Abstract
In this paper the results of laboratory investigation on the range of wood decay caused by Heterobasidion annosum (Fr.) Bref. and Phellinus pini (Brot.) Bondartsev & Singer are described. Wood samples obtained from 25 different, both European and exotic tree species were used as the experimental substrate. The wood samples were exposed to mycelia of tested fungi for 30, 60 and 90 days, and subsequently the loss of their weight was assessed. The results showed arange of trophic preferences of H. annosum and P. pini. Better understanding of these processes could be useful in development of new methods for wood and forest protection against these extremely dangerous and com¬mon pests.
