摘　　要：以4种不同小麦品种为材料,通过发芽试验,系统比较了浓度0.15%盐溶液对不同小麦种子发芽率、发芽速度、发芽指数、活力指数、苗高以及a-淀粉酶和游离脯氨酸含量的影响。研究结果表明:在盐胁迫下,4个小麦品种发芽率、发芽指数、活力指数以及a-淀粉酶均受到不同程度的抑制,游离脯氨酸含量明显增加。品种耐盐性由强到弱依次为百农3236、矮早781、温麦8号、百矮58。Four different wheat varieties were used for germination experiment. Effect of 0.15 % salt stress on seed germination percentage, germination rapidity, germination index, vigor index, bud length, content of α-amylase and free proline were studied. The results showed that under salt stress, seed germination percentage, germination index, vigor index and α-amylase content of different wheat varieties were suppressed in different degrees. Free praline content increased significantly, Salt resistance from strong to weak was Bainong 3236, Aizan 781 and Wenmai No.8, in which Bainong 3236 was the best.
