摘要：

Over two seasons in c. 600 ppm CO2, oak had lower stomatal conductance in CO2-enriched compared to ambient air, Beech showed no response to CO2 concentration on sunny days, Mirroring this pattern, exposure to elevated CO2 reduced whole-shoot hydraulic conductance per unit leaf area in oak, but not in beech.
