An electrophoretical analysis of glutamate oxaloacetate transaminase, phosphogluco isomerase and peroxidase in Higo chrysanthemum provide information for cultivar identification. In all three enzymes of the twenty-nine cultivars used, degree of polymorphisms in isozymes are observed and each cultivar shows different zymogram. In some cultivars, zymograms exhibit the same number abd positions of bands but ahd different staining intensities.
