摘要
以10个甜(辣)椒品种为参试材料,以茄门(不耐低温弱光对照,CK1)和湘研1号(耐低温弱光对照,CK2)为对照材料,在低温弱光条件下,研究了幼苗叶片抗氧化酶活性与质膜透性的变化。结果表明:参试材料中8个品种耐低温弱光性较强,其顺序为:AB91-XB>冀研16号、JF8G-2-1-2-5-1-11-4>冀研28号、AB91-W222-49176>HPJ-2-2-1-2-1、BYT-4-1-3-6-8、AB91-LH-51217;耐低温弱光较强的品种SOD、POD和CAT活性相对较高,而MDA含量和质膜透性相对较低且变化幅度较小。
Using ten sweet（ hot） pepper varieties as materials with Qiemen（ not resistant to weak temperature and low light,CK1） and Xiangyan 1（ resistant to low temperature and weak light,CK2） as controls,the changes of anti- oxidative enzyme activities and plasma membrane permeability of seedling leaves were studied under low temperature and weak light. The results showed that eight varieties had strong tolerance to low temperature and weak light with the order of AB91- XB 〉Jiyan 16,JF8G- 2- 1- 2- 5- 1- 11- 4 〉Jiyan 28,AB91- W222- 49176 HPJ- 2- 2- 1- 2- 1,BYT- 4- 1- 3- 6- 8,AB91- LH- 51217.And the varieties with strong tolerance to weak light and low temperature had relatively higher SOD,POD and CAT activities. But their MDA activity and plasma membrane permeability were relatively lower with little changes.
