本研究就国营雷州林业局尾叶桉 U6无性系立木木材密度与吸水率的关系作了探索和分析。结果表明：两者呈极显著负相关，即密度越大吸水率越小，其相关系数为：r=-0.9237；回归方程的估测精度为99.01%，高达一级精度水准，回归方程本林区适用；同时发现尾叶桉 U6立木木材不同高度的密度、吸水率的差异性是极显著的；生长在不同土壤类型的立木木材密度和吸水率也存在着差异。

In this paper the relationship between the density of wood obtained from Eucalyptus urophylla hybrid clone U6 and the rate at which this absorbs water were studied. The results revealed a strong negative relationship between these parameters with a highly significant correlation (r = -0.923) indicating that the higher the wood density the lower its water absorption rate. A regression equation for predicting water adsorption based on wood density had the same correlation coefficient and an estimated accuracy of 99.0%. It was also found that the wood density and the rate at which this can absorb water, varied markedly with height within the trunks of trees of clone U6. With different soils types, tree growth was found to differ markedly as did both wood density and the rate at which wood from the trees can absorb water.
