摘  要：
通过对贵州省贵阳市乌当区永乐乡、麻江县杏山镇两种立地的响叶杨Populusadenopoda林分中两种响叶杨类型生长量和材性分析表明,粉皮响叶杨平均高、材积比粗皮响叶杨分别大42 06%、41 61%。响叶杨纤维长、宽、长/宽、基本密度受环境、遗传因子影响的差异不显著,响叶杨纤维长度为0 933 0mm、宽度为0 198mm、长/宽为47 50、基本密度为0 437 1g·cm-3;在径向变异上差异不明显,各年轮与纤维长、宽、长/宽、基本密度的相关性表现(除粉皮响叶杨的各年轮与基本密度相关性极显著外)不显著;在纵向变异上除粉皮响叶杨基本密度的差异不显著外,其它差异都表现显著,而粗皮响叶杨在不同高度的纤维长、基本密度的差异极显著,纤维长、宽与高度呈负相关,基本密度与响叶杨高度呈正相关。

摘  要：
Through analysis on growth and timber characteristic in two different types Populus adenopoda forestry at Yongle and Majiang in Guizhou province,the result showed that pale husk Populus adenopoda Mazim were 42 06%,41 61% more than coarse husk Populus adenopoda respectively at average height and average wood volume. Populus (adenopoda’s) fibre length,fibre width,length-width ratio,basic density that were influenced by environmental factor and genetic factor showed indistinctive difference , fibre length is 0.9330mm,fibre width is 0.198mm,fibre length /fibre width is 47.50,basic density is 0.4371g·cm~(-3). They had indistinctive difference at radial variation. The relation of the annual rings and fibre length,fibre width,length-width ratio,basic density showed insignificant(except the relation of annual rings and basic density of pale husk Populus adenopoda).So was at transverse variation.However, besides the pale husk Populus adenopoda’s basic density showed indistinctive difference on tertical vertical variation, the others showed significant difference .The relation of the fibre length,the fibre width and the fibre height showed the negative correlation ,the relation of the basic density and the trees’s height showed the positive correlation.
