摘要
用生长轮材质分析方法研究和分析了天然林赤松木材材质的变异规律．得出了管胞长度、管胞宽度、管胞长宽比、生长轮基本密度、生长轮宽度、晚材率、生长率7项材性指标径向变异规律的数学模型。相关性检验表明,多数材性指标均与生长轮有显著相关性。
The variation Pattern of wood properties of natural Pinus densiflora was studied by growth-ringmethod for analyzing wood properties. The mathematical models for property parameters on tracheidlength, tracheid width. ratio of tracheid length and width. growth-ring basic density, growth-ring width.latewood Percentage and growth Percentage in the radial direction were set up. The results of correlationanalysis showed that except the density. the other six indices are all significantly related to the growth ring.
