玉兰属20种植物过氧化物同工酶研究

为进一步检验玉兰属植物酶谱分类的可靠性,采用聚丙烯酰胺凝胶电泳系统测定了该属20种植物的过氧化物同工酶酶谱,并用排序方法对它们酶谱综合因子的相似程度进行了分析.结果表明,该属20种植物的过氧化物同工酶酶谱均有显著差异,每种均有特征酶谱或以酶谱因子不同相区别.它们酶谱综合因子的排序结果与其形态分类相吻合,从而为该属植物物种鉴定、良种选育及其属下分类系统建立提供了酶学依据和手段.

Peroxidase Isozymes of 20 Species of Yulania Spach

In order to verify the reliability of zymogram classification,the peroxidase isozymes of 20 species of Yulania Spach have been analysed by polyacrylamide gel electrophoresis,and a taxis method is used to analyze the similar degree of integrative factors of its' zymograms.The results indicate that each of species,varieties or cultivars of Yulania Spach has itself specific zymogram or zymogram factors.And the taxis results tally with those of morphological classification.So this method provides an enzymology basis and means for identification and selection of cultivars,and for the establishing of classification system of Yulania Spach.
