摘要

对不同木材性能之间的相互关系进行了检验,以确定千斤顶木材的整体质量和性能的一个性状对另一个性状的依赖性,注意到a*值与灰分含量呈高度显著正相关;绿比重体积收缩率;切向收缩伴径向收缩;全纤维素含量与半纤维素含量。L*值与a*值呈显著负相关;绿色比重与NaOH可溶性萃取物含量。体积收缩与切向收缩和径向收缩呈极显著正相关;切向收缩伴径向收缩;烘箱干燥比重与容器面积和射线宽度有关。L*值与a*值呈显著负相关,切向收缩与纤维直径呈显著负相关。除L*值与a*值、切向收缩率与纤维直径呈显著负相关外,与木材物理机械参数相关的参数均呈显著正相关。回归研究还表明,物理、化学、解剖和机械性能之间存在相当大的关系。

Correlation and regression studies on wood properties of jack (Artocarpus heterophyllus Lam.) for effective timber utilization
The interrelationships between different wood properties were carried out to check the dependence of one character over the other which defines the overall quality and performance of the jack wood Highly significant and positive correlation was noticed for a*value with ash content; volumetric shrinkage with green specific gravity; tangential shrinkage with radial shrinkage; holocellulose content with hemicellulose content. The negative and significant correlation has been recorded for L*value with a*value; green specific gravity with NaOH soluble extractives content. Highly significant and positive correlation was noticed for volumetric shrinkage with tangential shrinkage and radial shrinkage; tangential shrinkage with radial shrinkage; oven dry specific gravity with vessel area and ray width. The negative and significant correlation has been recorded for L*value with a*value, tangential shrinkage with fibre diameter. Highly significant and positive correlation was noticed for parameters related to physical and mechanical wood parameters except for The negative and significant correlation has been recorded for L*value with a*value, tangential shrinkage with fibre diameter. Regression studies also showed considerable relationships between the physical, chemical, anatomical and mechanical properties.
