摘　　要：以大豆品种浙春3号和华春18为材料,设置不同铝浓度处理,研究了铝对这2个大豆品种种子萌发的影响。结果表明,低浓度的铝降低了种子质膜透性,提高了种子的发芽率、发芽势和发芽指数,对种子的发芽有一定的促进作用,而高浓度的铝则对萌发有一定的抑制作用。同时,2个大豆品种对铝的敏感度以及耐铝性都不同。The seeds of two different variety soybean （Zhechun 3 and Huachun 18） were soaked for 3 hours with different Al^3＋ concentration and then germinated for 7 days. The results showed that low Al^3＋ concentration could promote the seed germination. However, high Al^3＋ concentration had the opposite effects. The stress resistence and the sensitive of two soybean varieties were different.
