Thesis analyse long-term effect of elevated CO2 on biomass of Norway spruce, depending on type of mixture (individual, group, monoculture) with European beech. Planting was realized to 2 glass domes (GD) on locality Biely Kríž in Moravian-Silesian Beskids. In first GD, concentration of CO2 was ambient (AC, ± 350 ppm) and in second GD elevated (EC, ± 700 ppm). After 8 years of cultivation, monoculture of Norway spruce achieved biggest average total biomass in conditions of EC and AC. However only single mixture had bigger average total biomass in conditions of EC compared to AC. In the group mixture and monoculture, average total biomass even insignificant decreased. This phenomenon called down-regulation of photosynthesis probably happened due to low nitrogen supply. Single mixture of spruce, with specie which has different architecture of root system could be appropriate adaptation measure on acidic stands.
