摘　　要：种子大小及其变化不仅涉及到植物生长过程中的生殖模式,而且是植物种的重要适应特征。本文选择了都江堰花溪森林公园内的3种不同生境,以果实长度,宽度,长宽比及重量等作为指标,对不同生境中的常绿阔叶林主要伴生树种枹栎(Quercus serrata)的果实性状进行了研究和分析。结果表明:不同生境间的枹栎果实性状存在差异,但3种生境内枹栎果实各性状指标的变异幅度都不大,果实性状与植株胸径和高度之间没有显著的相关关系(P>0.01),枹栎果实重量与其长度间有明显的相关关系,但果实重量与其宽度及长宽比之间却没有显著相关性。Size and variation of the seed were not only related to reproductive pattern of plant but also the important characteristic of plant adaptation. This article had chosen 3 different habitats in Hua - xi Forest Park of Dujiangyan as the study sites and analyzed the fruit characteristics of evergreen broad - leaved species - Quercus serrata with fruit length, width, aspect ratio and weight as indicators. The results showed a significant difference among the fruits from different habitats, but with small variation range of the fruit characteristics indexes among 3 habitats, and there were no obvious correlation between fruit characteristic and the height and diameter of the plant （ P 〉 0.01 ）. The weight of fruit presented a significant correlation with its length but a non - significant correlation with its width and length/width ratio.
