尾巨桉树轮异常结构的解剖学分析
|
摘要
为了解尾巨桉木材环裂形成原因,通过对木材结构解剖分析,气候数据补充验证,判定尾巨桉木质部环裂与形成层受霜冻伤害产生应激反应及形成异常结构有关.异常结构为霜冻轮,纤维细胞未完全木质化,薄壁细胞量多.霜冻轮的存在对木材的强度、抗虫性和耐腐性产生一定的负面影响.
Anatomical analysis was made of the xylem of Eucalyptus urophylla to study the cause for the formation of cracked tree rings, and a supplementary verification was made using the climatic data. The results showed that the formation of xylem ring cracking was related to frost damage. When E. urophylla suffered frost damage, a stress reaction occurred at the cambium, resulting in the formation of an abnormal structure. The unusual structure was frost ring, which had more parenchyma cells and the fiber cells were not fully lignified. The existence of the frost ring had a negative effect on wood strength, insect resistance and corrosion resistance of the timber.
