Response of Norway spruce root system to elevated atmospheric CO2 concentration

Popis výsledku v původním jazyce

Root structure parameters, root biomass and allometric relationships between above- and belowground biomass were investigated in young Norway spruce stand (Picea abies /L./ Karst.) trees cultivated inside the glass domes with ambient (Ac, 375 ppm) and elevated (EC, AC + 375 ppm) atmospheric concentration of CO2. After 8 years of fumigation, a mean EC tree in comparison with AC one exhibited about 37 % higher belowground biomass. The growth of primary root structure was unafected by elevated CO2 concentration; however, the biomass of secondary roots growing on the primary root structure and the biomass of secondary roots growing in the zone between the soil surface and the first primary root ramification were significantly higher in EC comparing to AC treatment about 58 and 70 %, respectively. The finest root's (diameter up to 1mm) biomass as well as length and surface area of both primarz and secondary root structures showed the highest difference between the treatments; advancing EC t
