چکیده

به‌منظور بررسی میزان تحمل به یخ‌زدگی گیاه پنیرباد آزمایشی در قالب طرح کاملاً تصادفی با 4 تکرار و نه تیمار دمایی (صفر، 3-، 6-، 9-، 12-، 15-، 18- و 21- درجه سانتی‌گراد و تیمار شاهد ۲5 درجه سانتی‌گراد) انجام شد. صفات مورد مطالعه شامل درصد نشت یونی، پایداری غشای سلولی، محتوای پرولین برگ، کلروفیل فلورسانس، درجه سبزینگی، دمای 50 درصد کشندگی بر اساس درصد بقا (LT50su) و دمای 50 درصد کشندگی بر اساس نشت الکترولیت‌ها (LT50el) بود. نتایج نشان داد اثر تنش یخ‌زدگی بر تمامی صفات مورد مطالعه در سطح احتمال 1 درصد معنی‌دار بود. با افزایش تنش یخ‌زدگی نشت یونی افزایش و پایداری غشای سلولی کاهش نشان دادند. میزان کلروفیل فلورسانس برگ با افزایش تنش کاهش یافت، به طوری که در دماهای پایین تر از 9- درجه سانتی‌گراد به کمترین مقدار خود رسید. درجه سبزینگی تا 6- درجه سانتی‌گراد با شیب شدید و در کمتر از آن با شیب ملایم تر کاهش یافت. بیشترین محتوای پرولین مربوط به تیمار 6- درجه سانتی‌گراد بود که نسبت به تیمار شاهد 53 درصد افزایش یافت. با کاهش دما درصد بقا کاهش یافت، به طوری که در دماهای زیر 9- درجه سانتی‌گراد به کلی گیاهان از بین رفتند. همچنین LT50el  و LT50su  به ترتیب در دمای 153/10- و 958/8- درجه سانتی‌گراد اتفاق افتاد. در نهایت، یافته ها در این تحقیق نشان دادند که گیاه دارویی پنیرباد تنش یخ‌زدگی 6- درجه سانتی‌گراد را به طور قابل قبولی تحمل می‌نماید.

چکیده [English]

In order to investigate freezing tolerance in withania under controlled conditions, a completely randomized design was carried out with four replications and nine temperature treatments (0, -3, -6, -9, -12, -15, -18, -21 °C and control treatment 25°C). Studied traits included electrolyte leakage, cell membrane stability, proline content, chlorophyll fluorescence, chlorophyll degree, 50% lethal temperature based on survival (LT50su) and 50% lethal temperature based on electrolyte leakage (LT50el). Results showed that the effect of freezing stress on all traits was significant at a probability of one percent. Electrolyte leakage showed increased and cell membrane stability decreased. The leaf chlorophyll fluorescence decreased with increasing freezing stress, so that it reached its lowest point at temperatures below -9°C. Chlorophyll content index was also affected by the effect of freezing stress, which decreased at a steep slope of 0 to -6°C and lowered to -6 °C with lower slope. The highest content of proline was related to treatment at -6°C, which increased by 53% compared to control treatment. By decreasing the temperature, the survival rate decreased, so that the plants disappeared at temperatures below -9°C. Also, LT50el and LT50su occurred at temperatures of -10.153 and -8.958°C, respectively. Finally, the findings in this study showed that the medicinal plants withania can be tolerate at -6°C.
