| 摘 要： | 经蚕豆盆栽试验,观察到水分胁迫下,蚕豆膜脂过氧化作用明显加强,O_2产生速率,MDA积累增多,质膜相对透性增大,其原因是水分胁迫下,SOD、POD、CAT等膜保护酶活性降低,活性氧代谢平衡失调所致。

| Abstract: | By the pot culture method of vicia faba L. It was observed that peroxidation of membranes of Vicia faba L.energized significantly under water stress, and O_2, and MDA increased, which caused the membrane permeability injury.Its cause was that the activities of ceifensive enzymes SOD, POD, CAT etc. decreased under water stress, which caused a-vidity peroxide of metabolism unbalance |
