Pinus cembra is getting more and more popular every day, whereas in our region it is still not that well established. As the interest for the use of this wood is growing bigger, we decided to make a research about its resistance to fungal decay. The resistance is a characteristic of great value, because having all the characteristics but lacking suitable resistance, the wood cannot be used outdoors. For this purpose we exposed Pinus cembra wood to three different fungi. The test was made by sawing two boards into four groups of specimens. One group consisting of sapwood, another three of heartwood of different ages. After we had chosen five samples for extraction from each group, we divided the groups and aged half of them artificially, the other half remained unaged. Finally we exposed them to fungi. During all these procedures the mass of samples was determined in order to get the necessary data for the following research. After testing the data was analysed and we concluded that Pinus cembra, in spite of high share of extractives, possesses weak resistance to wood-decay fungi. Artificial aging of Pinus cembra does not affect significantly its resistance. According to the test results we classified the wood of Pinus cembra to the fourth resistance class, i.e. among less resistant wood species and it can be easily compared to spruce wood.
