Abstract :

یخ زدگی، لایه­ای یا رسوباتی از یخ می­باشد که در شرایط سرما معمولا شب، شکل می­گیرد. اگر دما به اندازه­ای پایین بیاید که سلول­های گیا ه یخ بزنند، گیاهان غیر چوبی می­میرند. بنابراین آزمایش تحقیقاتی طرح گردید تا اثرات محلول­های ضد سرما بر روی رشد، کیفیت گلدهی و پارامترهای بیوشیمیایی در گیاهان زینتی بررسی گردد. محلول ضد سرما در غلظت­های مختلف، (شاهد) T0: 0، T1: 250، T2: 500، T3: 1000، T4: 1500 و T5: 2500 میلی­گرم در لیتر تهیه و بر روی اندام­های گل اختر (Canna Indica)، اطلسی (Petunia Axillaris) و کاغذی (Bougainvillea Glabra) محلول پاشی گردید. نتایج نشان داد که تعداد گل­ها و دوره گلدهی در گیاهان تیمار شده بیشتر از شاد بود. بیشتر تعداد گل و طول دوره گلدهی متعلق به تیمار T5، به­ترتیب 22/81 درصد و 86/13 روز بود.با افزایش غلظت محلول ضد سرما، درصد گیاهان آسیب دیده کاهش یافت. کمترین میزان در تیمار T5 (77/69 درصد) مشاهد شد. با افزایش غلظت محلول ضد یخ، مقدار کلروفیل افزایش یافت. بیشترین مقدار کلروفیل در تیمار T5 (80/50 میلی­گرم در هر گرم) مشاهده شد. با مقایسه اثرات تیمارهای مختلف مشاهده شد که شاهد دارای بالاترین میزان پرولین (56/0 میکرومول در هر گرم) و نشت یونی (9 میلی­زیمنس در گرم در سانتی­متر) بود و با افزایش غلظت محلول ضد یخ، کاهش یافتند. کمترین میزان پرولین (08/0 میکرومول در گرم) و نشت یونی (26/2 میلی­زیمنس در گرم در سانتی­متر) متعلق به تیمار T5 بود. تفاوت تیمارهای مختلف در سطح 1/0 درصد معنی­دار بود.
