Abstract:

This paper discusses about the biochemical and morphological changes in Eucalyptus sp clones to elevated CO2 conditions in AOTC (Automated Open Top Chambers). In this study, three months old clones of Eucalyptus sp were exposed to elevated CO2 levels in open top chambers at 900 ppm and 600 ppm for a period of four months. In Eucalyptus sp clones, the highest values of chlorophyll was recorded by the clone I (39.48) and the lowest values of chlorophyll (26.70) is recorded in clone V in ambient conditions for Eucalyptus sp after four months. The clonal mean was high (36.73) in clone I and treatment mean was high (38.33) in chamber control. The shoot fresh weight was high in clone III (29.32g) in ambient conditions and the lower shoot fresh weight was reported in clone IV (9.07g) in chamber control. Clonal mean was high in clone III (27.31 g) and treatment mean was high (18.52 g) in ambient conditions. Leaf fresh weight was registered high in clone III (33.42 g) in 900 ppm elevated CO2 levels and the lower leaf fresh weight was reported in the clone IV (15.02 g) in chamber control. Root fresh weight was high in clone II (13 g) under 900 ppm elevated CO2 and the lower root fresh weight was recorded by the clone I (5.04g). The clonal mean was high in clone IV (9.17g) and the treatment mean was high in ambient conditions (8.92g). This study concludes that there is an intra- specific variation in Eucalyptus sp, which can be utilized for future breeding programmes to develop genotypes that withstand the changing climatic conditions.
