| 摘 要： | 采用ISSR标记技术,对8种桦树(Betula)进行了亲缘关系的分析,17个ISSR引物共检测到236个位点,多态条带比率(PPB)在5.93%～19.92%之间,遗传分化最高的是油桦,最低的是棘皮桦。8种桦树的基因多样性(Ht)为24.38%,桦树种间变异占总变异(Gst)的79.36%。遗传距离聚类将8种桦树分为3个群,黑桦、油桦、白桦和欧洲白桦为一群;赛黑桦、枫桦和岳桦为另一群;棘皮桦单独为一群。聚类结果与传统的形态分类一致。图2表4参10。

| Abstract: | Genetic relationships of eight species of genus Betula were evaluated using ISSR marks. A total of 236 loci were generated from 17 ISSR primers. Percentage of polymorphic bands (PPB) varied from 5.93 to 19.92. The highest and the lowest level of genetic differentiation were detected in B. ovalifolia and B. maximowicziana Regel respectively. In these eight species, genetic diversity of birch (HT) was 24.38 %, and the genetic variation (GST ) interspecies was accounting for 79.36% of total genetic variation. According to the cluster results of genetic distance, the eight species were classified into three groups as B. davurica, B. ovalifolia, B. platyphylla and B. pendula for one group; B. schmidtii, B. costata and B. ermanii Cham. var. communis for one group, and B. maximowicziana Regel for another group. The result of cluster is consistent with traditional morphological classification. |
