酸枣及17 个枣品种叶片过氧化物酶同工酶的研究

 采用聚丙烯酰胺凝胶垂直电泳, 分析了酸枣和17 个枣品种叶片过氧化物酶同工酶, 并运用相似关系R- 链连接法进行了模糊聚类分析划分了类群, 探讨类群之间的亲缘关系, 从分子水平的表型证实了酸枣是栽培枣的原生种, 其它类群分化程度较大, 进化历史较长, 但都与酸枣有着密切的亲缘关系。

A Study on Peroxidase Isoenzymes of Leaves in Ziziphus spinosus Hu.and Seventeen Varieties of Z.jujuba Mill.

Peroxidase isoenzymes of leaves in Ziziphus spinosus Hu.and 17 varieties of Z.jujuba Mill.were analyzed by means of perpendicular plate type of polyacrylamide gel electrophoresis.Fuzzy cluster analysis was conduc ted based on the similarity coefficients of the isoenzyme zymogram,using the R chain link method of similarity relationship. Z.spinosus Hu.and 17 varieties of Z.jujuba Mill.were classified into several groups.and the relationship among the groups was discussed.From the phenotype of molecular enzyme level,it has been proved that Z.spinosus is the primeval species of the cultivated Z.jujuba, which is the result of a longtime evolution.But both species are closely related to each other.
