摘要
对福建省五一林场的马尾松种子园开花习性进行了观测和分析，结果表明无性系间和年度间的雌雄球花量差异达极显著水平；且雌雄球花量在年度间亦达显著相关。另外还分析了各无性系的雄球花贡献率及对子代贡献率较大的无性系。
The strobile habits of clones in Wu Yi seed orchard of masson pine( Pinus massoniana ) were observed. The results showed that variation between clones and years of females cones and males cones were the more signficance. So as the relationship between years. In addition,the contribition to progenies of the female were analyzed. The various clones made different contribution to progenies.
