Other claims from this paper (11)
- Observation CO2 enrichment significantly increased shoot and total biomass only at moderate to high N.
- Observation CO2 enrichment did not significantly enhance biomass under droughted or well-watered treatments.
- Observation Elevated CO2 did not relieve drought and nitrogen stress effects on dry matter accumulation.
- Observation Enriched CO2 significantly reduced shoot N content.
- Observation Enriched CO2 significantly reduced shoot and total N uptake.
- Observation Enriched CO2 slightly decreased root N content and uptake.
- Observation Shoot critical N concentrations were lower under 700 than 350 µmol mol−1 CO2, in both moisture treatments.
- Observation Under enriched CO2, critical N concentration was 2.1% in droughted plants.
- Observation At ambient CO2, critical N concentration was 1.9% in well-watered plants.
- Observation At ambient CO2, critical N concentration was 2.6% in droughted plants.
- Observation CO2 enrichment increased water use efficiency and nitrogen use efficiency.
