Durability of the sapwood and heartwood of blue beech (Carpinus betulus) against white rot fungus (Coriolus versicolor) was studied. As treatment three concentrations of preservative (control or 0%, 3%, and 5% of ACC) were applied. The measuring 1.5x2.5x5cm3 as dimension of wood samples (sap and heartwood) was used. During 16 weeks exposure, untreated wood blocks were completely deteriorated by the fungus and their weight losses were 24.4% in sapwood and 23.4% in heartwood. However, 3% and 5% of ACC caused that weight losses were significantly decreased. In 3% of preservative sapwood decreased only 1.08%, and heartwood reduced 0.94%. In 5% of ACC weight losses were 0.97% (sapwood) and 1.03% (heartwood). Thus there was a significant difference between treated and untreated wood, and no significant differences were occurred between sapwood and heartwood when exposed to the white rot fungus.
