RELATIONSHIP BETWEEN WOOD EXTRACTIVES AND WOOD DECAY

The durability of following five wood species: Zelkova carpinifolia, Ulmus glabra, Pterocarya fraxinifolia, Carpinus betulus and Acer laetum were studied. Wood blocks exposed to Trametes versicolor(a white rot fungus) under laboratory conditions according to DIN52176 standard. After 16 weeks incubat...
