The rate of radial moisture diffusion in desorption was determined for both the ray-tissue and the surrounding tissue of white oak, northern red oak, and cherrybark oak. In all these species, radial moisture diffusion was found faster in ray tissue than it was in the surrounding tissue. The relationship of this phenomenon to surface checking during drying is discussed.
