The Influence of Leaf "Windows" on Crassulacean Acid Metabolism in the South African Succulent Senecio Rowleyanus (Asteraceae)

Net CO2 exchange rate (PN) of shoots and diel fluctuations in titratable acidity of leaves of Senecio rowleyanus were measured to determine whether penetration of radiant energy through leaf "windows" (narrow, translucent strips on the leaf epidermis) resulted in increased CAM. Nocturnal PN and nighttime increases in acidity were compared among plants with windows covered with reflective adhesive tape, transparent adhesive tape (to control for potential effects of the adhesive), and no tape. The windows did not significantly enhance the degree of CAM in S. rowleyanus.

Additional key words: CO2 gas exchange; chlorenchyma; water-storage parenchyma
