Other claims from this paper (8)
- Intervention effect Photosynthesis of Encelia farinosa decreased during the day under doubled CO2 relative to the current CO2 concentration.
- Observation Photosynthesis of Encelia farinosa remained unchanged under the current CO2 concentration.
- Intervention effect Doubled CO2 enhanced photosynthesis of Encelia farinosa by 46% in the early morning relative to the current CO2 concentration.
- Intervention effect Doubled CO2 enhanced photosynthesis of Encelia farinosa by 26% at midday relative to the current CO2 concentration.
- Intervention effect Doubled CO2 enhanced photosynthesis of Encelia farinosa by 15% in the late afternoon relative to the current CO2 concentration.
- Intervention effect Sucrose and starch contents of Encelia farinosa increased during the day more under doubled CO2 than under the current CO2 concentration.
- Intervention effect Peak 14CO2 activity in sink leaves of Encelia farinosa occurred 3 h after labeling under doubled CO2 but at 5 h under the current CO2 concentration.
- Mechanism Faster photosynthate movement from source to sink leaves under doubled CO2 may explain the sustained enhancement of photosynthesis in Encelia farinosa.
