Other claims from this paper (11)
- Intervention effect Elevated CO2 increased dry-condition photosystem II quantum yield throughout the day.
- Intervention effect Elevated CO2 increased dry-condition photochemical quenching coefficient.
- Intervention effect Elevated CO2 increased dry-condition transfer efficiency to open PSII centers.
- Intervention effect In wet plants, FACE enhanced photosystem II yield only at midday.
- Mechanism In wet plants, the midday yield enhancement was entirely attributed to changes in Fv′/Fm′.
- Observation Under dry ambient-CO2 field conditions, declining PSII quantum yield corresponded to rising NPQ.
- Observation Under dry ambient-CO2 field conditions, NPQ increased.
- Observation Dry ambient-CO2 conditions had no reported effect on xanthophyll de-epoxidation state.
- Intervention effect The authors conclude elevated CO2 enhances photochemical energy use during drought or midday.
- Mechanism The authors conclude NPQ protects against photoinhibition and photodamage.
- Intervention effect Elevated CO2 and water stress affected NPQ and the xanthophyll cycle differently.
