The possibility of improving the resistance of beech wood (Fagus moesiaca) to two dangerous wood decaying fungi: Trametes versicolor – white rot agent and Coniophora puteana –brown rot agent, was investigated under laboratory conditions. The heat treatment of 200º C/5 hours, vacuum impregnation with boric acid (5%) and the combination of the heat treatment and subsequent impregnation were used. Thermal modification of wood (TMW) and impregnation with boric acid (B) increase the resistance of wood to the investigated fungi.Weight loss of the samples impregnated with boric acid (B) was approximately the same for both tested fungi. Impregnation of thermally modified samples (TMW + B) increased the resistance to Trametes versicolor in comparison to the samples of wood that were only thermally treated (TMW), but the resistance of these samples was lower than the samples of wood impregnated with boric acid (B). Thermal modification + impregnation with boric acid (TMW + B) showed lower resistance to Coniophora puteana fungus than these treatments (TMW or B) separately.
