Abstract

The accurate assessment of actual tree stem respiration and its relation with temperature plays a considerable role in investigating the forest carbon cycle. An increasing number of research reports have indicated that tree stem respiration determined with the commonly-applied chamber gas exchange measuring system does not follow expectations regarding temperature relationships. This method is based on the nowadays widely-accepted theory that the respired CO2 in a tree stem would all diffuse outward into the atmosphere. However, it neglects partial CO2 that is dissolved in the xylem sap and is carried away by the transpirational stream. Scientists have started to realize that the respired CO2 measured with the chamber gas exchange method is only a portion of the total stem respiration (CO2 efflux), while the other portion, which is sometimes very substantial in quantity (thought to occupy maybe 15%-75% of the total stem respiration), is transported to the upper part of the stem and to the canopy by sap flow. This suggests that the CO2 produced by respiration is re-allocated within the stem. Accordingly, the change in CO2 efflux could be reflected in the rates of sap flow in addition to its dependence on temperature. Proper methods and instruments are required to quantify the internal and external CO2 fluxes in the trunk and their interaction with related environmental factors.
