| 摘 要： | 以2个不同耐旱性大豆品种为材料,研究了干旱胁迫对大豆花荚期叶片保护酶活性和膜脂过氧化作用的影响。结果表明:随着干旱胁迫的增强,质膜透性和MDA含量逐渐增加,SOD、POD和CAT活性表现为先升后降趋势;耐旱性品种比不耐旱性品种具有较低的质膜透性和MDA含量,同时具有较高的SOD、CAT和POD活性;重度干旱胁迫下POD活性高于SOD、CAT活性。

| Abstract: | The effects of drought- stress on the protective enzyme activity and membrane lipid peroxidation in leaf of soybean flowering-poding period and their relationship with the tolerance to drought were studied with two different drought- tolerant cultivars. The result showed that with the strength of drought- stress, permeability of plasmas membrane and contents of MDA increased gradually, and activities of SOD, POD and CAT rose at first and lowered later. Much lower rate of permeability of plasma membrane and malondialdephyde (MAD) content were appeared in drought- tolerant cultivars than those in drought- sensitive cultivars under drought- stress. And the drought- tolerant ones had higher SOD, CAT and POD activities. In severe drought conditions, the activity of POD was higher than those of SOD and of CAT. |
