摘要
研究分析了人工林与天然林赤松木材的管胞长度、管胞宽度及管胞长宽比等管胞形态特征和生长轮基本密度的径向变异 ,结果表明 ,人工林与天然林赤松木材的管胞长度差异不显著 ,管胞宽度。
The variations of wood tracheid length, tracheid width, ratio of tracheid length and width and basic density of Pinus densiflora plantation and natural forest were studied in this paper. The results showed that there is no distinct difference in wood tracheid length between Pinus densiflora plantation and natural forest, while there is distinct difference in wood tracheid width, ratio of tracheid length and width and basic density between Pinus densiflora plantation and natural forest.
