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 of wood quality of Pinus densiflora var. Mongolica was studied and analyzed by using the method of growth wheel material analysis. The mathematical models of the radial variation of tracheid length, tracheid width, tracheid length and width ratio, growth wheel basic density, growth wheel width, latewood and growth rate were obtained. Correlation test showed that most of the woody material indicators were significantly correlated with the growth ring.
