Determination of the photosynthetic pathways of the plants in the studied areas would be very useful for evaluation of the modern vegetation and prediction of changes. Crassulacean acid metabolism (CAM) is a specialized mode of photosynthesis that features nocturnal CO2 uptake, facilitates increased water-use efficiency. A large variation in CAM has been found within the genus Sedum. C3 species, CAM constitutive species and CAM inducible species under water stress or salinity have been recognized. Diurnal acidity cycle in Sedium caucasicum species which is considered endemic in Caucases occurs similar to that of in CAM plants regardless if they are grown in a greenhouse or naturally. The obtained results confirm that Sedum caucasicum is an obligate CAM plant.
