以辣椒细胞质雄性不育突变体CMS102及其相应的恢复系ST-8为材料,对其造孢期、小孢子母细胞期、小孢子减数分裂期、四分体时期、单核小孢子期、双核小孢子期和花粉粒成熟期的花蕾进行细胞学形态观察,测定小孢子减数分裂期、四分体时期、单核小孢子期和双核小孢子期发育时期的花蕾中与育性相关的生理活性物质的含量。结果表明:CMS102败育发生在四分体时期,绒毡层过度膨大挤压四分体,使其不能正常发育成单核小孢子,属于孢子体不育;CMS102花蕾中可溶性蛋白和游离脯氨酸含量低于ST-8的,可溶性糖、 MDA含量及POD酶活性高于ST-8的;构建F2遗传分离群体并调查其育性,对CMS102的育性进行遗传学分析,CMS102...

The cytoplasmic male sterile line CMS102 and the restorer line ST-8 of capsicum were used as materials.The anther cytological morphology of flower buds in sporogenic stage,microspore mother cell stage,microspore meiosis stage,tetrad stage,uninucleate microspore stage,binucleate microspore stage and pollen maturity stage were observed.The contents of physiologically active substances related to fertility in flower buds in microspore meiosis stage,tetrad stage,mononucleate microspore stage and binucleate microspore stage were determined.The results showed that CMS102 abortion occurred in the tet...
