Abstract
Seeds of Eruca sativa Mill were soaked in distilled water, NaCl or NaCl with uric acid or arginine or in one of the amino acids. Treatment of seeds of Eruca sativa with arginine and uric acid under saline conditions increased the percent of seed germination from 60% to 80%. Incorporation of these amino acids in the nutrient medium also significantly enhanced the dry weights as well as the contents of chlorophyll and ascorbic acid in the seedlings. Levels of both total amino acids and proline were higher in salinized than in non-salinized plants. The results strongly suggest that incorporation of exogenous amino acids in seeds and seedlings of E.sativa helps to alleviate salt stress in the species.
الملخص
تم نقع بذور الجيرجير في الماء المقطر أو كلوريد الصوديوم أو محلول كلوريد الصوديوم مع حمض يوريك أو حمض أرجنين أو في أحد الحمضين الأمنيين. إن معاملة بذور الجيرجير تحت الظروف الملحية أدت إلى ارتفاع في النسبة المئوية للإنبات من 60% إلى 80%. كما أن استخدام هذه الأحماض في الوسط أدى إلى زيادة واضحة في كل من الأوزان الجافة ومحتويات كل من الكلورفيل وحمض اسكوربيك في البادرات. أن مستويات الأحماض الأمينية الكلية وحمض برولين كانت مرتفعة في النباتات المعاملة بالملح عن غير المعاملة. توضح النتائج أن معاملة بذور الجيرجير بحمض ارجنين أو حمض يوريك تقلل من أثر الإجهاد الملحي.
