摘要：本文研究了广西人工林马尾松木材性质的变异及幼龄材与成熟材的差异。结果表明 ,幼龄材与成熟材的分界年龄在 14　 16a ,解剖性质在径向上的变异规律为 :射线比量、树脂道比量、胞壁率、胞腔直径、胞壁厚、管胞长度、管胞宽度和晚材壁腔比是自髓心向外呈递增趋势 ,管胞比量和晚材率为递减趋势 ,早材壁腔比和早材腔径比则近似于一条直线。方差分析结果表明 :树脂道比量、胞壁率、胞壁厚、管胞长度和管胞宽度 ,幼龄材与成熟材差异达显著或极显著水平。 5项木材物理力学性质均为成熟材高于幼龄材 ,且均达差异显著水平。木材性质间的相关分析表明 :木材基本密度与管胞长度、管胞宽度、射线比量、树脂道比量、胞壁率呈显著的正相关关系 ,木材气干密度与抗弯强度、抗弯弹性模量。
The variation in wood properties and the differences between juvenile wood and mature wood of Masson Pine( Pinus massoniana ) plantation from Guangxi were studied. The results are as follows: The boundary between juvenile and mature wood was delimited at the age of 14～16 year. The radial variation patterns of the anatomical properties from pith to bark are: the ratio of ray tissues, ratio of resin canal, cell walls percentage, lumen diameter, wall thickness of tracheid, tracheid diameter, tracheid length, ratio of wall to lumen (latewood) increase with the increase of growth ring, while ratio of tracheid and ratio of lumen to diameter decrease with the increase of growth ring. Most parameters of the anatomical properties of mature wood are higher than that of the juvenile wood with significance level shown in ratio of resin canal, cell walls percentage, wall thickness of tracheid, tracheid diameter, tracheid length. All of the physical and mechanical properties of mature wood are higher than that of juvenile wood significantly. Analysis of relationship showed that the ratio of ray tissues, ratio of resin canal, rate of cell wall, tracheid length were positively correlated to wood density with significance level. The MOR, MOE, and crushing strength were positively correlated to wood density significantly in juvenile and mature wood.
