摘要
以采自东北林业大学帽儿山实验林场老山生态站的红松人工林内的试材为例 ,分析和探索了红松人工林木材解剖特征的径向变异模式。结果表明 :①管胞长度、长宽比、胞壁率的径向变异模式为 y =a +blnx ,该模型具有典型的生物学意义。②管胞径、弦向直径和壁厚的径向变异为略呈增加趋势 ,径向直径是早材大于晚材 ,弦向直径是晚材大于早材 ;管胞径、弦向壁厚均为晚材大于早材。③管胞径。
Taking the Pinus koraiensis plantation at Laoshan Ecological Station ofMaoershanExperimental Forest Farm, Northeast Forestry University as an example, the author analyzed and explored the radial variation patterns of anatomicalcharacteristics of \%Pinus koraiensis \%wood. The main results obtained are: ① The mathematical models of radial variational regulation of tracheid length, tracheid length-width ratio and tracheid wall percentage wewe y=a+b ln x ,which has typical significance on biology. ②The radial variation patterns of tracheid radial and tangential diameter and wall thickness were positive to growth ring year, radial diameter was early wood>late wood,tangential diameter was late wood>early wood, and tracheid wall thickness was late wood>early wood. ③The radial variation patterns of tracheid wall-indiameter ratio of radial and tangential were not significance.
