The aim of the study to explain the role of ascorbic acid (AsA) for alleviates the effect of salinity stress on special cultivar (cv. Bonus F1) of tomato plant. The tomato seeds (cv. Bonus F1) soaked in AsA (0.75 mM) before germinated for 12 hours in the dark. The seeds planted in trays of cork contain 218 eyes for 14 days, seedlings plant transplanted to plastic containers containing a mixture of sand/peat-moss (1:2). Each pot contained 7 seedling plants were irrigated using different concentrations (1,500 - 3,000 - 4,500 & 6,000 ppm) NaCl. The data explained that the catalase enzyme activity increased significantly in the present of AsA more than in the absent of AsA under NaCl salinity stress compared with control. Also, the results indicated that the contents of macro and micro nutrient mineral elements (N, P, K, Ca, Mg, Mn, Fe, Cu, Z, B, Na and Cl) increased significantly more under salinity stress in the presence more in the absence of ascorbic acid compared with the control. The data provide strong support to the hypothesis that exogenous of ascorbic acid (AsA) reduces the harmful effects of salinity and increases resistance to salinity in tomato plant.
