Activity of peroxidase, cqtalase, and IAA-oxidase in flower buds, stems and stem callus cultures derived from four pure genetic lines of Cucumis sativus L., i.e. male, monoecious, female and hermaphrodite was determined. The activities of all enzymes in flower buds and callus cultures are considerably higher in the female lines then in male ones. IAA-oxidase activity is the highest in female line, independently of the type of plant material under examination. The activities of the remaining two enzymes depend on the type of tissue or organ under examination
