Ozone
flux in leaves at 60 days after emergence (DAE) showed a trend in decreasing order as
ACO2 + EO3 > ACO2 + AO3 > ECO2 + EO3 > ECO2 + AO3 > ACO2. Ozone
flux was found to correlate directly with
the plant’s photosynthetic performance and antioxidative response under different combinations of
ambient and elevated CO2 and O3
