Wounding, sapwood, heartwood, fire wounds


Heartwood formation was retarded by wounds on white oaks in Maine and Missouri. Maine samples with fire wounds had 22-23 rings of sapwood near the wound whereas control trees had 9. Missouri samples subjected to frill and herbicide treatments averaged 16-17 rings of sapwood near the wound, whereas control trees averaged 12. The effects of wounding on Missouri trees were pronounced at heights of 1, 2.5, and 6 m.
