摘　　要：采用实测法对6个种源的红花天料木幼苗生长量进行连续测定和综合分析,结果表明:不同种源间苗期生长量差异显著,乐东1种源的幼苗生长较好。通过变异系数分析发现,变异系数分别为:地径为0.53,苗高为0.44,说明不同种源间的地径变化幅度比较大。The seedling biomass of six provenances of Homalium hainanense was tested by the continuous measurement and comprehensive analysis. The results showed that the seedling growth was significantly dif-ferent in different provenances. The growth performance of Ledong 1 provenance was better than the others. The variation coefficient of ground diameter and seedling height was 0.53 and 0.44,respectively,indicating that the variation range of the ground diameter was larger between different provenances.
