| چکیده | ||
| به منظور بررسی اثر تنش خشکیو کود نیتروژن بر بنیهبذر حاصل از گیاه مادری لوبیا قرمز، آزمایشی به صورت اسپلیت پلات فاکتوریل در شرایط مزرعه انجام گرفت. تیمارهای تنش خشکی به عنوان عامل اصلی در سه سطح آبیاری نرمال به عنوان بدون تنش (60 میلی متر تبخیر از تشتک تبخیر)، تنش خفیف (90 میلی متر تبخیر از تشتک تبخیر) و تنش شدید (120 میلی متر تبخیر از تشتک تبخیر) بودند. کود نیتروژن در چهار سطح صفر، 50، 100 و 150 کیلوگرم نیتروژن در هکتار و دو ژنوتیپ لوبیا قرمز شامل رقم اختر و لاین D81083نیز به عنوان عامل فرعی به صورت فاکتوریل در نظر گرفته شدند. پس از برداشت بذرها در مرحله رسیدگی کامل، کیفیت بذر با استفاده از آزمونهای جوانهزنی استاندارد و هدایت الکتریکی مورد ارزیابی قرار گرفت. این آزمونها به صورت فاکتوریل در قالب طرح کاملاً تصادفی انجام گرفت. نتایج نشان داد که اعمال تنش خشکی بر روی گیاه مادری سبب کاهش صفاتی نظیر درصد گیاهچههای طبیعی، طول و وزن خشک ریشهچه و ساقهچه، و بنیه گیاهچه حاصل از بذور گیاه مادری گردید. نیتروژن نیز سبب افزایش میزان هدایت الکتریکی بذر، طول ریشهچه، طول ساقهچه و شاخص طولی بنیه گیاهچه گردید. لاین D81083نیز نسبت به رقم اختر در شرایط بدون تنش از نظر صفات جوانهزنیبرتری داشت اما در سطح تنش شدید تفاوت معنیداری بین این ژنوتیپها مشاهده نشد. | ||

| Effects of drought stress and nitrogen fertilizer on seed vigor of red kidney bean | ||
| چکیده [English] | ||
| To study the effects of drought stress and nitrogen fertilizer levels on some seed quality indices of two red kidney bean genotypes, a field experiment was carried out as a split factorial arranged in a randomized complete blocks design with three replications. The main plots were three drought stress levels [irrigation after 60 (without stress), 90 (mild stress) and 120 (severe stress) mm evaporation from open pan class A] and factorial combinations of N fertilizer at four levels (0, 50, 100, and150 kg N ha-1) and two red bean genotypes (Akhtar and D81083) were assigned in sub-plots. The seeds were evaluated by standard germination test and electrical conductivity (EC) test after harvesting at full ripeness. These experiments were carried out as factorial based on a completely randomized design. Results showed that drought stress decreased normal seedling percentage, root length, shoot length, root weight, shoot weight, and seedling vigor index. Also, application of nitrogen fertilizer increased EC value, root length, shoot length and seedling length vigor index. Generally, germination indices of D81083 in non-stress conditions were better than Akhtar but, there was not significant difference between two genotypes in terms of severe drought stress level | ||
