرکنجد تحت شرایط تنش خشکی، آزمایشی بصورت فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار در سال 1393 در دانشگاه فردوسی مشهد اجرا شد. بذور خشک کنجد به صورت توده ای در معرض میدان های مغناطیسی (شاهد (عدم قرار گیری)، 25 میلی تسلا به مدت 10 دقیقه و 75 میلی تسلا به مدت 60 دقیقه) قرار گرفته و سپس با پلی اتیلن گلیکول 6000 با پتانسیل های مختلف (شاهد (آب مقطر)، 2-، 4-، 6- و 8- بار) تیمار شدند. در نهایت صفاتی نظیر درصد جوانه زنی، سرعت جوانه زنی، طول ساقه چه و ریشه چه، وزن خشک ساقه چه و ریشه چه و نیز شاخص های طولی و وزنی بنیه گیاهچه ثبت شد. نتایج نشان داد که پرایمینگ با میدان های مغناطیسی منجر به افزایش سرعت جوانه زنی، طول ریشه چه، طول ساقه چه، وزن خشک ریشه چه و شاخص های طولی و وزنی بنیه گیاهچه مخصوصاً در شدت های بالای تنش خشکی نسبت به تیمار شاهد (عدم پرایمینگ) شد. طول ریشه چه برای بذور پرایم شده با میدان مغناطیسی 75 میلی تسلا به مدت یک ساعت در تنش 8- بار، 16.6 درصد و وزن خشک ریشه چه در همین سطح از تنش و در بذور تیمار شده با میدان 25 میلی تسلا به مدت 10 دقیقه حدود 64.4 درصد نسبت به تیمار شاهد (عدم قرارگیری) بیشتر بود. همچنین در اثر پرایمینگ با میدان های مغناطیسی 75 و 25 میلی تسلا در پتانسیل 8- بار، شاخص های طولی و وزنی بنیه گیاهچه به ترتیب 38 و 22.6 درصد نسبت به تیمار شاهد افزایش یافتند. | ||

| چکیده [English] | ||
| In order to investigate the effect of magneto priming on seed germination of sesame seed under water stress conditions, a factorial experiment based on a completely randomized design with three replications was carried out in 2014 in Ferdowsi University of Mashhad. Dry seeds of sesame exposed to magnetic fields (control (no priming), 25 mT[1] for 10 minutes and 75 mT for 60 minutes) bulky, then they treated by Polyethylene glycol 6000 (PEG6000) with different potentials (control (distilled water), -2, -4, -6 and -8 bar). Finally, germination traits such as germination percentage, germination rate, plumule and radicle length, dry weight of plumule and radicle and seedling length and seedling weight vigour indices were measured. The results showed that magneto priming led to increment of germination rate, radicle and plumule length, radicle dry weight and seedling length and seedling weight vigour indices, especially in high levels of water stress compared with control treatment. Radicle length of magneto primed sesame seeds with 75 mT (for 60 minutes) in -8 bar was 16.6% and radicle dry weight of magneto primed seeds with 25 mT (for 10 minutes) at the same level of water stress, was 64.4% more than control (no priming). In addition in -8 bar potential, due to priming with 75 and 25 mT intensities of magnetic fields, seedling length and weight vigour indices enhanced 38% and 22.6%, respectively, in comparison to control treatment.
