Effects of Calcium and Nitrogen on the Growth and Antioxidative Enzyme Activity in Soybean (Glycine max) under Saline Condition

Growth of G. max treated with NO₃--N was decreased by high NaCl treatments, but NH₄NO₃-fed plants showed good growth with enhanced activity of antioxidative enzymes (SOD and APX). Especially, activity of APX was higher in 5 mM NH₄NO₃-fed plants than other types of N-supplied plants throughout the st...

Summary:Growth of G. max treated with NO₃--N was decreased by high NaCl treatments, but NH₄NO₃-fed plants showed good growth with enhanced activity of antioxidative enzymes (SOD and APX). Especially, activity of APX was higher in 5 mM NH₄NO₃-fed plants than other types of N-supplied plants throughout the stress period. Higher SOD activity under salt stress was accompanied by increase in APX activity in 5 mM NH₄NO₃-fed plants. Similarly, application of calcium confirmed somewhat positive effects on growth.
