Other claims from this paper (12)
- Intervention effect Elevated CO2 (FACE) stimulated the number of shoots per stool in poplar coppice.
- Intervention effect Elevated CO2 (FACE) stimulated leaf area index of poplar coppice, measured with a canopy analyzer.
- Intervention effect Elevated CO2 (FACE) stimulated annual leaf production of poplar coppice.
- Intervention effect Elevated CO2 (FACE) did not affect dominant shoot height of poplar coppice.
- Intervention effect Elevated CO2 (FACE) did not affect canopy productivity index of poplar coppice.
- Method / resource Leaf area index measured with a fish-eye canopy analyzer (LAIoptical) showed considerable differences from LAI estimates based on litter collections and allometric relationships in poplar.
- Intervention effect Elevated CO2 (FACE) increased biomass of poplar coppice.
- Intervention effect Elevated CO2 (FACE) initially stimulated absolute and relative growth rates of poplar, and the stimulation disappeared after the first growing season following coppicing.
- Mechanism The FACE-driven biomass increase is attributed to an initial stimulation of growth rates in poplar.
- Mechanism An ontogenetic decline in growth under FACE, with competition in the dense plantation, may have caused the decrease in biomass gain of poplar.
- Intervention effect Fertilization did not influence aboveground growth of poplar.
- Association Some FACE responses of poplar were more pronounced in fertilized trees.
