摘　　要：本文对大豆在盐胁迫条件下农艺性状及籽粒化学品质进行了研究。盐胁迫条件下，植株高度下降，主茎节数和分枝数减少，百粒重降低，单株荚数、粒数和粒重下降，从而导致产量降低。对处敏感品种比耐盐品种受盐胁迫的影响更大。一般说来，盐使大豆籽粒蛋白质含量显著下降，脂肪含量显著提高，脂肪酸中组成的亚油酸和亚麻酸含量显著增加，油酸含量显著降低。但在盐碱地上高浓度盐胁迫下蛋白质含量增加，脂肪含量下降，不饱和脂肪酸组成上则没有显著差异。Agricultural characters and chemical qualities of seed in soybeans were studied under salt stress conditions.Plant height,node number of main stem,branch numder,100 seed weight,pod numbed per plant,seed number per plant,seed weight per plant and yield were decreased under salt stress condition.Susceptible varieties to salt stress were more effected than tolerant ones.In general,protein content in seed decreased and fat content in seed increased significantly under salt stress.Linoleic acid and lindenic acid increased and oleic acid decreased significantly.But protein content increased and fat content decreased under stress of high salt concentration Unsatunated fatty acid composition were not different significantly at the same condition.
