福建省杉木人工林材性产区效应的研究 Ⅰ.木材基本密度和纤维形态

Wood Properties of Chinese Fir Growing in Different Production Regions Ⅰ Basic density and fiber morphology

通过对福建省不同产区杉木人工林木材基本密度和纤维形态的测定和分析，结果表明杉木人工林木材基本密度和纤维形态的产区间效应大于产区内效应，产区间木材基本密度和纤维形态差异极显著，产区内木材基本密度和纤维形态差异不显著；杉木人工林木材基本密度表现为：边缘产区＞一般产区＞中心产区；纤维长度和长宽比表现为：一般产区＞边缘产区＞中心产区；纤维宽度表现为：中心产区＞一般产区＞边缘产区．

Basic density and fiber morphology of Chinese fir wood sampled from different production regions were determined and analyzed These two measures exhibited greater differences among production regions(with significant differences) than within production region(no significant differences) Basic density of wood from different production regions decreased in the order: boundary>ordinary>central production region; fiber length and length/width ratio: ordinary>boundary>central production region; fiber width: central>ordinary>boundary production region
