Stomatal responses of Eucalyptus (Eucalyptus sp.) grown at different concentration of carbon dioxide (CO2) and temperature, Western Sydney, Australia

• Conclusions •Even with leaves in all treatments exhibited stomatal closure responses to increased [CO2], this response was significantly reduced in leaves growing in Ce treatments, showing that stomata of E. globulus do acclimate to growth in [CO2]. • The stomatal CO2 response of plants grown in Te did not differ from that in plants grown in Ta. • Te and/or Ce treatments did not have any effect on stomatal density/size or KL. • This study indicates that while stomatal CO2 responses has the potential to cause water savings under Ce, this potential is reduced by stomatal acclimation to prevailing growth [CO2] and is likely not present during conditions when gs is constrained by plant hydraulics.
