Abstract

The decay resistance of durable heartwoods is primarily due to heartwood extractives, but some extractives have been found to be degradable by wood decaying fungi. We investigated the degradation of heartwood extractives in Siberian larch by the brown rot fungi Coniophora puteana and Rhodonia placenta and found that neither fungus caused the degradation of flavonoids, the primary organic solvent-soluble extractives in the larch samples. However, both fungi caused the gradual depletion of arabinogalactan, the polysaccharide extractive found in larch heartwood.

有机溶剂溶性萃取物和阿拉伯半乳聚糖在西伯利亚落叶松心材褐腐降解过程中的命运

耐用心材的抗腐性主要是由于心材提取物，但一些提取物已被发现可被木材腐烂真菌降解。研究了褐腐真菌Coniophora puteana和Rhodonia胎盘对西伯利亚落叶松心材提取物的降解作用，发现这两种真菌都不能降解落叶松样品中主要有机溶剂溶性提取物黄酮类化合物。然而，这两种真菌都导致了阿拉伯半乳聚糖的逐渐消耗，阿拉伯半乳聚糖是落叶松心材中发现的多糖提取物。

期刊介绍： European Journal of Wood and Wood Products reports on original research and new developments in the field of wood and wood products and their biological, chemical, physical as well as mechanical and technological properties, processes and uses. Subjects range from roundwood to wood based products, composite materials and structural applications, with related jointing techniques. Moreover, it deals with wood as a chemical raw material, source of energy as well as with inter-disciplinary aspects of environmental assessment and international markets. European Journal of Wood and Wood Products aims at promoting international scientific communication and transfer of new technologies from research into practice.
