| چکیده | ||
| به منظور ارزشیابی تاثیر هیدروپرایمینگ بر جوانه زنی و شاخصه های رشدی ارقام نخود در شرایط تنش خشکی دو آزمایش جداگانه انجام شد. در آزمایش اول تاثیر هیدروپرایمینگ بر خصوصیات جوانه زنی دو رقم نخود در آزمایشگاه مورد بررسی قرار گرفت. آزمایش دوم در گلخانه انجام شد. در این بخش پرایمینگ بذرها مانند آزمایش اول انجام شد ولی گیاهان تحت تیمارهای خشکی قرار گرفتند. نتایج نشان داد که افزایش مدت خیساندن بذور در آب از شاهد به 24 ساعت، توانست درصد جوانه زنی را 8 درصد و سرعت جوانه زنی را 25 درصد افزایش دهد. پرایمینگ بذور سبب افزایش طول ریشه چه و ساقه چه در هر دو رقم شد ولی رقم MCC510 دارای طول ریشه چه و ساقه چه بالاتری نسبت به رقم ILC 6266 بود. همچنین با افزایش مدت زمان هیدروپرایمینگ به 24 ساعت در رقم ILC 6266 و MCC 510 شاخص بنیه طولی بذر به ترتیب 41 و 52 درصد نسبت به شاهد افزایش داشت. بر اساس نتایج آزمایش گلخانه ای هیدروپرایمینگ تا حدودی توانست اثرات مخرب تنش خشکی را کاهش دهد بطوریکه هیدروپرایمینگ 24 ساعت در رقم MCC 510 توانست درصد سبز شدن را به 100 درصد برساند. شاخص بنیه طولی گیاهچه در دو رقم نخود تا تنش خشکی 50 درصد ظرفیت زراعی متفاوت بودند ولی پس از آن با افزایش تنش خشکی این صفت در هر دو رقم کاهش یافت. در رابطه با شاخص بنیه وزنی گیاهچه نیز افزایش تنش خشکی در هر دو رقم سبب کاهش معنی دار آن در تمامی سطوح هیدروپرایمینگ شد. | ||

| Effect of hydropriming on germination and growth indices in chickpea (Cicer arietinum L.) cultivars under drought stress in laboratory and glasshouse condition | ||
| چکیده [English] | ||
| In order to evaluate the effect of hydropriming on germination and seedling growth of Chickpea cultivars under drought stress this study was conducted in two separate experiments. In the first experiment the effect of hydropriming on the germination of two chickpea cultivars ILC6266 and MCC510 were studied in physiology laboratory. The second experiment was conducted in research greenhouse in same location. Drought treatments were 70, 50 and 30 percent of field capacity. Analysis of variance showed that increasing the duration of soaking in water to 24 hours, the germination percentage and germination rate increased 8 % and 25 % respectively. Seed priming increased radicle and plumule length of both cultivars, but the MCC 510 has a length of radicle and plumule was higher than the ILC 6266. Also with increasing duration of hydro to 24 hours seed length vigor of MCC 510 and ILC 6266 was increased 41% and 52% compared control condition. Based on the results of glasshouse drought severely reduced germination percentage of both cultivars, although somewhat priming could reduce the damaging effects of water stress as a priming for 24 hours could caused 100% percentage of emergence in the MCC 510. Both cultivars under drought stress in seedling death was caused without priming but The hydropriming for 24 hours could increase 74 percent dry matter chickpea cultivars compared control condition. In conjunction with plant weight vigor also increase drought stress caused a significant reduction of both cultivars in all levels of hydropriming. | ||
