e0“The decrease in leaf physiological characters was much greater than that in yield when wheat was expose to elevated [O3], while light-saturated photosynthetic rate (Asat), stomatal conductance (Gs) and chlorophyll content (Chl) decreased by 40%, 31%, and 46%, respectively.”

- Association Most studied variables declined linearly as ozone increased.
- Observation Asat, Gs and Chl decreased most strongly at grain filling.
- Intervention effect Elevated CO2 could significantly mitigate elevated ozone harm.
