刺楸木材微纤丝角与组织比量的变异研究
0
()
摘要:
以安徽琅Ya山天然林内刺楸成年树木为材料,对其微纤丝角与组织比量的变异进行了分析,结果表明:(1)木纤维次生壁S2层微纤丝角自髓心向外逐渐减小,17年左右达最小值,然而又增加。

Study on the Variation of Microfibrillar Angie and TissueProportion in Pricky Coster Oil Tree(Kalopanax septemlobus)
()
Abstract:
The testing material was drawn from the mature trees grawn in naturalstands of Mount.Langya,Anhui Province,The wood variation of microfilrillar angle andtissue proportion were analyzed.The results show:1)microfibrillar angle within the S2 lay-er of the secondary wall in fibers decreases to minimum at 17-year from pith outward,thenincreases again near the bark of the tree;2)along the stem height,microfibrillar angle de-creases to minimum at 1.3m height,then increases again near top of the tree;3)the corre-lation coefficient between the fiber length and the microfibrillar angle is not significent (r= 0. 5206);4) the tissue proportion is different with anatomical elements:the fiber proper-tion decrease gradually,the vessel proportion and the ray proportion of the wood increasegradually from pith outward and along the stem height.
Key words:  Pricky coster-oil tree Microfibrillar angle Tissue proportion Wood Variation,
