Other claims from this paper (11)
- Intervention effect Defoliation did not significantly affect final sugar maple seedling biomass.
- Intervention effect Defoliation did not significantly affect final trembling aspen seedling biomass.
- Association Aspen growth recovery after defoliation was associated with slightly enhanced mean photosynthesis.
- Intervention effect Elevated CO2 did not significantly affect aspen growth.
- Intervention effect Elevated CO2 stimulated maple growth significantly only at mid-season.
- Mechanism Reduced photosynthetic capacity constrained simulated whole-tree photosynthetic responses to elevated CO2 in maple.
- Mechanism Reduced specific leaf area partly offset simulated whole-tree photosynthetic responses to elevated CO2 in aspen.
- Mechanism Reduced biomass allocation to foliage partly offset simulated whole-tree photosynthetic responses to elevated CO2 in aspen.
- Association Only a few measured traits showed a significant CO2-by-defoliation interaction.
- Observation The data do not support substantial alteration of tree responses to folivory by CO2 enrichment.
- Observation Regeneration-stage growth rates of some temperate trees may respond only moderately to near-doubled atmospheric CO2.
