| 摘 要： | 以辣椒核雄性不育两用系GMSDS-702A、GMSDS-702B 为试验材料，对其主要农艺性状进行调查，并对花蕾不同
发育时期的相关生理指标的含量进行测定。结果表明，不育系植株的营养生长较旺盛，株高、开展度明显高于可育系；不育
系花药干瘪、表面褐化，组织结构硬化，花药紧闭无法形成正常花粉粒；可溶性糖、可溶性蛋白、游离脯氨酸、丙二醛含量
在不同发育时期的含量均有不同程度的差异，小孢子母细胞期不育系开始表现为可溶性糖、游离脯氨酸含量大幅降低，丙二
醛含量处于较高水平，可育系则相反，可能与小孢子的败育存在一定内在联系。 |

| Abstract: | Taking 2 pepper nuclear male sterile lines‘GMSDS-702A’and‘GMSDS-702B’as experimental material，this paper conducted investigation on their main agronomic traits，and measured the contents of relevant physiological indicators at different development stages of flower buds．The results showed that the vegetative growth of sterile line plant was relatively vigorous．The plant height and spread width were significantly higher than that of the fertile line．The anthers of the sterile line were shriveled，with browned surface，the tissue structure was hardened，and the anthers were tightly closed and could not form normal pollen grains．The contents of soluble sugar，soluble protein，free proline，and malondialdehyde were all different with various degrees at different development stages．At the stage of microspore mother cell，the contents of soluble sugar and free proline in sterile lines were reduced by a big margin，and the content of malondialdehyde was at a higher level．Those of，fertile lines were on the contrary．It might have a certain inner link with the abortion of microspore． |
