| 摘 要： | 对小桐子8个居群种子表型进行研究,测量种子长度、宽度、重量等11项形态学指标。种子表型性状,居群间的变异系数c.v.%=10.64~19.33,表型频率分化系数平均Pst=10.02%,表型方差分化系数平均Vst=14.27%,表明小桐子种子表型居群内变异是其变异的主要来源。居群间欧氏距离Q-聚类分析表明,种子表型分化基本与居群间的地理距离远近相关联。11个表型性状间多数呈极显著或显著的正相关,种子长度、宽、厚、周长和种子百粒重为小桐子易测定和重要的表型性状。 |

| Abstract: | The seeds were collected from 8 populations of Jatropha curcas L..Based on the data of 11 seed phenotypic traits,the phenotypic differentiation of seeds was studied in the 8 populations sampled.The phenotypic traits of seeds showed a certain differentiation among populations of J.curcas.The average coefficient of variation ranged from 10.64 % to 19.33 % among the populations sampled,with the mean variation differentiation coefficient of phenotypic trait(Vst) being 14.27 %.The mean frequency multiplicity coe... |
