| 摘 要： | 对福建三明市中村采育场9 a生马尾松家系测定林中73个家系、656个单株木材基本密度测定分析结果表明,木材基本密度在家系水平上变异较小,而在个体水平上变异很大;木材基本密度与胸径、材积、圆满度呈极显著的负遗传相关,与轮盘数呈显著的负遗传相关,与通直度呈极显著的正遗传相关;选择木材基本密度较大且生长迅速的马尾松家系和个体是有可能的.

| Abstract: | Wood basic density in masson pine families and individuals were studied based on data of 73 families and 656 individuals from 9 year old progeny plantation of masson pine (Pinus massoniana Lamb.).The results showed that there were small variation in wood basic density at family level and big variation at individual level .The genetic correlations between wood basic density and DBH ,stem volume and branch circle were adverse and very significant, while wood basic density had strong genetic correlation with stem straightness. It was possible to select good masson pine families and individuals with high wood basic density and high yielding. |
