The susceptibility of Scots pine heartwood from various Polish forestry regions to the brown rot fungus Coniophora puteana (Schumach.) P. Karst

This paper presents the results of tests of compression strength parallel to the grain, conducted on pine wood (Pinus sylvestris L.) samples from various Polish forestry regions, exposed to the Coniophora puteana fungus. According to the test results, the resistance of wood to the fungus varies only slightly depending on its place of origin. Exposure to the tested fungus caused a reduction of density and compression strength parallel to the grain. No correlation was found between this reduction and the place of origin of pine wood samples.
