Abstract
Chlorophyllase activity and photosynthetic membrane proteins of two lots of Hedera helix were studied. Both the HV variety with variegated leaves and HC variety with green leaves were observed. Proteins from green, white and white-green portions of leaves differing in age were compared using dodecyl-sulfate-polyacrylamide gel electrophoresis. The white or white-green regions of Hedera helix var. aureomarginata (HV) did not differ significantly in chlorophyllase activity.
