N2  - The Institute of Forest Genetics and Tree Breeding, Coimbatore, India has a long term systematic tree improvement programme for Eucalyptus species aimed at enhancing productivity and breeding for trait specific clones. In the process, thirty high yielding clones of Eucalyptus camaldulensis Dehnh. were identified. Carbondioxide enrichment studies in special chambers help in understanding the changes at individual level, and also at physiological, biochemical and genetic level. It also provides valuable information for establishing plantations at different geographic locations. Considerable variations were observed when the selected 30 clones of E. camaldulensis were subjected to physiological studies under elevated CO2 conditions (600 mol mol-1). Ten clones exhibited superior  growth coupled with favourable physiological characteristics including high photosynthetic rate, carboxylation and water use efficiency under elevated carbon di oxide levels. Clones with minimal variation in physiological characteristics under elevated levels of CO2 suggest their ability to overcome physiological stresses and adapt to varying climatic conditions.
