ABSTRACT
The object of the presented research project was sapwood of Scots pine (Pinus sylvestris L.), which was subjected to thermal and hydrothermal treatment. The objective of the performed investigations was to determine fungal resistance of this material to wood destroying fungi. Experimental wood was modified in the atmosphere of air and water vapour in conditions of the following temperatures: 160, 190 and 220°C for 6 and 24 hours. Fungal resistance of modified wood was determined applying an accelerated mycological test. The following test fungi were used in the performed experiment: Coniophora puteana, Gleophyllum trabeum, Poria placenta and Coriolus versicolor. The obtained results showed a correlation between conditions of the performed hydrothermal process of wood treatment and its resistance to test fungi species. Wood modified in the atmosphere of water vapour at the temperature of 220°C for 24 hours was characterised by the highest resistance against the s
