Four legume plants showed better growth by the external nitrogen supply rather than the symbiotic nitrogen fixation only under salt additions. In case of Glycine max and Phaseolus angularis, total nitrogen contents decreased by high salinity level but their amino acid levels significantly increased with the increase of salt treatments and indicated high soluble-/insoluble-N ratios. Cassia tora and Albizzia julibrissin contained less amino acids than G. max and P. angularis but total N (esp. insoluble N fraction) increased with higher salt levels. Asparagine occurred as a main amino acid especially in G. max and P. angularis and can be seen as potential N-storage form in these plants. It might be play an important role for the osmoregulation mechanism under the saline condition. Meanwhile, to investigate what kinds of nitrogen sources are effective for overcoming salt stress on soybean plants, various N forms and concentrations (NH©þNO©ý-N, NO©ý-N, NH©þNO©ý-N; 2.5 and 5 mM) were additionally supplied to the salt gradient medium. Soybean plants treated with NH©þNO©ý-N showed the best growth up to 40 mM NaCl and NO©ý- fed plants indicated good growth even at 80 mM NaCl treatments. Contrary to NH©þNO©ý- and NO©ý- fed plants, NH©þ/sup +/- fed plants showed remarkable growth reduction and died by 40 and 80 mM NaCl treatments after the first harvest (15th day). Consequently, these results suggest that salt excluding and resistant capacities of soybean plants under NaCl treatments are increased in order of NH©þ - N, control, NO©ý- N and NH©þNO©ý- N depending on N concentration except NH©þ- N treatments.
