| 摘 要： | 研究了茂县山地生态系统定位研究站人工连香树种群个体种子大小分布及变异。结果表明,连香树种子大小分布呈正态分布,种子大小为(0.4±0.1)mg,其变化范围为0.1~1.2 mg;连香树个体间种子大小存在明显的差异,变异幅度较大,变异系数为31.8%;种子大小变异可能来源于个体间。

| Abstract: | The distribution and variation in seed size of artificial Cercidiphyllum japonicum population were studied in the Ecological Research Station of Mao County.Result showed that the distribution of seed size of C.japonicum was normal.The seed size was(0.4 ± 0.1) mg with the variable range being 0.1-1.2 mg.There were significant differences among the seed sizes of different C.japonicum individuals.The variation range was relatively great with the variance coefficient being 31.8%.The sources of seed size variance was probable the different individuals. |
