Wounding the cambium of red maple ( Acer rubrum L.) altered peroxidase isoenzymes and enhanced the activities of peroxidase and indole‐3‐acetic acid oxidase in homogenates of adjacent cambial tissue. Four separate experiments were conducted, in May and July in each of two successive years. Wounds made in July caused greater increases in enzyme activity than those made in May. Alterations in peroxidase isoenzyme pattern were consistent for all experiments. These changes are intrepretable as aspects of the molecular regulation of barrier zone formation.
