Abstract
Most of the peroxidase activity of strawberry petiole is obtained from ionic treatment and pectinase-cullulase digestion of the cell-walls: two ionically—and three covalently— bound isoperoxidases were separated by starch gel electrophoresis. A technique is described for preparing an active IAA-oxidase extract. Final oxidation products of indoleacetic and indoleacrylic aeids appear to be the most effective IAA-oxidase promoters. Aktivní peroxidázy z řapíků jahodníku byly získány po působení ionty a digescí buněěných stěn pektinázou a celuiázou. Pomocí elektroforézy na škrobovém gelu byly odděleny dvě iontově a tři kovalentně vázané isoperoxidázy. Je popsána metoda přípravy extraktu s aktivní oxidázou kyseliny indolyloctové. Zdá se, že koneěné produkty oxidace kyseliny indolyloctové a indolylakrylové jsou nejúčinnějšími aktivátory oxidázy kyseliny indolyloctové.Keywords
