Inhibitory effects of leachates from Scots pine wood on germination of some wood rotting fungi
Leachates from sapwood of Pinus sylvestris inhibited or reduced the germination of basidiospores of the wood decay fungi tested. The fungi were selected among those preferentially colonizing hardwood or softwood, representatives for brown rot and white rot fungi, early basidiomycete colonizers and late basidiomycete colonizers in above-ground parts of pine as well as fungi found in high frequencies in window frames. In contrast, leachates from the heartwood were less inhibitory to germination of the majority of the tested fungi. Wood materials for the tests were selected to reveal differences in inhibitory effect of pine heartwood and sapwood according to:
1. Trees cut in the summer or in the winter
2. Latitude at which the trees had grown
3. Method of drying kiln-dried or air-seasoned wood
No differences in inhibitory effect against the test fungi in relation to these different wood materials were revealed.
