Abstract :
بهمنظور بهبود کیفیت پس از برداشت و پتانسیل صادرات گل بریده رُز (Rosa hybrida L.) ارقام ’هپی آور‘ و ’بوردو‘ اثر 1-MCP بهعنوان یک بازدارنده اتیلن تحت مطالعه قرار گرفت. غلظتهای 1-MCP عبارت بودند از: 3/0، 4/0، 5/0 و 6/0 گرم در متر مکعب که برای مدت 18 ساعت در دمای 8 درجه سانتیگراد مشابه شرایط حمل و نقل گلها مورد آزمایش قرار گرفتند. تیمار 1-MCPدر مقایسه با شاهد، بهصورت معنیداری عمر گلجایی را افزایش و کاهش وزن را در هر 2 رقم به حداقل رساند، البته پاسخ رقم ’هپی آور‘ نسبت به رقم ’بوردو‘ بهتر و بیشتر بود. تیمار 1-MCP مقدار نسبی آب (RWC) را نیز در گلها بهبود بخشید. 1-MCP به صورت معنیداری تخریب کلروفیل و کربوهیدراتها را در طول عمر گلجایی در هر 2 رقم به تاخیر انداخت. تولید اتیلن به صورت معنیداری توسط 1-MCP کاهش یافت. شاخص ثبات غشا (MSI) در پاسخ به 1-MCP حفظ شد و MDA کاهش یافت. بهترین تیمارها از این نظر بهترتیب غلظتهای 4/0 و 5/0 برای ارقام ’هپی آور‘ و ’بوردو‘ بودند. تیمار 1-MCP برای ممانعت از اثرات منفی اتیلن روی این دو رقم رُز توصیه میشود.
