摘　　要：The effectiveness of pilodyn was tested in evaluating wood basic density, outer wood density, heartwood density, and modulus of elasticity （MoE） at 22 four-year-old eucalyptus clones in Guangxi, China. Results indicated that the mean value ranged from 9.44 to 15.41 mm for Pilodyn penetration, 0.3514 to 0.4913 g.cm^-3 for wood basic density, and 3.94 to 7.53 Giga Pascal （GPa） for MoE, respectively. There were significant differences （1% level） in pilodyn penetration between different treatments, different directions and among the clones. Generally strongly negative correlations were found between pilodyn penetration and wood properties, and the coefficients ranged from -0,433 to -0,755. Our results, together with other studies, suggest that the use of pilodyn for assessing wood density and MoE was confirmed as a possibility.测定了建立在广西22个4年生按树无性系的Pilodyn值、木材基本密度、边材木材密度、心材木材密度和弹性模量。结果表明:Pilodyn值为9.44-15.41mm、木材密度为0.3514-0.4913g·cm-3、弹性模量在3.94GPa到7.53GPa之间;Pilodyn值在不同处理、不同方向及不同参试无性系间均存在极显著差异。Pilodyn值与各材性指标间的相关系数在-0.433到-0.755之间,呈显著到极显著负相关。研究表明,Pilodyn方法可以预测桉树活立木的木材密度和弹性模量。表6参28。
