| چکیده | ||
| استقرار اولیه گونههای گیاهی مرتعی به خصوص در مناطق خشک و نیمه خشک مسئلهای قابل توجه جهت اصلاح و توسعه مراتع و افزایش عملکرد آنها میباشد. به منظور بررسی اثرات کاربرد پرایمینگ بذر بر تغییرات عملکرد گونه مرتعی Astragalus brachyodontus، طرح حاضر در گلخانه و در قالب طرح فاکتوریل انجام گرفت. سه تیمار هیدروپرایمینگ (آب مقطر)، اسموپرایمینگ (پلی اتیلن گلایکول در دو سطح 4/0- و 8/0- مگاپاسکال) و هورمون پرایمینگ (جیبرلیک اسید) به عنوان فاکتور اول و سه سطح تنش کمآبیاری 100% ظرفیت مزرعه، 75% ظرفیت مزرعه و 50% ظرفیت مزرعه به عنوان فاکتور دوم بر روی سه جمعیت (زنجان، قم و خلخال)، در سه تکرار در نظر گرفته شد. بررسی نتایج نشان داد پرایمینگ بذر، تنش کمآبیاری، جمعیتها و اثرات متقابل آنها، تاثیر معنیداری در سطح احتمال 1% بر تمام صفات مورد بررسی داشت. کاهش میزان آب خاک، موجب کاهش معنیدار درصد جوانه زنی، طول و وزن ساقه شد اما طول ریشه افزایش یافته و وزن ریشه ابتدا افزایش و سپس کاهش شدیدی نشان داد. بیشترین میزان عملکرد صفات ارتفاع (0267/11 سانتیمتر)، طول ریشه (6467/30 سانتیمتر)، وزن ساقه (1700/1 گرم) و وزن ریشه (3664/1 گرم)، مربوط به جمعیت زنجان با آبیاری نرمال بود. تیمار اسموپرایمینگ 4/0- مگاپاسکال بیشترین مقادیر را در صفات طول ریشه (1556/33 سانتیمتر)، وزن ساقه (2144/1 گرم) و وزن ریشه (4800/1 گرم) داشت. به طور کلی، بر‌اساس نتایج تحقیق حاضر، اسموپرایمینگ 4/0- مگاپاسکال و هورمون پرایمینگ با جیبرلیک اسید در شرایط تنش شدید کمآبیاری، به عنوان تیمارهای بهبود دهنده عملکرد گونه Astragalus brachyodontus در محیط گلخانه معرفی شد. این مسئله می‌تواند در بهبود استقرار و عملکرد این گونه علوفه ای با ارزش بومی در برنامه های اصلاح و توسعه مراتع برای کمک به استقرار اولیه آن ها در شرایط کمآبیاری مورد توجه واقع شود. | ||

| چکیده [English] | ||
| Early establishment of rangeland plant species, especially in arid and semi-arid regions, is a considerable issue to increase their yield. In order to investigate the effects of seed priming on changes in yield of the Astragalus brachyodontus pasture species, the present study was carried out in the greenhouse with factorial design. Three treatments of hydro-priming (distilled water), osmopriming (Polyethylene Glycol with two levels of -0.4 and -0.8 MPa) and hormone priming (gibberellic acid) as the first factor, and three levels of deficit irrigation stress (100% field capacity, 75% field capacity and 50% field capacity) were considered as the second factor and 3 populations (Zanjan, Qom and Khalkhal) as the Third factor with 3 replications. The results showed that seed priming, deficit irrigation stress, populations and their interactions had a significant effect at the 1% probability level on all investigated traits. The soil water reduction caused a significant decrease in seedling germination percentage, stem length and weight, but the root length increased and the root weight first increased and then decreased intensively. The maximum yield of height (11.0267 cm), root length (30.6467 cm), stem weight (1.1700 g) and root weight (1.3664 g) was related to Zanjan population in normal irrigation. The treatment of -0.4 MPa osmopriming had the highest values in root length (33.1556 cm), stem weight (1.2144 g) and root weight (1.4800 g). Generally, according to the present research, -0.4 MPa osmo-priming and hormone priming with gibberellic acid were introduced as treatments to improve the Astragalus brachyodontus species performance in the greenhouse under the severe deficit irrigation stress condition. This results can be considered to improving the establishment and performance of this native valuable forage, in breeding programs and rangeland development, to improve its initial establishment in deficit irrigation conditions. | ||
