Effects of exogenous arginine and uric acid on eruca sativa mill grown under saline conditions

الملخص EN

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 nonsalinized 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.
