A water culture experiment was conducted using two cultivars of tomato namely: Castle Rock (salt sensitive) and Super Strain -B (salt resistant), to study their response to NaCl stress. NaCl was supplied in three levels (0.0-10mmol-100mmol). Shoot, root dry weights, nutrients concentration, nutrient ratios, lipid peroxidation, POD and SOD activities were used as biochemical assays for assessing salt tolerance. The results of this study indicate that compared with Castle Rock the Na/K ratio as well as the lipid peroxidation in respect of MAD-content were much lower in Super Strain -B. The activities of POD and SOD were higher in Super Strain -BB at 100 mmol NaCl. So the decreases in Na/K ratio and (MAD content), moreover, the increases in POD, SOD levels may be used for screening cultivar tolerance to NaCl stress. In addition, Super Strain -B was found to be more tolerant to NaCl salt stress compared to Castle Rock cultivar.
