Abstract
The study summarizes the results of the influence of outer temperature gradient on the accuracy of sap flow rate measurements in tree trunks by means of thermic-based methods. Particularly it deals with those methods based on the continual accurate measurements of temperature differences between the heated part and the part with natural temperature, at the measuring point. The battery of thermometers significantly compensating the mentioned temperature gradient effect is described.Keywords
