Abstract :

جهت بهبود ماندگاری پس از برداشت گل بریده آلسترومریا (Alstroemeria hybrida) آزمایشی فاکتوریل بر پایه طرح کاملا تصادفی با 2 فاکتور: شکاف ته ساقه (5 سانتی‌متر و بدون شکاف) و اتانول در 5 سطح (0، 1، 2، 4، 6 درصد) با 10 تیمار، 3 تکرار و 30 پلات انجام شد. در این آزمایش صفاتی از قبیل عمر گلجایی، جذب آب، وزن تر، درصد ماده خشک، اتیلن، آنتوسیانین گلبرگ، نشت یونی و لیپید پراکسیداسیون (MDA) مورد ارزیابی قرار گرفت. تجزیه واریانس داده‌ها نشان داد که اختلاف معنی‌داری بین تیمارهای مختلف در صفات عمر گلجایی، جذب آب، درصد ماده خشک و نشت الکترولیت در سطح احتمال 5 درصد و برای سایر صفات در سطح احتمال 1 درصد وجود داشت. نتایج نشان داد که تیمارهای مختلف موجب بهبود عمر گلجایی نسبت به شاهد شدند و حداکثر عمر گلجایی با 77/19 روز در تیمار اتانول 1 درصد + شکاف 5 سانتی‌متری ته ساقه به‌دست آمد که نسبت به شاهد (09/11 روز) موجب افزایش عمر گلجایی شد.
