Cieplne metody pomiaru przepływu wody w pędach roślin drzewiastych

Water flow in woody plant depends on many endogenous and environmental factors. Results of water flow measurements are frequently used in the research on physiology of woody plants and, ecophysiology to describe tree condition, water utilization and connected with these various theoretical and practical matters. Among the techniques of water flow measurements, the thermal methods are most widely used. It is because of easy installation of the system, possibility of continuous measurement with fast final results. The paper reviews various thermal methods of water flow measurements in woody plants with emphasis on the accuracy of measurements and potential sources of errors.
