| یکی از مسائل مهم در مناطق خشک و نیمه خشک کمبود آب است، بنابراین انتخاب گونه‌های گیاهی دارویی مقاوم به خشکی بویژه در مرحله جوانه‌زنی بذر و سبز شدن اهمیت زیادی دارد. در این تحقیق ابتدن تیمار سرمادهی مرطوب جهت شکست خواب بذور وشاء (Dorema ammoniacum) بررسی شد. سپس بذور تیمار شده در محیط کشت جوانه‌زنی همراه با تنش خشکی به مدت 20 روز در دمای 15 و 20 درجه سانتی‌گراد قرار داده شد. آزمایش تنش خشکی، در قالب آزمایش فاکتوریل و به صورت طرح کاملا تصادفی در 5 سطح، شامل ایجاد تنش اسمزی بر اساس پتانسیل‌های اسمزی محلول حاوی پلی‌اتیلن گلایکول 4- ، 8- ، 12- و 16- بار و بدون تنش یا شاهد استفاده شد. نتایج نشان داد با افزایش شدت تنش اسمزی به طور معنی‌داری (p <0/01) از سرعت و درصد جوانه‌زنی، طول ریشه‌چه و ساقه‌چه کاسته می‌شود. متعادل‌ترین محدوده تنش اسمزی جهت بهیود جوانه‌زنی، پس از شرایط عدم تنش، حداکثر 12- بار تنش در پتانسیل اسمزی بود. به نظر می‌رسد طول ساقه‌چه در بین سایر صفات مورد بررسی از حساسیت بالاتری نسبت به تنش اسمزی برخوردار است. در ضمن مناسب‌ترین دما برای جوانه‌زنی وشاء تحت تنش تیمار خشکی دمای 20 درجه سانتی‌گراد بود. | ||

| Water deficiency is one of the important problems in arid and semi-arid regions. Thus, in germination and growing stages selection of resistant medicinal plant species is very important. In this investigation in order to seed dormancy breakage of Dorema ammoniacum seeds, wet cooling treatment was assessed first. After selection of the best cooling treatment (5 °C), treated seeds were placed in germinating medium with drought stress; at a period of 20 days at 15 and 20 °C. Drought stress trial was conducted at 5 levels as factorial layout based on a completely randomized design including control, -4, -8, -12, and -16 bar treatments. PEG was used to make drought stress. Results showed germination rate and percentage, radicle length, and stem length were significantly (p < 0/01) decreased by increasing drought stress. The best range for germination in conditions of without stress was to -12 bar water potential. It appears that stem length was more vulnerable than other characters. In addition, 20 °C was the most appropriate temperature for germination under drought treatment. | ||
