【Abstract】 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.更多还原
