CAM-cycling in Delosperma tradescantioides

Delosperma undergoes a change in its photosynthetic CO2-uptake when subjected to drought. A formerly clear C3-pathway of CO2 uptake shifts to CAM and CAM-cycling. The effects of a couple of environmental factors like photon flux density, drought and temperature on this transient from C3 to CAM have been studied by means of gas exchange, chlorophyllfluorescence and acid determination.
