Peroxidase levels in the cotyledons of hazel seed (Corylus avellana)

Peroxidase activity was demonstrated in extracts from hazel cotyledons and the cytoplasmic enzyme was partially characterized. Levels of cytoplasmic and org@tnellar peroxidase were monitored in seeds stratified at 5” and incubated under moist conditions at 20°. Specific activities of the enzymes in both subcellular localizations remain constant throughout nine weeks stratification but show a steady rise in activity from seeds maintained at 20°.
