Seasonal Variation in CO2 Efflux of Stems and Branches of Norway Spruce Trees
Original language description
Stem and branch respiration were measured on Norway spruce (Picea abies) from May to October in four years. CO2 efflux was measured, using an IRGA and a closed gas exchange system. Measurements of ecosystem CO2 fluxes were done using the eddy covariance system. The temperature of woody tissue explained up to 68 % of their CO2 efflux. The mean annual Q10 ranged from 2•20 to 2•32 for stems and from 2•03 to 2•25 for branches. The mean annual normalized respiration rate, R10, for stems and branches ranged from 1•71 to 2•12 µmol CO2 m–2s –1 and from 0•24 to 0•31 µmol CO2 m–2 s–1, respectively. The annual contribution of stem and branch CO2 efflux to total ecosystem respiration were, respectively, 8•9 and 8•1 % in 1999, 9•2 and 9•2 % in 2000, 7•6 and 8•6 % in 2001, and 8•6 and 7•9 % in 2002. Standard deviation for both components ranged from 3 to 8 % of the mean. Stem and branch CO2 efflux varied diurnally and seasonally, and were related to temperature of the woody tissue and to growth
