Dilute sulfuric acid solutions of pH 3.0, 4.0, and 5.8 were dripped into the wounds for 1 hr once a week for 7 weeks. In mid-August the trees were harvested, sectioned, and the amount of discolored wood associated with each wound was measured with a planimeter. Increased acidity did not affect the amount of discoloration that occurred.
