THIS STUDY includes the role of ascorbic acid (ASA) in increasing the resistance of Triticum aestivum L. (wheat) and Trigonella foenum-graecum L. (fenugreek) plants to sodium chloride stress and its effect on improving growth compared to the control treatment. In this experiment, wheat and fenugreek plants were cultured in soil and irrigated with supplemented with sodium chloride salt at different concentrations (0.0,50,100 or150mM/L) and sprayed with ascorbic acid at three concentrations (0.0,100 or 200ppm/L). The highest concentration of sodium chloride (150mM/L) resulted in a significant decrease in plant height 34.8cm , leaf area 4.199cm² and photosynthetic pigments (chlorophyll a, b, total chlorophyll and carotene) contents 1.355, 0.846, 2.458 and 0.728mg/g fresh weight, respectively.
Significant increases in plant height 42.25cm, leaf area 6.058cm² and photosynthetic pigments (chlorophyll a, b, total chlorophyll and carotene) reaching 1.875, 1.569, 3.652 and 1.007mg/g fresh weight, respectively were observed when ascorbic acid was used at the highest concentration (200ppm/L) of the two plants.
