对辣椒雄性不育系9704A及其保持系9704B的花药发育过程进行了显微结构和超微结构观察。结果表明：保持系9704B的绒毡层属于腺质型；不育系9704A的成熟花药的药隔维管组织发育正常，该不育系属于孢子体败育型，花药绒毡层细胞的核膜在花粉母细胞的细线期消失，核裂解成块分散到细胞质中，并最终消失，解体后的绒毡层类似于变形型绒毡层的周原质团进入花粉囊，渗入花粉母细胞周围，并与花粉母细胞粘连在一起，使花粉母细胞不能继续进行减数分裂形成四分体，花药的中层细胞不退化。

The anatomical observations were conducted on anther development of 9704A, a cytoplasmic male sterile line in Capsicum annum L. , and its maintainer line 9704B. The results showed that the taptum of the maintainer line belonged to the glandular type. The development of vascular tissue in the connective of the CMS lines was normal, the abortion type of this CMS line was sporophyte abortion, the karyotheca of the tapeturn ceils of the CMS line vanished at the sporogenous cell stage, then the nucleus lysed and dispersed into cytoplasm agglomerately and vanished ultimately. The disintegrated taptu...
