结球白菜同核异质雄性不育系同工酶研究

采用聚丙烯酰胺凝胶电泳法，研究了具有甘蓝型油菜胞质、萝卜胞质的结球白菜同核异质雄性不育系－Ｐｏｌｃｍｓ３４１１－７，Ｏｇｕｃｍｓ３４１１－７及其保持系３４１１－７不同发育时期，不同器官过氧化物酶同工酶谱的差异。结果表明，不育系与保持系过化物酶同工酶谱的差异主要在花蕾中，表现为不育系酶带多而且活性强，其它器官差异较小；Ｐｏｌｃｍｓ３４１１－７与Ｏｇｕｃｍｓ３４１１－７的区别在苗期、蕾期、花期及叶片、

The Peroxidase Isoenzyme Differences among Allocytoplasm Male Sterile Lines and Their Maintainer of Chinese Cabbage

The differences of peroxidase isoenzyme among the two allocytoplasm male sterile lines with the same nucleus (AA, Zn=20) (Polcms3411-7 and Ogucms3411-7) and separately by transferred ms of Brassica napus (Polima, Shiga, 1980) and ms of Raphanus sativus (Ogura, 1968) to Chinese cabbage (B. campestris ssp. pekinensis) and their common maintainer (3411-7, AA, 2n=20) at different developmental stages and organs were studied by using polyacrylmide gel electrophoresis, the main results obtained are as follows:The differences between the two CMS lines and their maintainer existed in the flower buds, especially in the bigger buds; there were more band numbers in the CMS lines than the maintainer and these bands were more active.The differences between Polcms3411-7 and Ogucms3411-7 existed in all the developmental stages and organs.
