摘　　要：以水稻红莲型细胞质雄性不育(HL-CMS)的不育系粤泰A(YTA)、保持系粤泰B(YTB)以及杂种F1代红莲2号(HL2)的黄化苗提取的线粒体为材料,对其线粒体膜的流动性及线粒体膜的丙二醛(MDA)含量进行分析,结果表明杂种F1代HL2线粒体膜的流动性最强,而且线粒体膜MDA的含量最低,不育系YTA线粒体膜的流动性相对最弱,同时线粒体膜MDA的含量最高。HL-CMS的不育性可能与HL-CMS水稻线粒体膜的流动性及线粒体膜的MDA含量有关。In this paper, a comparison of the mitochondrial membrane fluidity (MMF) and the content of malondialdehyde(MDA)between Honglian cytoplasmic male sterility (HL-CMS) line, which is a novel source of germplasm in China, Yuetai A (YTA), its maintainer line, Yuetai B (YTB), and the hybrid, HL2, was carried out. The results showed that MMF of HL2 is the strongest,and its MDA content is the lowest among the three materials used. The sterile line, YTA, however, is contrary to HL2, having the lowest MMF and highest MDA content. It indicated that the changes of MMF and MDA content might be related to CMS.
