| 摘 要： | 用电子显微镜观察了不育系珍汕97A与保持系珍汕97B的浆片和花丝的超微结构及其在开、闭颖过程中的变化，发现开颖前浆片和花丝细胞的质体中含有淀粉粒，临开颖时，淀粉粒消失。浆片和共丝的薄壁细胞吸水后，内膜系统破裂，释放出水解酶，细胞开始自溶，解体物通过导管等质外体向小穗轴撤离。另外还发现：不育系的浆片中的维管

| Abstract: | The ultramicrostructure of lodicules and filaments and their changes in the process of flower opening and closure in sterile line,Zhenshan 97A and fertile line,Zhenshan 97B were observed under electronmicroscope. It was found that there were some starch grains in the plastids of lodicule and filamen |
