به منظور بررسی اثر محلول پاشی قبل از برداشت بنزیل آدنین (BA) در بهبود کیفیت و به تاخیر انداختن پیری گل­ها و برگ­های سوسن هیبرید اورینتال رقم بلادونا پژوهشی به صورت فاکتوریل اسپیلت پلات و 5 سطح (0، 25، 50، 75، 100 پی‌پی‌ام) بنزیل آدنین و با سه تکرار و در دو مرحله محلول پاشی، مرحله اول (آغاز غنچه­دهی) و مر حله دوم (قبل از رنگ­گیری غنچه) و اندازه­گیری صفات در دو روز هفتم و دوازدهم پس از برداشت انجام شد. گل­ها در دو مرحله، آغاز غنچه­دهی و قبل از رنگ­گیری گل­ها در مرحله غنچه محلول پاشی شد­ند. از آب مقطر به عنوان تیمار شاهد استفاده شد. صفاتی مانند ماندگاری گل­ها، میزان پراکسیده شدن لیپیدها در روزهای هفتم و دوازدهم پس از برداشت در گلبرگ­ها و برگ­ها و میزان کاروتنوئیدها در روزهای هفتم و دوازدهم پس از برداشت در گلبرگ­ها اندازه گیری شدند. نتایج نشان داد که محلول پاشی با 100 پی­­­­­­­­­­­­­­­­­­­­­پی­ام BA در مرحله قبل از رنگ­گیری غنچه­های گل بیشترین تاخیر را در پیری گل و برگ در مقایسه با تیمار شاهد داشته است. میزان پراکسیده شدن لیپیدها در برگ و گلبرگ در تیمار 100پی­پی­ام BA به طور معنی­داری نسبت به تیمار شاهد کمتر بود، در مقابل کاروتنوئیدها در گلبرگ در تیمار 100پی­پی­ام BA بیشترین و در شاهد کمترین میزان بود. نتایج این پژوهش نشان داد که بنزیل­آدنین با حفظ پایداری باعث بهبود کیفیت و افزایش ماندگاری گل سوسن می­شود.

چکیده [English]

In order to evaluate the effect of pre-harvest spray with Benzyladenin (BA) on improving flower quality and delaying flower and leaf senescence in Lilium oriental, a study was carried out as a spilt plot factorial experiment where 5 levels of Benzyladenin (0, 25, 50, 75, and 100 ppm) with three replications and two stages of spraying (budding start and before dyeing buds). Assaying the traits were done in seventh and twelfth two-days after harvest. The flowers were sprayed at two stages, budding and before flowering in the bud stage. Distilled water was used as control. Characteristics such as flower shelf life and lipid peroxidation in petals and leaves on seventh and twelfth days after harvest and carotenoids contents of petals on seventh and twelfth days after harvest were measured. Results showed that spraying with 100 ppm BA at the beginning of flower pigmentation was more effective in delaying senescence in flowers and leaves as compared to the control. Lipid peroxidation in leaves and flowers treated with 100 ppm BA application was significantly lower than the control. In contrast, carotenoid content of flowers sprayed with 100 ppm BA was higher and the lowest values were found in the control. In total, it was found that BA maintains stability by improving the quality and prolonging the flowers’ survival.
