摘要

这项工作的目的是评估木材的化学成分及其结晶度是否有助于分析存放在堆场中的亚马逊木材物种原木的真菌和昆虫降解情况。在这项研究中，使用了在露天堆场存放六个月的五种商业木材。对真菌和昆虫的降解程度、原木的含水量、总萃取物含量、木质素、全纤维素和结晶度进行了评估。得出的结论是，原木在堆垛中的位置与贮存时间有关，会影响所评估的特性。研究还发现，X 射线衍射法有可能用于分析储存在堆场中的亚马逊树种原木在真菌和昆虫作用下的降解情况。

Crystallinity and chemical structure of Amazon wood species in a log yard after natural degradation

The objective of this work was to evaluate whether the chemical composition of wood and its crystallinity can help in the analysis of degradation by fungi and insects in logs of Amazonian wood species stored in a stockyard. For this study, wood from five commercial species that had been stored in an open yard for six months was used. The scale of degradation by fungi and insects, the moisture content of the logs, the total extractive content, lignin, holocellulose and the crystallinity were evaluated. It was concluded that the position of the logs in the stacks, associated with the storage time, influenced the evaluated characteristics. It was also observed that X-ray diffraction has potential for analysis of the degradation by fungi and insects in logs of Amazonian species stored in the stockyard.

期刊介绍： The purpose of BioResources is to promote scientific discourse and to foster scientific developments related to sustainable manufacture involving lignocellulosic or woody biomass resources, including wood and agricultural residues. BioResources will focus on advances in science and technology. Emphasis will be placed on bioproducts, bioenergy, papermaking technology, wood products, new manufacturing materials, composite structures, and chemicals derived from lignocellulosic biomass.
