Abstract
Elevated [CO2] affects physiological, anatomical and morphological properties of plants, both directly and indirectly.
Higher carbon gain corresponds with higher transpiration demands.
Juvenile trees of Picea abies and Fagus sylvatica were planted under ambient (385 μmol [CO2] mol-1) and elevated (700 μmol [CO2] mol-1) concentration in semi-opened glass domes with adjustable windows.
We have evaluated biomass allocation and transpiration of the studied species.
No effect of elevated [CO2] on Norway spruce was observed.
European beech showed remarkable increase of root biomass and transpiration in elevated [CO2]. Reduction of the transpiration caused by the elevated [CO2] was not observed.
