Tracheid length, specific gravity, lodgepole pine


Significant tree-to-tree differences in both specific gravity and tracheid length were found in lodge-pole pine trees growing in the mountains of western Alberta. No geographic variations of the properties were observed, but within geographic growth zones, trees growing at lower elevations had longer tracheids. Within the stem, specific gravity decreased as height above ground increased. The relationship of age (rings from pith) and specific gravity was different at different sampling heights within stems. At all heights tracheid length increased with age.
