自甜菜质核互作型雄性不育现象发现后,各国学者对其不育机理,从遗传学、细胞生物学、生物化学方面做了大量研究工作。细川定治发现不育甜菜氨基酸组成中缺少脯氨酸,而丙氨酸却比保持系含量高,在形态学上Arsthwager发现毡绒层的不正常是甜菜雄性不育的原因。这些研究成果加深了我们对甜菜雄性不育的认识。本试验作为甜菜雄性不育研究的一部分,目的在于利用聚丙烯酰胺电泳法,研究不育系与保持系之间过氧化物酶同工酶的关系,为探讨甜菜雄性不育产生原因积累资料。 Since the discovery of nuclear-type male sterility in sugar beet, scholars from various countries have done a lot of research work on genetics, cell biology and biochemistry. Hosokawa found that there was a lack of proline in the amino acid composition of the sterile sugar beet, whereas the content of alanine was higher than that of the maintainer line. Morphologically, Arsthwager found that the abnormality of the melon layer was the cause of male sterility of sugar beet. These findings have deepened our understanding of beet male sterility. As part of the research on the male sterility of sugar beet, the purpose of this study is to study the relationship between the isoenzyme peroxidase between the male sterile line and the maintainer line using polyacrylamide electrophoresis, and to accumulate data to explore the causes of the male sterility of the sugar beet.
