Abstract
Gazania splendens is an ornamental and decorative plant which is cultivated in parks and gardens and shows distinct juvenile and adult leaves in transition from the vegetative phase to the reproductive phase. There is no information in current literature that Gazania shows heterophylly. The objective of the present study was to assess the physiological parameters such as the changes of peroxidase activity (POD), anthocyanin and chlorophyll content in juvenile and adult leaves. It was found that POD activity and chlorophyll level increased in the juvenile leaves compared to the adult ones in which anthocyanin content decreased. These results indicate that there is an inverse correlation between the amount of anthocyanin and chlorophyll in the juvenile and adult leaf tissues, and increasing POD activity may limit anthocyanin content in the adult leaves.
