摘要
为了提高高粱的质量和产量,分析了高粱抗、感丝黑穗病群体不同时期的SOD、POD、CAT活性以及MDA的含量。结果表明:SOD、POD和CAT的活性为抗病群体高于感病群体;SOD活性在抽穗期最高,POD、CAT活性分别在抽穗期和拔节期表现活性最高;MDA含量在苗期最低。
To improve the quality and yield of sorghum,the change of the activity of SOD,POD,CAT and the content of MDA in four growth periods of sorghum head smut resistance and susceptibility were studied.The results showed that SOD,POD and CAT of head smut resistance were higher than head smut susceptibility in four growth periods;the activity of SOD was the highest in heading stage;the activity of POD and CAT in heading and jointing stage were high than seedling and mature stage;the content of MDA was the lowest in seedling stage.
