摘要：以国外引种舒氏红栎(Quercus shumardii)和黑栎(Q. nigra)活立木为研究对象,利用生长锥获取木芯,分析其基本密度径向变异规律,并探究树木针测仪(Resistograph)评估两种木材不同部位基本密度的可行性。结果表明,两种栎树的生长轮宽度从髓心至树皮方向呈下降趋势,基本密度从髓心至树皮方向呈上升趋势;利用Resistograph检测的平均振幅值可对舒氏红栎和黑栎木材的基本密度进行评估,拟合结果均达到统计学上的显著水平,且二者均是近树皮段的拟合度较高,舒氏红栎的相关系数为0.821,黑栎的相关系数为0.743。研究结果可为间接评估舒氏红栎和黑栎木材基本密度提供理论依据。
This study focuses on the standing trees of Quercus shumardii and Q.nigra,which were introduced from overseas.Growth cones were used to collect wood cores.The basic density and radial variation patterns were analyzed.Additionally,the Resistograph was employed to predict the basic density from different wood sections in Q.shumardii and Q.nigra.The findings revealed that the annual ring width of Q.shumardii and Q.nigra exhibited a decreasing trend from the pith to the bark,while the basic density increased in the same direction.The Resistograph effectively assessed the basic density of Q.shumardii and Q.nigra respectively.Notably,the accuracy of the fit was highest for wood located closest to the bark,with correlation coefficients of 0.821 and 0.743,respectively.This research provides a theoretical foundation for the efficient assessment of basic wood density in Q.shumardii and Q.nigra.
