Bud phenology and shoot elongation growth were monitored on Norway spruce (Picea abies [L.] Karst.) trees grown inside glass domes with adjustable windows for six years under ambient and elevated atmospheric CO2 concentrations CO2. Elevated CO2 slightly accelerated the consequential bud germinating phases and it significantly induced shoot elongation growth, espencially of sun-exposed shoots in a stand with sparse density. At the end of the growing seanson the total shoot length did not show any differences between the treatments.
