摘　　要：采用等位酶电泳技术，检测了青岛近海岛屿———长门岩岛、大管岛和浙江普陀山的天然山茶居群的遗传状况，并与青岛植物园和杭州植物园的栽培山茶居群作了比较。分析结果表明：青岛近海岛屿山茶居群内的遗传多样性水平较高，每个位点的等位基因平均数为２３，多态位点比率为８３３％，平均观察杂合度与期望杂合度分别为０２４５及０３２０，这个结果可以为青岛耐冬山茶的保护提供依据。为了探讨形态分化与等位酶变异之间的关系。Allozyme electrophoresis was applied to the genetic diversity analysis of wild Camellia japonica populations on Qingdao off shore island Changmenyan Island, Daguan Island and of Putuo Mountain in Zhejiang Province, as a comparison, two cultivated camellia populations in Qingdao Botanical Gardens and in Hangzhou Botanical Gardens were analyzed. The result showed that the genetic diversity within island camellia population is high, the mean number of alleles per locus is 2 3; 83 3% of loci are polymorphic on average per population; the mean observed and expected heterozygosities are 0 245 and 0 320 respectively. The result suggested strategies for the conservation of camellia in Qingdao. Allozyme phenotypes of different morphological types were compared in order to find some relationships between morphological variation and allozyme diversity.
