Response of 25-day old Eucalyptus globulus to elevated CO2

Increasing [CO2] may influence commercial crop and timber yield. While selection of genotypes sensitive to elevated [CO2] (e[CO2]) appears possible in agricultural crops, there is limited evidence for genotype-by-CO2 (G×CO2) interactions in commercial tree species. We examined [CO2] responsiveness in 124 open-pollinated Eucalyptus globulus subspecies globulus (E. globulus) families with the aim of assessing whether G×CO2 interactions are detectable in seedlings for early-age screening. Plants were grown in ambient (a[CO2]; ~405 μmol mol-1) and e[CO2]...
