Soybean (Glycine max) cv. Clark tolerated NaCl salinity up to osmotic potential in soil -1800 kPa, cv. Forest to -1500 kPa and cv. Kint to -1200 kPa. The tolerance of cvs. Clark and Forest was found to be related to the accumulation of soluble proteins, amino acids, proline, K and Ca. The sensitivity of cv. Kint was found to be associated with decrease in water, saccharide, protein, K and Ca contents. The leaf osmotic potential decreased in cvs. Clark and Forest while remained unchanged in cv. Kint.

Keywords: amino acids; carotenoids; chlorophylls; Glycine max; mineral contents; NaCl; proline; proteins; saccharides
