Other claims from this paper (8)
- Intervention effect Elevated CO2 increased daily photosynthesis integral by about 25%.
- Intervention effect Elevated CO2 increased foliar carbohydrate content by about 58%.
- Intervention effect Early-season leaf nitrogen content was about 17% lower under elevated CO2.
- Observation Midseason ureide, total amino acid and nitrogen contents increased markedly.
- Intervention effect The elevated CO2 effect on leaf nitrogen content disappeared by midseason.
- Observation Individual amino acid levels supported that elevated CO2 plants overcame early nitrogen limitation.
- Intervention effect Elevated CO2 increased final dry mass by about 16%.
- Mechanism Authors propose increased nitrogen fixation as a possible explanation for acclimation to elevated CO2 nitrogen demand.
