| Abstract:
In this experiment the effects of NaCl addition at 0 (control), 25, 50 and 75 mM concentrations to nutrient solution which containing low and normal levels of calcium, and foliar CaCl2 applications on the dry matter and calcium and oxalic acid contents in tomato plant growing in nutrient solution were examined. Dry matter amount, calcium and oxalic acid contents of tomato plant were decreased by the increasing applications of NaCl to nutrient solutions. Normal calcium content in nutrient solution and foliar calcium chloride applications increased leaf calcium content and decreased oxalic acid content. Physiologically active oxalic acid amount was decreased by salinity. No physiologically active oxalic acid amount was determined in foliar calcium chloride spray application. | |
