摘    要:选取6个大白菜自交系,对其短期高温处理前后的SOD活性、丙二醛含量、可溶性蛋白含量和叶绿素含量进行了测定。结果表明:短期高温处理前后SOD活性以及叶绿素a和b含量的变化与大白菜自交系的耐热性无关;可溶性蛋白含量和丙二醛含量的变化与耐热性正相关,是良好的耐热性筛选指标。

关 键 词:大白菜  高温处理  SOD  丙二醛  可溶性蛋白  叶绿素含量

Abstract:SOD activities,Malondialdehyde contents,soluble protein contents and chlorophyll contents were measured before and after high temperature treatment with six Chinese cabbage parents of hybrid in this experiment.The results indicated that the changes of SOD activities,chlorophyll a and chlorophyll b contents had no relations with the heat tolerance of Chinese cabbage parents of hybrid.So they could not be used as the screening index,the changes of malondialdehyde content and soluble protein content had a marked positive correlation with the heat tolerance of Chinese cabbage parents and they were excellent screening indexes.
Keywords:Chinese cabbage  High temperature treatment  SOD  Malondialdehyde  Soluble protein  Chlorophyll content
