Other claims from this paper (12)
- Intervention effect Ozone significantly reduced light-saturated CO2 uptake in wheat.
- Intervention effect Ozone exposure decreased stomatal conductance.
- Intervention effect Stomatal limitation increased significantly only during the first eight hours at 400 nanomoles per mole ozone.
- Intervention effect Other ozone treatments did not significantly increase stomatal limitation.
- Mechanism Reduced carboxylation efficiency was inferred as the predominant cause of lower light-saturated uptake.
- Intervention effect Carboxylation efficiency reached 58% of control after 16 hours at 200 nanomoles per mole ozone.
- Intervention effect Carboxylation efficiency reached 21% of control after 16 hours at 400 nanomoles per mole ozone.
- Intervention effect At saturating CO2, ozone inhibited photosynthesis by at most 22% after 16 hours.
- Intervention effect Ozone had a less pronounced effect on light-limited photosynthesis.
- Intervention effect Maximum quantum yield of CO2 uptake showed no significant decline after 16 hours at 200 nanomoles per mole ozone.
- Intervention effect At 400 nanomoles per mole ozone, quantum yields required eight hours before significant reduction.
- Mechanism Photochemical measures indicated photochemistry did not cause initial CO2 uptake inhibition.
