Dormant bud tissue from two or more trees representing 18 red maple (Acer rubrum L.) cultivars was subjected to isozyme analyses using starch-gel electrophoresis. Polymorphic enzymes resolved were alcohol dehydrogenase, peroxidase, phosphoglucase isomerase, glutamate oxaloacetate transaminase, leucine aminopeptidase, acid phosphatase, and malic dehydrogenase. An enzyme pattern or combination of patterns was useful in identifying individual cultivars, these included: `Autumn Blaze', `Autumn Flame', `Bowhall', `Celebration', `Columnare', `Curtis', `Doric', `Firedance', `Gerling', Y.J. Drake', `Morgan', `Northwood', `Scarlet Sentinel', `Schlesingeri', and `Tilford'. `Armstrong', `October Glory', and `Red Sunset' could not be distinguished from each other on the basis of enzymes examined in this study.
