| چکیده | ||
| این مطالعه با هدف بررسی اثر هیدروپرایمینگ بر خصوصیات جوانهزنی و ظهور گیاهچه ذرت در شرایط کنترل شده بهصورت آزمایش فاکتوریل برپایه طرح کاملاً تصادفی با دو ذرت هیبرید سینگلکراس704 و کرج 700 و 6 زمان خشک کردن صفر، 5/1 ،3 ،6 ، 12و 24 ساعت و تیمار شاهد (بدون پیشتیمار) بذرها بعد از 17 ساعت خیساندن با 3 تکرار انجام شد. از لحاظ اکثر صفات اندازهگیری شده هیبریدهای مورد بررسی تفاوت معنیداری داشتند و هیبرید کرج 700 خصوصیات جوانهزنی و ظهور گیاهچه مطلوبتری نسبت به سینگلکراس 704 داشت. با اعمال پیشتیمار، متوسط زمان جوانهزنی بذرهای پیشتیمار شده نسبت به شاهد کاهش و متوسط سرعت جوانهزنی آنها افزایش معنیداری (05/0≤P (را نشان داد، بهطوری که بذرهایی که به مدت 3 ساعت خشک شده بودند دارای بالاترین متوسط سرعت جوانهزنی (5/1 برابر شاهد) بودند. طول و وزن خشک ریشهچه و ساقهچه بذرهای پیشتیمار شده نسبت به شاهد افزایش معنیداری (05/0≤P (داشتند. با وجود اثرات مثبت هیدروپرایمینگ بر خصوصیات جوانهزنی نظیر کاهش متوسط زمان جوانهزنی، افزایش متوسط سرعت جوانهزنی، افزایش طول و وزن خشک ریشهچه و ساقهچه در گیاه ذرت، هیچیک از پیشتیمارها تأثیر معنیداری بر خصوصیات گیاهان رشد یافته در گلخانه نداشتند. | ||

| The effect of seed hydropriming on germination and seedling growth of maize (Zea mays L.) in controlled condition | ||
| چکیده [English] | ||
| In order to evaluate the effect of maize seed priming in germination and emergence stage in controlled condition, an experiment was conducted as factorial on the basis of completely randomized design with two maize hybrids (S.C.704 and Karaj 700) and six time of seeds dry back after 17 hours wetting (0,1.5,3,6,12 and 24 hours and control treatment (without priming)) with three replications. There were significant differences (Pandlt;%5) between two hybrids for most of the parameters, and germination and emergence of Karaj 700 was higher than S.C.704. Priming decreased mean germination time (MGT) of primed seeds to control and also mean germination rate (MGR) of seeds increased significantly. Seeds that 3 hours dried back had the highest MGR. Radicle and plumule length and radicle and plumule dry weight of primed seeds was higher than the control.Although priming had positive effects on characteristics such as decrease in MGT, increase in MGR, in length and dry weight of radicle and plumule, none of priming treatments had significant effects on grown plant characteristics in glasshouse. | ||
