e0“Leaf extension was stimulated following exposure of three interamerican hybrid poplar clones ( Populus trichocarpa P. deltoides ); ‘Unal’, ‘Boelare’, and ‘Beaupre’ and a euramerican clone ‘Primo’ ( Populus nigra × P. deltoides ) to elevated CO 2 , in controlled environment chambers.”

Other claims from this paper (13)
- Mechanism In three interamerican clones, increased cell expansion was associated with enhanced cell wall extensibility under elevated CO2.
- Intervention effect Elevated CO2 significantly increased cell wall elasticity in Boelare.
- Intervention effect Spatial analysis confirmed elevated CO2 stimulated wall extensibility across expanding Boelare leaves.
- Intervention effect Elevated CO2 lowered leaf cell water potential Ψ in Unal and Beaupre.
- Intervention effect Elevated CO2 lowered turgor pressure ( P ) in Unal and Beaupre.
- Intervention effect Primo showed no significant cell-wall property response to elevated CO2.
- Intervention effect Primo showed no significant leaf water-relations response to elevated CO2.
- Intervention effect Elevated CO2 significantly increased cumulative leaf length in Boelare.
- Intervention effect Elevated CO2 did not significantly increase leaf number in any interamerican clone.
- Mechanism The authors hypothesized that elevated CO2 stimulated final leaf size in the interamerican clones.
- Intervention effect Primo cumulative leaf length was not significantly affected by CO2.
- Intervention effect Measurements suggested elevated CO2 stimulated total leaf area across poplar hybrids.
- Mechanism The authors projected increased leaf area would enhance stemwood production in hybrid poplar coppice.
