| چکیده | ||
| کما گیاهی دارویی متعلق به خانواده چتریان است که از علوفه خشک آن برای تعلیف دامها استفاده میشود. بهره برداریهای بیرویه از عرصه های طبیعی، این گیاه را در معرض نابودی قرار داده است. بذر کما به دلیل داشتن خواب جوانهزنی اندکی دارد. به منظور شکستن خواب بذر این گیاه آزمایشی با 28 تیمار در قالب طرح کاملاً تصادفی در 4 تکرار در آزمایشگاههای تکنولوژی بذر و تحقیقاتی دانشکده کشاورزی دانشگاه بیرجند اجرا گردید. تیمارها شامل آبشویی به مدت 6 و 12 ساعت، خراش_دهی شیمیایی با اسید سولفوریک 80 درصد به مدت 5 و 10 دقیقه، نیترات پتاسیم 3/0 درصد به مدت 72 ساعت، تیمارهای هورمونی جیبرلیک اسید (250، 500 و 1000 پیپیام) و بنزیل آمینوپورین (1/0 و 25/0 میلیگرم بر لیتر)، سرمادهی مرطوب به مدت 20 ، 35 و 50 روز در دمای 5+ درجه سانتی گراد و تیمارهای توأم سرمادهی و هورمونی بودند. نتایج نشان دادند که اثر تیمارهای مذکور بر درصد، سرعت، میانگین زمان جوانهزنی و بنیه بذر کما معنیدار بود (1%≤ P). سرمادهی مرطوب عاملی ضروری برای شکستن خواب بذر کما بود. تیمارهای هورمونی سبب بهبود خصوصیات جوانه زنی بذرهای این گیاه شدند. تیمار 50 روز سرمادهی مرطوب در دمای 5+ درجه سانتیگراد توأم با 500 پی پی ام جیبرلیک اسید، بهترین تیمار برای شکستن خواب بذر کما بود | ||
