摘　　要：以2份辣椒核型雄性不育两用系为试材，对不育株与可有株小孢子不同发育时期花药的部分生化特性进行了比较分析，并初步探讨了这些生化特性的异常与不育性表达之间的关系。结果表明：花药中的过氧化物酶活性从小孢子母细胞期以后不育株明显高于可育株，过氧化氨酶活性从小孢子母细胞时期开始不育株明显低于可育珠；可溶性蛋白含量从小孢子母细胞期以后不育株明显低于可育株。Comparison and analysis were made on a few biochemical characteristics during the stages of microsporogenesis, between the fertile and the sterile plants that genic male sterile pepper (Capsicum annuum L. ) AB154 and AB1691. At the same, the relation of the abnormity of biochemical characters with the expression of sterility were also studied. The results showed that anthers of the sterile plants revealed significantly higher peroxidase (POD) activities but lower catalase (CAT) activities begining from the stage of microsporocyte. After that stage, the soluble protein contents in anthers of the sterile plants were distinctively lower than that of the fertile ones.
