Abstract

Genetic variation and geographical diversity of five natural populations of Cryptomeria japonica in western Japan were investigated for nine allozyme loci. Genetic variation of this species was somewhat lower than the other coniferous species. Most of the variation was attributable within population (98.16%) rather than between populations (1.84%). The GST value was only .0156 and genetic distances between populations were also small, averaging .0062. These results indicate that natural Cryptomeria forests in western Japan have maintained relatively middle genetic variation, comparing with the other conifer species, but these populations were not genetically differentiated each other.

日本西部柳杉5个自然居群的等位酶变异
对日本西部柳杉5个自然居群的9个等位酶位点的遗传变异和地理多样性进行了研究。本种的遗传变异略低于其他针叶树种。大部分变异可归因于群体内(98.16%),而非群体间(1.84%)。GST值仅为0.0156,居群间遗传距离也较小,平均为0.0062。这些结果表明,日本西部天然柳杉林与其他针叶林相比,保持了相对中等的遗传变异,但这些居群之间没有遗传分化。
