【摘要】 以国产决明属(Cassia)4种植物为实验材料,采用愈创木酚法和聚丙烯酰胺垂直板凝胶电泳对其抗逆指标和过氧化物酶(POD)同工酶进行测定,分析其系统树与传统决明属系统分类之间的差异。结果表明:发芽1天的过氧化物酶活性和3天的MDA含量差异显著,可作为探讨其亲缘关系的指标之一。发现POD同工酶带12条,4种决明没有共同拥有的条带,决明属植物的特征性酶带主要分布在b区和a区。与传统分类不同,抗逆指标和同工酶分析结果都表明,槐叶决明(Cassia sophera)与豆茶决明(C.nomame)亲缘关系最近,翅荚决明(C.alata)次之,决明(C.tora)与其他种亲缘关系最远,属于另一支。

【Abstract】 In order to draw a phylogenetic tree of 4 species of Cassia in China,the study used guaiacol method and polyacrylamide vertical slab gel electrophoresis to test the resistance indicators and peroxidase isozyme,and analyzed the differences between the result and traditional systematics.Peroxidase activity of 1 day,MDA of 3 days significantly differed among species,so it can be used as one of the indicators to explore their genetic relationship.12 POD enzyme bands were found,characteristic enzyme bands were mainly in b-zone and a-zone.Differed from traditional systematics,both resistance indicators and POD zymogram revealed that Cassia sophera was closer to C.nomame than C.alata in systematics,while C.tora belonged to another branch.
