摘　　要：以四川省彭州市桂花镇境内一处人工马尾松林中的枹栎为研究对象,对不同个体所产生的果实的相关性状进行分析研究,包括果实长度,宽度及长宽比等指标.研究结果表明该地区枹栎个体产生的果实间有明显差异(p<0.01),枹栎果实大小有较大的变异,果实平均长度和平均宽度分别为(1.85±0.24)cm和(0.93±0.15)cm,变异幅度分别是5.7%和2.3%;果实长宽比为2.01±0.25,变异幅度为6.1%.Pearson相关分析表明,枹栎果实的各性状指标与其母株的长度和胸径没有相关性(p>0.05),枹栎果实大小性状的变异与其在群落中的更新策略有关.Studies and analysis are on the fruit properties of Quercus serrata in Artificial Pinus massoniana Forest in Guihua,Pengzhou,Sichuan Province. The study is on the properties of fruits which come from different individuals （p 〈0.01）. The indexes include fruit length, width and ratio of fruit length to width. The result shows that the fruits from different individuals had significant difference of size. The mean fruit length and width were respectively 1.85±0.24cm and 0.93±0.15cm, the variances were respectively 5.7 % and 2.3 %. The mean ratio of fruit height to width is 2.01±0. 25, the variance is 6.1%. The Pearson correlation analysis resulted that the properties of fruit had no correlation with the height and diameter of the tree （p 〉 0.05 ）. Studies showed that the change of fruit size of Quercus serrata was related to its regeneration in the forest.
