Title
Response of Photorespiration of Wheat Flag Leaf to Light Intensities and CO_2 Concentrations
Kang Hua-jin Mailei zuowu xuebao 2013
Other claims from this paper (10)
- Observation Wheat flag leaf saturating light intensity was 1 960.63μmol·m-2·s-1 at 21% O2.
- Observation Wheat flag leaf saturating light intensity was 2 030.12μmol·m-2·s-1 at 2%O2.
- Observation Apparent photorespiration increased with PAR from 50 to 800mol·m-2·s-1 and then stabilized.
- Observation Total photorespiration increased with PAR from 50 to 800mol·m-2·s-1 and then stabilized.
- Observation Apparent photorespiration first increased with CO2 and reached a maximum at 600μmol·mol-1.
- Observation Total photorespiration decreased as CO2 concentration increased.
- Observation Apparent and total photorespiration differed significantly below 380μmol·mol-1 CO2.
- Observation The ratio of total photorespiration to carboxylation rate decreased as CO2 increased.
- Observation The ratio of total photorespiration to carboxylation rate fluctuated little at different light intensities.
- Mechanism The authors inferred that suitably high light intensity and CO2 concentration improve carboxylation rate.
