摘  要:
通过对兰考泡桐全树根材、枝材和千材解剖构造和密度的比较研究,结果表明:全树木材基本密度和木纤维比量为枝材>干材>根材;木纤维长度、宽度、腔径,导管长度和早、晚材管孔直径,木射线高度和宽度大小顺序为根材>干材>枝材。全树木材解剖构造和密度等15个因子多元方差分析和单因素方差分析表明,三者之间总体上差异极显著。

摘  要:
The comparative research results show that among rootwood,branchwood and stemwood,basic density and fibre proportion are branchwood>stemwood> rootwood,but length,width and cell diatmeter of fibre,vessel element length, diameter of vessel of earlywood and latewood,width and height of wood ray, longitudinal parechyma proportion are rootwood>stemwood>branchwood. Multivariate analysis of variance and one-factor analysis of variance upon basic density and other 15 parameters of wood anatomical structures and porperties among rootwood,branchwood and stemwood show that the difference among the three parts are very significant.
