Detailed analyses were made of wood samples taken from five black walnut trees grown in southern Illinois. Specific gravity varied with height and distance from the pith. Tangential shrinkage was greater than radial shrinkage and was negatively correlated with the number of vessels. As growth rate increased, specific gravity increased, fiber area increased, vessel lumen size decreased, and number of vessels decreased. Forest Sci. 16:95-100.
