| 摘 要： | 利用红松种子的单倍体胚乳，采用水平切片淀粉凝胶电泳技术，对采自三个地区的天然红松林的材料进行了１０种酶系统的等位酶实验，共获得了１８个等位基因位点，对这１８个位点等位基因的统计分析表明：红松种群的多态位点百分数为Ｐ＝７７．７８％，等位基因平均数为Ａ＝２．０，预期杂合度为Ｈｅ＝０．１６４８。红松种群间遗传分化程度在松属于较低水平。在红松１８个等位基因位点的变异中，绝大部分变异９４．２％来自种群内部，

| Abstract: | Ten enzyme systems were tested for the endosperm of korean pine from three populations using the horizontal starch gel electrophoresis technique. 18 loci were obtained. The results indicated the ratio of polymorphic loci was 77.78%, the average number of alleles was 2.0(A) and the expected heterozygous was 0.1648(He). The genetic differentiation (Gst=5.38%) among populations was lower than other species in Pinus genus and most variations were within population. According to Nei's index, the genetic distance (0.0095) between Xiaobeihu and Changbai Mountain was nearest, not correlation to the geographical distance. It shows the original complexity of population. |
