چکیده مقاله :
به منظور بررسی اثر پیش تیمارهای مختلف بر خصوصیات جوانه زنی و دانه رست ذرت هیبرید سینگل کراس SC704، آزمایشی به صورت طرح بلوک های کامل تصادفی با سه تکرار در آزمایشگاه مرکز تحقیقات کشاورزی و منابع طبیعی استان مازندران (ساری) در سال 1389 اجرا شد. تیمارها شامل پرایمینگ با پلی اتیلن گلایکول با غلظت 10 درصد، نیترات پتاسیم با غلظت 5/0 درصد، کلرید پتاسیم با غلظت 2 درصد، آب خالص و شاهد (بدون پرایمینگ) بود. حداکثر سرعت جوانه زنی در محلول اوسموپرایمینگ پلی اتیلن گلایکول با غلظت 10 درصد و هیدروپرایمینگ (آب خالص) بدست آمد. کمترین وزن تر ساقه چه و درصد جوانه زنی برای اوسموپرایمینگ کلرید پتاسیم با غلظت دو درصد حاصل شد. حداکثر شاخص میزان جوانه زنی، میانگین جوانه زنی روزانه و متوسط زمان جوانه زنی با پیش تیمار نمودن توسط شاهد و کلرید پتاسیم با غلظت دو درصد بدست آمد و بیشترین نسبت وزن خشک ریشه چه به ساقه چه با پیش تیمار کلرید پتاسیم با غلظت دو درصد حاصل شد. همچنین بیشترین شاخص وزنی بنیه دانه رست با محلول اوسموپرایمینگ توسط پلی اتیلن گلایکول با غلظت 10 درصد بدست آمد. نتایج این تحقیق نشان داد که میتوان با روش پرایمینگ، جوانه زنی بذر ذرت هیبرید سینگل کراس 704 را بهبود بخشید. در این صورت قدرت اولیه بذر افزایش یافته و در نهایت موجب افزایش درصد و سرعت سبزشدن بذر خواهد شد که ممکن است در عملکرد نهایی مؤثر باشد. طبق نتایج این تحقیق استفاده از محلول پرایمینگ توسط پلی اتیلن گلایکول 6000 (PEG 6000) با غلظت 10 درصد و هیدروپرایمینگ (آب خالص) به مدت 24 ساعت قابل توصیه میباشد.
In order to study the priming effect on germination and seedling characteristics of a single cross corn (SC704), an experiment was carried out as a randomized complete block design (RCBD) with three replications at Agricultural and Natural Resources Research Center, Mazandaran province (Sari) in 2010. Treatments included seed priming with poly ethylene glycol (PEG) at concentration of 10%, potassium nitrate (KNO3) 0.5%, potassium chloride (KCl) 2%, normal water and a control (no priming). The results showed that the maximum germination rate was occurred for a pretreatment with poly ethylene glycol 10% and hydropriming (water). The lowest shoot wet weight and germination rate was obtained for osmopriming of potassium chloride 2%. Maximum germination rate index, average germination time and mean daily germination was observed in the control and osmopriming with KCl 2% and the highest ratio of dry weight R/S was obtained in potassium chloride 2% pretreatment. Also the weighted index of seedling vigor was obtained by seed pretreatment with polyethylene glycol 10%. In conclusion, the results of this study revealed that priming procedure improved seed germination of corn hybrid SC704 and increased seed emergence rate could eventually increase its performance. According to the results, priming by polyethylene glycol 6000 (PEG 6000) 10% and hydropriming (pure water) for 24 hours is recommended.
