Tension Wood Formation Following Release of Upland Oak Advance Reproduction
Keywords:Red oak, white oak, tension wood, advance reproduction
AbstractStem straightening and tension wood formation in advance red oak and white oak reproduction were studied. Saplings straightened either as a result of a lateral branch assuming dominance or by a reorientation of the leaning stem. Tension wood fibers were greater on the upper side than on the lower side of straightening stems. The greatest concentrations of tension wood fibers were in or above the stem region in which straightening took place. Tension wood fiber formation began immediately following release and continued at an increasing rate for the period studied. The ratio of upper increment width to lower increment width was greater in the zone of maximum straightening and several years after straightening had begun.
