- Intervention effect Elevated ozone decreased wheat grain yield by 26%.
- Intervention effect Elevated ozone decreased wheat grain weight by 18%.
- Intervention effect Elevated ozone decreased wheat grain number per ear by 11%.
- Intervention effect Elevated ozone decreased wheat ear number per plant by 5%.
- Intervention effect Elevated ozone decreased wheat harvest index by 11%.
- Intervention effect Elevated ozone decreased wheat light-saturated photosynthetic rate (Asat) by 40%.
- Intervention effect Elevated ozone decreased wheat stomatal conductance (Gs) by 31%.
- Intervention effect Elevated ozone decreased wheat chlorophyll content (Chl) by 46%.
- Observation Leaf physiological traits declined more than yield under elevated ozone.
- Observation Spring and winter wheat responded similarly to elevated ozone.
- Observation Asat, Gs and Chl decreased most strongly at grain filling.
- Intervention effect Elevated CO2 could significantly mitigate elevated ozone harm.
