Knowledge of the wood durability and the factors that affect it is critical in determining its service life in specific applications and, consequently, enables its continued use. An important factor affecting the natural durability is the presence or absence of biologically active substances, i.e., extractives. . Unfortunately, most of them are water-soluble and therefore leached from wood when exposed to weathering. No information on the resistance of weathered wood to other wood-degrading fungi is currently available. There is also a lack of knowledge on the dynamics of extractive leaching and its influence on durability. In this study, the resistance of weathered sweet chestnut and European oak to Trametes versicolor and Rhodonia placenta was determined. Parallel samples were taken and their extractives content determined.
Keywords: sweet chestnut, European oak, durability, extractives
