Wood properties of immature ponderosa pine after thinning

Abstract

Trees from growing stock levels of 20, 60, and 100 in sapling and pole stands were sampled at three vertical positions -zero, 25, and 50 percent of total height above the 1-foot stump. Wood grown during the 10-year period after initial thinning was compared for growth and wood properties. Wide differences in radial growth, induced by thinning treatments, were not accompanied by significant differences in specific gravity, latewood percentage, tracheid length, nor microfibril angle. However, all properties except microfibril angle were significantly affected by vertical position on the stem.
