| این آزمایش به منظور بررسی پاسخ جوانهزنی بذر بادرنجبویه (.Melissa officinalis L) نسبت به دما و پتانسیل آب صورت گرفت. دماهای استفاده شده در این آزمایش، 10 سطح دما شامل 5، 10، 15، 20، 23، 25، 27، 30، 32 و 35 درجه سانتیگراد بود. در هر دما تاثیر تنش شوری شامل صفر،0/2-، 0/4-، 0/6- و 0/8- مگاپاسکال سدیم کلرید وتاثیر تنش خشکی شامل صفر،0/2-، 0/4-، 0/6- و 0/8- مگاپاسکال پلی اتیلن گلایکول بر خصوصیات جوانهزنی مورد بررسی قرار گرفت. این آزمایش در آزمایشگاه بذر پردیس کشاورزی و منابع طبیعی دانشگاه تهران در سال 1393 انجام شد. دادهها بصورت فاکتوریل در قالب طرح کاملا تصادفی با چهار تکرار آنالیز شدند. نتایج نشان داد که اثر دما در پتانسیل آب بر شاخصهای جوانهزنی معنیدار بود. صفات مورد مطالعه عبارت بودند از درصد جوانهزنی، سرعت جوانهزنی، طول ریشهچه و ساقهچه و شاخص بنیه. با افزایش شدت کلرور سدیم و پتانسیل اسمزی درصد و سرعت جوانهزنی بذرهای بادرنجبویه به طور خطی کاسته شد و در هر دو آزمایش بیشترین درصد جوانهزنی مربوط به تیمار شاهد (90 درصد) و کمترین درصد جوانهزنی (20 درصد) مربوط به پتانسیل 0/8- مگاپاسکال بود. با کاهش پتانسیل آب و افزایش میزان شوری، شاخص بنیه گیاهچه کاهش پیدا نمود. بذرهای بادرنجبویه در دماهای 5، 10، 15 و 35 درجه سانتیگراد و در هیچ سطح رطوبتی جوانه نزدند. نتایج این پژوهش میتواند برای مطالعات آتی در مورد اکولوژی بذر گیاه بادرنجبویه مفید باشد. | ||

| چکیده [English] | ||
| This study was conducted to evaluate the effects of water potential and temperature on seed germination rate of lemon balm (Mellissa officinalis L.). Temperatures used in this experiment had 10 temperature levels including 5, 10, 15, 20, 23, 25, 27, 30, 32 and 35 ° C. At each temperature the effect of salinity levels (0, -0.2, -0.4, -0.6 and -0.8 MPa of Sodium chloride) and the effect of drough levels (0, -0.2, -0.4, -0.6 and -0.8 MPa of Polyethylene glycol) on germination characteristics was studied. This study was conducted in Seed Laboratory, College of Agriculture and Natural Resources, University of Tehran in Karaj in 2015. Data were analyzed using factorial design in a completely randomized design with four replications. The results showed that the effect of temperature and water potential was significant on germination indices. Traits studied were germination percentage, germination rate, root and shoot length and seedling vigor index. The germination percentage and germination rate of lemon balm decreased linearly by increasing salinity and drought stress. In both experiments, the highest (90%) and lowest (20%) germination percentage was observed in control and the potential of -0.8 MPa, respectively. Seedling vigor index decreased by decreasing water potential and increasing in salinity level. Lemon balm seeds did not germinated in 5, 10, 15 and 35 ° C in any moisture levels. The results can be used for future studies on the seed ecology of lemon balm. | ||
