Abstract

Abstract: A comparison of soluble sugar and protein content, activites of superoxide dismutase ( 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.

Key words: Sweet pepper, Cytoplasmic male sterile line (CMS), Maintainer line, Soluble sugar, Soluble protein, Activity of enzyme
