| گل رز از مهمترین گل‌های بریده در جهان است. پژوهشی به منظور بررسی اثرات بنزیل‌آدنین و 1- متیل سیکلو-پروپن جهت کاهش فعالیتهای تسریع کننده فرایند پیری توسط اتیلن و افزایش ماندگاری گل رز رقم رویال باکارا در سال 2017در منطقه پاکدشت استان تهران انجام گردید. این آزمایش به‌صورت فاکتوریل در قالب طرح کاملا بود و فاکتورهای مورد بررسی شامل بنزیل‌آدنین در سه سطح صفر (شاهد)، 75 و 150 پی‌پی‌ام و 1- متیل سیکلوپروپن در سه سطح صفر (شاهد)، یک و دو میکرولیتر بر لیتر بودند. روش نگهداری پس از برداشت گل شاخه بریده به صورت تیمار کوتاه مدت(پالسینگ) بود . نتایج نشان داد که اثر متقابل کاربرد بنزیل‌آدنین و 1-متیل سیکلوپروپن بر محتوای اتیلن، مارکر زیستی مالون دی آلدئید(MDA)، آنزیم سوپراکسید دیسموتاز(SOD)، مارکر زیستی تخریب دی تیروزین، درصد نشت یونی غشاء سلول، میزان پتاسیم وعمر گلدانی گل رز معنی‌دار بود. بیش‌ترین میزان آنتی اکسیدانSOD، عمرگلجایی و میزان پتاسیم از تیمار 150 پی‌پی‌ام بنزیل آدنین با 2 میکرولیتر بر لیتر 1- متیل سیکلوپروپن حاصل شد و این تیمار، کمترین محتوای مارکرهای زیستی تخریب مالوندی‌آلدئید و دی تیروزین، تولید اتیلن و درصد نشت یونی را داشت که بیانگر تاثیر مثبت بنزیل آدنین و 1- متیل سیکلوپروپن بر ماندگاری گل شاخه بریده رز می باشد. نتایج کلی این تحقیق نشان داد که با کاربرد توام یک یا دو میکرو لیتر در لیتر 1- متیل سیکلوپروپن و 150 میلی گرم در لیتر بنزیل آدنین می توان ماندگاری گل شاخه بریده رز را بهبود داد. | ||

| چکیده [English] | ||
| In order to investigate the application effects of different levels of benzyl adenine ( BA) and 1-methylcyclopropene (1-Mcp) on some bio-chemical characteristics and vase life of rose (Rosa hybrid L. cv. Royal Bacara),an experiment was carried out as factorial based on completely randomized design with three replications during 2017. Experimental factors included BA in three levels of 0, 75, and 150 ppm, and 1-Mcp in three concentrations of 0, 1, and 2 (µlit.lit). The results showed that the interaction of BA and 1-Mcp was significant on the biochemical characteristics and the vase life of roses.The highest antioxidant rate SOD, K and vase life in the treatment of 150 ppm BAalong with 2 µlit/lit 1-Mcp was achieved. This treatment was allocated the lowest rate MDA, DT and Ec. This results indicated that BA and 1-Mcp have effect on durability of rose.In general, the result showed that application of 1 or 2 µlit/lit 1-Mcp along with150 ppm AB was improve some physiological and biochemical characteristics and vase life ofrose cut flower. | ||
