Influence of Norway Spruce and European Larch Heartwood Ring-Width on Extractive Content and Durability

Norway spruce and European larch wood are among the most important species for construction applications in central Europe. In order to assess the influence of the ring-widths and presence of the extractives on the performance of these wood species against wood decays fungi, Soxlet extracted and non...

In order to assess the influence of the ring-widths and presence of the extractives on the performance of these wood species against wood decays fungi, Soxlet extracted and non-extracted spruce and larch wood specimens with different ring-widths were exposed to three brown rot fungi according to the EN 113 procedure.
