    Description

    Ten 6-inch trees from each of 22 species were sampled. Differences in EMC occurred at 85 and 71 percent RH but not at 50 or 25 percent; there was essentially no difference between sapwood and corewood. Radial shrinkage varied from 4.1 percent in water oak to 8.0 percent in hickory, while tangential shrinkage varied from 7.9 percent in sweetbay to 12.2 percent in hickory. For volumetric shrinkage, 61 percent of the variation was accounted for by SG; the relationship was linear. The apparent fiber saturation point varied from 28.1 percent from green ash to 33.1 percent for white oak.
