Abstract

Mountain pine beetle infested lodgepole pine (Pinus contorta var. latifolia) containing blue stain was used for the determination of permeability and diffusion coefficients. The results were then compared with the permeability and diffusion coefficients of noninfested wood that was free from the blue stain. The comparisons indicated that the blue stain in wood significantly increased the permeability of lodgepole pine, in both tangential and radial directions. Diffusion coefficients for blue-stained sapwood were greater than those observed for nonstained sapwood.
