Keyword:  板栗木材密度年轮宽度变异;
Abstract: 本文通过对板栗木材密度与年轮宽度的研究表明,板栗木材年轮宽度较窄,为0.21cm,近髓心宽度较大,后期呈较平稳的下降趋势;年轮密度从髓心向外一直呈逐渐下降趋势;平均木材密度为0.6164g/cm3,最大密度为0.7785g/cm3,最小密度为0.3774g/cmn3,早材密度0.4835g/cm3,晚材密度0.6821g/cmn3,变异幅度0.439,密度梯度23.6978,木材面积密度为0.6301g/cm3,在国产商品材中属优良木材.年轮密度与年轮宽度之间的相关系数为0.6821,回归方程为y=0.91x+0.3298.建议板栗在作为经济林培育的同时,可以作为果材兼用林和用材林培育.
