| چکیده | ||
| پژوهش پیشرو بهمنظور ارزیابی تأثیر تنش شوری بر ویژگیهای مورفوفیزیولوژیک نونهالهای پده(Populus euphratica Oliv.)بهصورت گلخانهای اجرا شد. قلمهها از شاخههای یکساله درختان پده موجود در مراتع بیابانی معصومیه قم جمعآوری شدند و در گلدانهای حاوی مخلوط یکنواختی از شن، ماسه و خاک زراعی کاشته شدند. سپس تنش شوری با استفاده از غلظتهای مختلف کلریدسدیم در چهار سطح 50، 100، 200 و 400 میلیمولار همراه با شاهد دو بار در هفته به مدت دو ماه همراه با آب آبیاری، اعمال شد. نتایج نشان داد که تنش شوری 400 میلیمولار نمک کلریدسدیم موجب خشکیدگی کامل نونهالهای پده شد. در تنش شوری 50 میلیمولار کلریدسدیم، زندهمانی، شادابی، ارتفاع، قطر، وزن خشک برگ، ساقه و ریشه نونهالها اختلاف معنیداری را با تیمار شاهد نشان نداد. صفات مورد ارزیابی در تنشهای شوری بین 50 تا 400 میلیمولار اختلاف معنیداری را با تیمار شاهد نشان داد. همچنین میزان تجمع یونها از جمله کلر، منیزیم، کلسیم، پتاسیم و فسفر در برگ و ریشه اختلاف معنیداری را با نونهالهای شاهد نشان دادند. بهطور کلی نتایج نشاندهنده شورپسندی متوسط پده بود و میتوان این گونه را برای عملیات احیای اراضی شور با سطح ایستابی آب زیاد توصیه کرد. | ||

| چکیده [English] | ||
| This study was conducted in order to Morpho-physiological assessment of salt stress on Euphrates poplar (Populus euphratica Oliv.) seedlings in the greenhouse. Annual stems of Euphrates poplar were collected from Masoumieh desert rangelands (Qom) and were planted in pots containing homogenous mixture of sand, gravel and farm soil. Salinity stress was applied using different levels of NaCl in four levels of 50, 100, 200 and 400 mM and control, with two times a week and for two months with irrigation water. The results showed that salinity stress of 400 mM NaCl causes full dehydration of Euphrates poplar seedlings and this amount of salt tolerance was out of plant tolerance. Also salinity of 50 mM NaCl on the viability and survival traits and characteristics, including growth and vitality, height, diameter, biomass of leaves, stems and roots showed no significant difference with control treatments. Higher salinity levels in some of the characteristics and attributes of viability, vitality and the height and diameter of seedlings in different treatments showed significant difference. Also the amount of accumulation of some elements such as chloride, magnesium, calcium, sodium, potassium and phosphorus, had significant differences (p < 0.01 and p < 0.05) with control treatment. Overall, our results represent that Populus euphratica is a moderate halophyte which could be suggested to reclamation of saline lands with high water table. | ||
