Differences in Wound Closure Rates in 12 Tree Species

Abstract

Purposefully inflicted wounds were observed on 12 species of trees commonly used in urban landscapes and along city streets. One group was observed in an urban environment in Nashville, Tenn., the other in a rural lawn environment in Wooster, Ohio. Wound closure in both environments was more closely correlated to species than to commonly used growth parameters. In both environments, Fraxinus pennsylvanica and Liquidambar styraciflua closed wounds more quickly than Pyrus calleryana ‘Bradford’, Gleditsia triacanthos var. inermis , and Betula nigra .
