Other claims from this paper (12)
- Intervention effect High CO2 increased dry matter, leaf area and tillering relatively more under saline conditions in both cultivars.
- Intervention effect Salinity greatly reduced wheat tillering.
- Intervention effect High CO2 partly reversed salinity suppression of tillering.
- Intervention effect High CO2 increased Modoc dry matter accumulation by 104% under salt treatment.
- Intervention effect High CO2 increased Matong dry matter accumulation by 73% under salt treatment.
- Intervention effect Salinity greatly reduced transpiration rates in both cultivars.
- Mechanism High CO2 caused increased leaf areas that compensated for lower transpiration per leaf area.
- Intervention effect Total transpiration was little affected by CO2 level within each treatment.
- Observation Matong showed greater stomatal closure than Modoc under salinity.
- Observation Matong had higher transpiration efficiency than Modoc under salinity.
- Intervention effect High CO2 did not significantly change sodium accumulation per dry weight.
- Mechanism Authors inferred that high CO2 stimulated tiller bud development and thus growth.
