摘  要：
以江苏地区分布的24个榔榆单株为材料,对其种子表型性状的变异状况进行了研究,结果表明:榔榆单株种子各表型指标存在丰富的变异,且在单株间具有显著差异,单株内变异幅度最大的指标为种子的长径比,而单株间差异最大的指标为种径;榔榆单株种子的种长与种径之间有极显著的相关关系,种径对榔榆种子的形态有较大影响;通过系统聚类分析可将24个榔榆单株分作2类,类C1相比于类C2各单株在种子的种长、种径上较大,在长径比上较小。

摘  要：
In this study,24 individuals of Ulmus parvifolia were selected and the variations among their seeds were analyzed. The results showed that there existed abundant variations in the morphological index of seeds of U. parvifolia individuals,with significant differences between individuals. The seed length-diameter ratio had the max variation within individuals and the seed diameter had also the most significant difference among individuals. There existed significant correlation between length and diameter of seeds of U. parvifolia individuals while seed diameter had great influence in seed morphology.All individuals could be divided into two categories by cluster analysis. Compared with C2,individuals in C1 had larger values in seed length and seed diameter,but small values in seed length-diameter ratio.
