- Intervention effect Elevated ozone reduced rice root growth more than shoot growth.
- Intervention effect Ozone decreased rice grain number per plant with fewer ears and grains per ear and more unfilled grains.
- Intervention effect 1000 grain dry weight did not change significantly under 50 or 100 nl/L ozone.
- Intervention effect harvest index (HI) did not change significantly under 50 or 100 nl/L ozone.
- Intervention effect 1000 grain dry weight declined 17.0% under 200 nl/L ozone.
- Intervention effect harvest index (HI) declined 4.8% under 200 nl/L ozone.
- Intervention effect CF50 reduced grain yield by 8.2% versus CFA.
- Intervention effect CF100 reduced grain yield by 26.1% versus CFA.
- Intervention effect CF200 reduced grain yield by 49.1% versus CFA.
- Intervention effect CF50 reduced biomass by 14.2%.

- Association 7 h-daily mean O3 concentration exposure was well correlated with relative grain yield.
- Association AOT40 was well correlated with relative grain yield.
- Observation A 10% yield loss was estimated at 46.9 nl/L O3.
- Observation A 10% yield loss was estimated at 12930 nl/(L.h) O3.
