摘　　要：对缙云山3个群落类型(毛竹林、针阔混交林和常绿阔叶林)的川鄂连蕊茶种群的形态变异进行了初步研究。3个种群种子的平均单粒重量分别为0.416g,0.443g和0.393g,种群间差异不显著。Gini系数分析表明种群内种子的变异主要来源于各单株内部,可能是种子在树冠中所处部位的不同造成的。The morphological variation of seeds of Camillia rosthornina populations in three communities (giant bamboo forest ?mixed conifer-broad forest and evergreen broadleaved forest)in Mt. JinYun was studied. The mean seed mass of three C. rosthornina populations was 0.416 g,0.443 g and 0.393 g respectively, no significient variation was found among populations. Gini coefficient analysis showed that the variation of intrapopulation mainly comes from the variation of intraplants, which was perhaps caused by its position in crowns of parent tree.Key words:Community; Camillia rosthornina Population; seed; morphological variation
