A macroscopic and microscopic study of compartmentalization and wound closure after mechanical wounding of black walnut trees


, : A macroscopic and microscopic study of compartmentalization and wound closure after mechanical wounding of black walnut trees. Wood and Fiber 13(4): 275-291

Uniform mechanical wounds were made in 50 black walnut trees. Each tree was wounded at two different heights, 0.5 and 1.4 m, and at two different times, autumn (November 1975) and spring (March 1976). The 8 trees with one or more open wounds after one complete growing season were among the smallest and slowest growing trees. This suggests a positive relationship between growth rate and wound closure, but statistically the relationship was not significant.
