Branch CO(2) efflux in vertical profile of Norway spruce tree

Popis výsledku v původním jazyce

Branch CO2 efflux of Norway spruce tree was measured in ten branches at five whorls during the growing season 2004 in campaigns of 3?4 times per month at the Beskydy Mts., the Czech Republic. Branch woody-tissue temperature was measured continuously in 10-min intervals for each sample position during the whole experiment period. Q10 and normalized CO2 efflux rate (E10?CO2 efflux rate at 10°C) was calculated for each sampled position. Estimated Q10 ranged from 2.12 to 2.89, and E10 ranged from 0.41 to 1.19 ?molCO2m2s1. East-side branches had higher efflux rate than west-side branches. The highest CO2 efflux rate values were measured in August and the lowest in October, which corresponds with woody-tissue temperature and growth processes during these periods. CO2 efflux was significantly and positively correlated with branch position within canopy and temperature. Branches from the upper whorls showed higher CO2 efflux activity and seasonal dynamics than branches from the lower whorls.
