Other claims from this paper (8)
- Intervention effect In rice, stomatal conductance decreased within a few minutes of once-per-minute pulses of high CO₂.
- Intervention effect In wheat, stomatal conductance was 20-35% lower for at least 30 min after the CO₂ pulses ended.
- Intervention effect In rice, stomatal conductance was 20-35% lower for at least 30 min after the CO₂ pulses ended.
- Observation In wheat, photosynthesis after the CO₂ pulses had stopped was below the values expected for the observed substomatal CO₂ concentration.
- Observation In rice, photosynthesis after the CO₂ pulses had stopped was below the values expected for the observed substomatal CO₂ concentration.
- Intervention effect In wheat, a single 2 s CO₂ pulse decreased stomatal conductance.
- Intervention effect In rice, a single 2 s CO₂ pulse decreased stomatal conductance.
- Association Plants in many CO₂ enrichment systems probably have lower photosynthesis and stomatal conductance than plants at the same mean CO₂ without pulses of higher concentration.
