研究分析了不同林分人工林赤松木材的生长轮基本密度和管胞长度、管胞宽度及管胞长宽比等管胞形态特征的变异。结果表明 :赤松纯林和赤松与沙松混交林中赤松木材的基本密度、管胞宽度存在显著差异 ,赤松纯林中赤松木材的基本密度比赤松与沙松混交林中的高 ,赤松与沙松混交林中赤松木材的管胞宽度比赤松纯林中的大 ,而赤松纯林和赤松与沙松混交林中赤松木材的管胞长度和管胞长宽比差异不显著
The variation of tracheid morphological traits such as basic density and tracheid length, tracheid width and tracheid length-width ratio in the growth of Pinus densiflora plantation in different stands was studied. The results showed that the basic density and tracheid width of Pinus densiflora plantation in pure Pinus densiflora forest and mixed plantations of Pinus densiflora and Fraxinus mandshurica were significantly different. The basic density of Pinus densiflora plantation in pure Pinus tabulaeformis forest was higher than that in mixed plantations of Pinus densiflora and Fraxinus mandshurica, The tube width of Pinus densiflora in Pinus densiflora mixed forest was larger than that in pure Pinus densiflora plantation, while the tracheid length and tracheid length-width ratio of Pinus densiflora in Pinus densiflora and Pinus sylvestriformis mixed forest were not significantly different
