| 摘 要： | 从湿地松×洪都拉斯加勒比松Ｆ１和Ｆ２各１５个家系中取样，测定和分析其木材基本密度发现，Ｆ１和Ｆ２木材全木芯基本密度的总平均值间没有显著差异，木材密度的变幅Ｆ２比Ｆ１的略大，而幼龄材与成熟材的基本密度之间的差异Ｆ２比Ｆ１小。

| Abstract: | From two generations, F 1 and F 2, of slash pine and Honduras Caribbean pine hybrid, fifteen families each were sampled for studing and inspection of their wood basic densities. There was no obvious difference between the F 1 and F 2 hybrids in the overall mean of basic density for the whole core. The distribution in the measured basic density of the F 2 was a bit larger than that of the F 1. However, the variation of wood basic densities between the juvenile and mature of the F 2 was much smaller than that of the F 1. |
