摘要:
通过对盐胁迫下栽培大豆黑农40的根、茎、叶等不同器官中主要的抗氧化酶活性的测定与分析，探讨了大豆耐盐性的机理。结果表明，黑农40叶片中的SOD、POD和APX活性水平明显高于根部和茎部。叶片中的POD和APX在高盐胁迫下的应答反应都比在低盐时快速。盐胁迫时间的延长引起根、茎、叶中的SOD和POD活性发生明显的下降，在高盐胁迫下这种下降比在低盐时更为急剧。
Abstract:
Salt stress produces secondary oxidant stress on plants.Antioxidative enzymes play important role in removing activated oxygen species.The effects of salt stress on activity of antioxidative enzymes in root,stem and leaves of Glycine max(the salt tolerant Heinong 40) were determined and analyzed to discuss the salt tolerant mechanism of soybean.The results indicated that SOD,POD and APX activity were higher in leaves of Heinong 40 than those in stems and roots-POD and APX in leaves respond more rapidly to high salt stress than to low salt stress.With the increase of salt stress time,SOD and POD activity decreased obviously in leaves,stems and roots,and more dramatically under high salt stress than under high salt stress
