Abstract:Isoenzyme and SDS-PAGE techniques were used to analyze 11 cultivars of genusCymbidium. Among 24 bands of esterase and cytochrome oxidase, 23 were polymorphic,and 25 of 30 bands produced in SDS-PAGE were polymorphic. Based on the clusteranalysis of these markers, biochemical results were consistent with those of traditionaltaxonomic study, except that the systematic status for several Cymbidium cultivars weredifferent from the mophological classification.
