摘要：以采自中国东南部亚热带7个种群的210棵单株的叶、果实和种子的12个形态指标作为研究对象,运用变异系数、巢式方差分析、相关分析揭示浙江柿(Diospyros glaucifolia)表型遗传变异规律和变异程度,并且运用聚类分析进行了居群分类。结果表明:浙江柿种内表型性状在群体间和群体内存在极其丰富的遗传差异,群体内的多样性程度高于群体间的多样性,而且种子性状在群体间较稳定。12个表型形状相关性不显著,浙江柿种居群表型变异在空间分布上主要呈现以纬度和海拔为主的单向变异模式,利用欧氏平均距离聚类分析,基本可将浙江柿7个群体可划分为5个类群。
12 phenotypic traits from leaves,fruits and seeds were investigated for 210 individuals in 7 natural populations of Diospyros glaucifolia from south-east China and the relationship between phenotypic variation of the natural populations and different distribution areas was discussed using variance analysis and nested variance analysis. The relationship among phenotypic variation of the natural populations, geo-ecological factors and morohlogical traits was discussed by correlation analysis. The results showed that there were significant differences in phenotypic variation among and within populations. It also showed that the diversity within populations was higher than that among populations. The average differentiation coefficient of seed traits is the smallest in all phenotypic traits.The traits stability of seeds was higher than that of other traits. There was no significant relationship between traits. The traits variation of natural populations were affected mainly by longitude （such as LL and LW） and height（such as seeds weight） in spatial distribution. The 7 populations investigated could be divided into five groups according to the cluster analysis.
