| 摘 要： | 采用土培方式,研究了9703,浙春2号,浙春3号等3个不同大豆品种对铝毒抗逆性的影响。结果表明,铝胁迫下,大豆各品种质膜透性增大,丙二醛和脯氨酸含量增加,根瘤数量减少,根系活力下降。从种间差异性来看,3个大豆品种对铝毒的抗逆性不同,按耐铝性大小依次为:浙春2号>9703>浙春3号。

| Abstract: | Using soil culturing, the stress resistance of three varieties ( 9 70 3, Zhechun No.2 and Zhechun No.3) of soybean to aluminum (Al) toxicity was studi ed. The results showed that under aluminum stress, membrane permeability of soyb ean leaves, the contents of proline and malondialdehyde (MDA) of soybean leaves were increased, and numbers of root nodule and activity of root of soybean were decreased. From the differences among genotypes, the stress resistance of three varieties to Al toxicity was different. The stress resistance of three varieties was showed that: Zhechun No.2 > 9703 >Zhechun No.3. |
