马尾松优树子代材性的初步研究

Preliminary Study on Wood Properties of Plus Tree Progenies of Masson Pine

本文通过对４３个马尾松优树子代１０年生时的材性进行初步分析，结果表明：（１）木材相对密度在家系间存在显著的差异，而纤维素含量则差异不显著；（２）对马尾松材性的选择，除了应利用家系间差异外，还应注重家系内个体间的选择；（３）进行马尾松纸浆材家系选择时，应以生长量为主、材性为辅。

By means of the preliminary analyses of wood properties of 43 10 year old plus tree progenies of masson pine,the results show that the difference among families in wood relative density is obvious while it is not clear in the aspect of the content of cellulose;for the wood property selection,the difference among families should be used and the selection among individuals within each family should be also attached importance to;and when the selection of paper pulp wood families of masson pine is conducted,the growth should be as a major index whereas the wood properties should be as an auxiliary one.
