摘要:
Results of solution culture experiments on effects of N, P, and K deficiencies on S constituents of leaf blades, total S concentrations, and S uptake by soybean plants are reported. Nitrogen deficiency decreased the concentration of soluble protein S, had little effect on nonsoluble S, and increased concentrations of soluble nonprotein S, sulfate S, reduced non‐protein S, and total S of soybean leaf blades. Soluble protein and S content of soluble protein decreased under N‐deficient conditions. For whole plants, S concentration and S uptake increased while dry weight was unaffected by N deficiency.
