东北红豆杉天然群体过氧化物同功酶的遗传多样性

Genetic diversity of peroxidase isozyme about natural population of taxus cuspidata

东北红豆杉天然群体内的多态位点比例（Ｐ） 为０ ．６７ ，平均杂合度（ Ｈｅ） 为０ ．３３３ ，居群遗传变异型为ＨＴ＝ ０ ．４４４ 和Ｇｓｔ ＝ ０ ．１６９ ．即总的基因多样性８３ ．１ ％ 来自群体内，１６ ．９ ％ 来自群体间．取自黑龙江穆棱的群体遗传性远离其他群体，建议加强该群体与其他群体间的基因交流．

There is higher genetic diversity in population and among populations.Proportion of polymorphic site(P)is 0.67,average hetevozygosity(He) is 0.333.Genetic variation type is H T=0.444 and Gst=0.169.There is 83.1% of total genetic diversity in population,and another 16.9% is among populations.The genetic population coming from Heilongjiang Muling is distinct about other population.We suggest that should enhance genetic exchange between the population and other population.
