缙云山华南黑桫椤种群的遗传多样性研究初探

A Preliminary Study on the Genetic Diversity of Gymnosphaera Metteniana in Jinying Mountain

从种群分化和保护生物学的角度出发,运用方差分析和聚类分析,对缙云山不同生境下的8个华南黑桫椤种群的形态分化进行研究,方差分析表明该种的形态特征对环境的可塑性较大,繁殖器官的变异小于营养器官,聚类分析表明8个种群间总体上无明显分化.

Using the variance analysis and cluster analysis, morphological differentiation of 8 Gymnosphaera metteniana were studied. Variance analysis shows that most of the studied morphological characters vary significantly between the populations. The reproductive organs change less than vegetative organs among the different environments. Cluster analysis shows that 8 populations have not significantly differentiations in general.
