Abstract

In the last decades, a constant increase in the concentration of atmospheric carbon dioxide has been observed. In 2019, was observed the fourth highest carbon dioxide concentration and the largest amount of CO2 within sixty years of observation (NOAA, 2019). The last report of Intergovernmental Panel on Climate Change (IPCC) highlights that the landmark of 900 ppm could be reached in 2100, depending on the public policies and industry practices adopted worldwide. It is thus of general importance to study the plant responses stimulated by these atmospheric alterations, since those organisms directly depend on carbon dioxide as substrate for the photosynthesis process. The present proposal aims to assess and evaluate if the growth of Eucalyptus species is changed when challenged by increased concentration of CO2. For that, we intend to cultivate Eucalyptus plants in controlled conditions using distinct carbon dioxide concentrations. Several growth parameters will be evaluated to analyses the effect of the carbon dioxide enrichment and identify differences among the selected species.
