| 摘 要： | 试验对耐热性不同的2个甘蓝品种的种子进行了热激处理,在苗期测定了热激处理对甘蓝叶片中保护酶活性和膜透性的影响。结果表明,热激处理后,耐热品种叶片中超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)活性的增幅大于不耐热品种,而不耐热品种叶片中丙二醛(MDA)的含量和膜透性的增幅大于耐热品种。

| Abstract: | The heat shock treatment was conducted on the seeds of two cabbage(Brassica oleracea L) varieties with different heat-resistant ability,and the activity of leaf protect enzymes and membrane permeability were tested in seedling stage.The results showed that,after heat shock treatment,the activity of SOD,CAT,and POD in the leaves of heat-resistant variety had a higher increase than in the heat-sensitive variety;and the increase of MDA and membrane permeability was higher in the heat-sensitive variety than in the heat-resistant variety. |
