The Effect of Air Elevated [CO2] on Crown Architecture and Aboveground Biomass in Norway Spruce (Picea Abies (L.) Karst).
Original language description
Potential influence of air elevated [CO2] on aboveground biomass was investigated on young (17-19 year old) Norway spruce (Picea abies [L.] Karst.) trees cultivated inside glass domes (GD) with ambient (A, 370 mmol (CO2) mol-1) and elevated (E, 700 mmol(CO2) mol-1) atmospheric CO2 concentrations ([CO2]) established in 1997. GDs were working as a semi-open system (Urban et al. 2001). The trees were growing in two different stand densities (S, 5,000 tree ha-1 and D, 10,000 tree ha-1) until 2002. Then thefirst analysis of harvested trees from schematic thinning was done. Two years later the second analysis was performed. Amount of branches with secondary shoots (SS), total amount of SS on branches were higher within the crowns of E- trees comparing to A- ones, particularly in S stand. After thinning, number of branches with SS and stem SS decreased and it was found to be even lower in ES than in AS. However, leaf (LB), branch (BB), stem (SB) and total aboveground (TBA) biomass of tree w
