摘要:用不同电场强度处理雀麦种子5 min,在室温条件下,培养9 d后,测定其丙二醛(MDA)的含量以及超氧化物歧化酶(SOD) 和过氧化物酶(POD)的活性.结果表明:在正常的水份和室温条件下,不同场强处理后的冰草种子,幼苗中的MDA含量、SOD和POD的活性发生不同变化,变化幅度分别为-5.8%~38.9%,-43.4%~92.6%和-23.2%~88.2%.

Abstract: Gaertn seeds were treated with different electric field strength for five minutes.After being cultured for nine days in room temperature,the contents of MDA and the activity of POD and SOD were tested.The results show that,in condition of normal moisture and room temperature,different electric field strength have different effects on POD,SOD and MDA.The changed degree of the MDA(malon-di-aldehyde) is from -5.8% to 38.9%,of the SOD(superoxide dismutase) from -43.4% to 92.6% and of the POD(peroxidase) from -23.2% to 88.2%.

Key words: electric field, gaertn, enzyme activity
