| 摘 要： | 采用水平切片淀粉凝胶电泳测定东北地区分布的4 个龙牙木种群的遗传结构。统计分析了10 个酶系统的11 个位点, 结果表明:龙牙木种群内存在着丰富的遗传变异, 多态位点百分率72.73%, 等位基因平均数为1.72, 期望杂合度为0.5617, 遗传一致度和遗传距离为0.9865和0.0133。这个结果与前文对其形态特征和薄层色谱特征分析所得结果基本一致, 充分说明区域龙牙木属于同一种物种的两个变种。 |

| Abstract: | The genetic structures of four Aralia elata population were investigated using the method of horizontal starch gel electrophoresis.Eleven putative loci from ten enzyme systems were statistical analysis. The results showed very high genetic variability in population of Aralia elata, with percentage of polymorplic loci of 72.73%, an average number of alleles perlocus of 1.72, the expected hetrozygote was 0.5617, the meams of Genetic identity and genetic distance were 0.9865and 0.0133.The results are basically in accordance with the results by analysing the characters of morphology and TLC.in the pretext.It indicated that the specimens are two varieties of the same species. |
