Environmental factors influencing the relationship between stem CO2 efflux and sap flow

Original language description

Key message Beside temperature, soil moisture was found as the most important environmental factor influencing the relationship between stem CO2 efflux and sap flow. Abstract Stem CO2 efflux is an important component of the forest carbon balance. Even after several studies on this issue, there is still uncertainty about the influence of the sap flux on stem CO2 efflux. This study analyses stem CO2 efflux and sap flow measured on Norway spruce [Picea abies (L.) Karst] trees and environmental factors influencing this relationship during the growing seasons of 2010 and 2011. Stem CO2 efflux measurements were performed using an automatic dynamic closed gasometrical system, whilst sap flow measurements were carried out by applying a sap flow method heat pulse velocity. Stem CO2 efflux was positively correlated with stem temperature; sap flow was positively correlated with incident global radiation. During optimal soil moisture conditions, stem CO2 efflux and sap flow were positively correlated while during dry conditions, stem CO2 efflux and sap flow were not positively correlated. Almost all significant correlations between stem CO2 efflux and sap flow were not controlled by any investigated environmental factor.
