| 摘要: |
| 对广东省16个木荷群体叶片表型性状进行测定分析，结果表明：叶片长、叶片宽、叶面积、长宽比、叶脉数和叶脉密度6个性状在群体内和群体间的差异均达极显著水平(P＜0.01)；木荷叶片6个表型性状在群体间的平均表型分化系数为11.44%，在群体内的平均表型分化系数为88.56%，说明群体内变异是木荷叶片表型变异的主要来源。 |

| Abstract: |
| The leaf morphologic characteristics of 16 Schima superba populations were investigated in Guangdong Province. The results showed that variations of all the morphologic traits within population were significant, and significant differences existes in 6 character indices among populations (P＜0.01). The phenotypic differentiation co-efficient of 6 character indices was 88.56% within population and 11.44% among populations. The results suggested that the phenotypic variation within population was the main component of the variation in this species． |
