چکیده

به‌منظور بررسی تاثیر روش مصرف سایکوسل بر برخی صفات مورفولوژیکی و فیزیولوژیکی گل آزالیا رقم ژاپونیکا قرمز، دو آزمایش مجزا هر کدام به‌صورت طرح کاملاً تصادفی با پنج تیمار و سه تکرار انجام شد. به این منظور، سایکوسل با دو روش محلول­پاشی بوته‌ها با غلظت­های صفر (شاهد)، 1000، 2000، 3000 و 4000 میلی­گرم در لیتر و از طریق ریشه با غلظت­های صفر (شاهد)، 750، 1500، 2000 و 2500 میلی­گرم در لیتر استفاده شد. نتایج نشان داد که با روش محلول‌پاشی برگی، در غلظت 4000 میلی‌گرم در لیتر سایکوسل بیشترین تعداد گل (33/21 عدد)، تعداد شاخه (4/13 عدد)، کلروفیل کل (34 میکرو‌گرم بر گرم وزن تر) و آنتوسیانین (29/16 میلی‌گرم بر گرم وزن تر) مشاهده شد. در روش تیمار از طریق ریشه نیز کاربرد 2500 میلی‌گرم در لیتر سایکوسل، موجب افزایش تعداد گل (66/16 عدد)، تعداد شاخه (7/8 عدد)، کلروفیل کل (49 میکرو‌گرم بر گرم وزن تر) و آنتوسیانین (12/16 میلی‌گرم بر گرم وزن تر) گردید. حداکثر زمان باز شدن گل‌های آزالیا در تیمار محلول‌پاشی با مصرف 1000 میلی‌گرم در لیتر سایکوسل طی 183 روز به‌دست آمد، در حالی که در روش تیمار از طریق ریشه با مصرف 2500 میلی‌گرم در لیتر سایکوسل طی 210 روز اتفاق افتاد. به طور کلی در روش محلول‌پاشی با غلظت 4000 میلی‌گرم در لیتر سایکوسل در مقایسه با روش تیمار از طریق ریشه گیاه، شاخص مطلوب پاکوتاهی جهت افزایش بازار پسندی گیاه آزالیا مناسبتر بود.

چکیده [English]

In order to investigate the effect of cycocel consumption on some morphological and physiological traits of azalea cultivar Japonica red, two separate experiments as a completely randomized design with five treatments and three replications were conducted. For this purpose, cycocel with two methods of foliar spraying of plants with concentrations of zero (control), 1000, 2000, 3000 and 4000 mg / l and soaking the root area with concentrations of zero (control), 750, 1500, 2000 and 2500 mg / l was used. The results showed that by foliar application, at a concentration of 4000 mg / l cycocel, the highest number of flowers (21.33), number of branches (13.4), total chlorophyll (34 μg/g FW) and anthocyanin (16.29 mg /g FW) was observed. In root soaking method, application of 2500 mg /l of cycocel increases the number of flowers (16.66), number of branches (8.7), total chlorophyll (49 μg/g FW) and anthocyanin (16.12 mg /g FW). The maximum time of flower opening of azalea was achieved in foliar application at 1000 mg /l cycocel in 182 days, while in the root soaking method at 2500 mg / l cycocel occurred in 210 days. Overall, in the foliar application method with a concentration of 4000 mg/l cycocel in comparison to the root soaking method, the optimal dwarfism index is more suitable to increase the marketability of azalea.
