Dynamics of temperature normalized stem CO2 efflux in Norway Spruce stand

Popis výsledku v původním jazyce

Continuous measurements of stem CO2 efflux were carried out by an automated system during the growing season in 2006?2009. Further measured characteristics were stem temperature, stem increment and precipitations. Stem CO2 efflux was in tight relationship with changes in temperature with the mean coefficient of determination of 0.76. This infers that temperature was the main factor driving changes in CO2 efflux during the season. To eliminate effect of temperature and determine other factors influencingstem CO2 efflux, CO2 efflux was normalized for temperature of 10 °C (R10). Basic seasonal course of R10 followed the pattern of stem growth rate with its maxima in June and July. The other factor effect, which was possible to determine, was presence ofrainfall. Rainfall strong enough caused mostly increase in R10. This effect was the most significant when the R10 course had a decreasing trend in the second part of the growing season.
