摘要:
 以北京、河南和陕西不同产地的栓皮栎、麻栎、锐齿栎、房山栎、辽东栎、蒙古栎、夏栎、沼生栎等8种落叶栎类种子为研究对象，测定每粒种子的重量、种长、直径、包被长、碗疤直径和体积等形态指标，分析了不同种类、不同产地种子形态差异以及种内各因子之间的相互关系。结果表明：8种落叶栎类种子百粒重、长度、直径、体积、包被长和碗疤直径平均值分别为(266.18±80.23)g、(20.70±1.51)mm、(14.65±2.07)mm、(2.82±0.91)cm3、(8.90±2.27)mm和(9.93±2.02)mm，不同种类、不同产地、不同个体栎类种子形态指标差异明显，指标间相关性较强；因子分析提出了落叶栎类种子3个公因子分别为：与直径相关的指标、与包被长相关的指标以及与种长相关的指标。为植物数量分类及相关研究提供参考。
