- Abstract:
- ?In order to select soybean varieties with stonger drought resistance,four popular planted soybean cultivars were exposed to drought stress at seedling stage in greenhouse,the activity of superoxidase(SOD),peroxidase(POD),catalase(CAT)as well as malondialdehyde(MDA)content were determined.Under drought stress,the activity of SOD,POD and CAT showed increase and then decrease trend,while MDA content increased steadily.The activity of three protective enzymes in decending order was Kangxian 3,Kangxian 12,Hefeng 50,and Kangxian 9,while MDA content showed opposite trend.Results showed the drought resistance of Kangxian 3 was the highest,and Kangxian 9 was the lowest.
