摘要
研究了甜椒(Capsicum annuumL.)胞质雄性不育系(CMS)T6A和保持系T6B的可溶性糖、可溶性蛋白质含量以及超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性的变化。结果表明:无论是在叶片中还是在花药中,不育系可溶性糖含量、可溶性蛋白质含量、CAT活性均低于其保持系;SOD和POD活性则高于其保持系。这说明上述物质含量和酶活性变化可能与甜椒CMS T6A的不育有关。
A comparison of soluble sugar and protein content, activites of superoxlcle olsmutase （SOD）, peroxidase （POD） and catalase （CAT） between cytoplasmic male sterile line （CMS） T6A and its maintainer line T6B of sweet pepper （ Capsicum annuum L. ） in different developmental stages of leaves and buds were carried out in this study. The content of soluble sugar and protein and the activity of CAT were low in both leaves and buds and the activities of SOD and POD were high in CMS than those in its maintainer line. These results suggest that the variation of soluble sugar and protein content and enzyme activities used contribute to pollen abortion in CMS T6A.
