چکیده

باباآدم، گیاهی دارویی از خانواده کاسنی، که درنواحی گرم می‌روید. بذرهای این گیاه به‌علت خواب به سختی جوانه می‌زنند. در این تحقیق به‌منظور تعیین مناسب‌ترین روشی شکستن خواب بذر و مطالعه خصوصیات جوانه زنی بذر، آزمایشی در قالب طرح کاملا تصادفی با 4 تکرار و هر تکرار شامل 25 عدد بذر اجرا شد. تیمارهای آزمایشی شامل پیش سرمادهی بذور مرطوب در دمای 4 درجه سانتیگراد برای مدت 1 و 2 هفته، خیساندن بذرها در محلول اسیدجیبرلیک 300 و 500 قسمت در میلیون و در دو دوره زمانی 24 و 48 ساعت، تیمار تلفیقی خیساندن بذر در محلول اسید جیبرلیک با غلظت 500 قسمت در میلیون با دوره زمانی 24 و 48 ساعت به انضمام سرمادهی بذور به مدت 1 و 2 هفته، خیساندن بذرها در اسید سولفوریک 98% با دوره زمانی 10 و 20 دقیقه)، خیساندن بذرها در آب داغ (C°70 با دوره زمانی10 و 15 دقیقه) و خیساندن بذرها در اسید هیومیک ( mg/L54) بودند. نتایج نشان داد که خواب بذر باباآدم از نوع فیزیولوژیک است، زیرا بیش‌ترین درصد جوانه‌زنی بذرها در اثر اعمال تیمار تلفیقی پیش سرمادهی به مدت دو هفته و اسیدجیبرلیک (48 ساعت) به دست آمد. علاوه بر این، تلفیق تیمار سرمادهی مرطوب (14 روز) و اسید جیبرلیک (ppm 500 - 48 ساعت) جوانه‌زنی را تا 78/97 % افزایش داد. تأثیر سایر تیمارهای استفاده شده در این تحقیق اگرچه از نظر آماری بر شکست خواب این بذرها معنی‌دار ارزیابی شد، ولی در مقایسه با تأثیر تیمارهای اسید جیبرلیک و تلفیق سرما و اسید جیبرلیک زیاد نبود.
