A new technique for the in-situ measurement of the transpiration from a tree was proposed in this paper. This technique is composed of the following two points:(a) application of two-sensor type evaporation meter to the transpiration measurement from leaves of tree (b) estimation of total transpiration from a tree. Transpiration from some kind of trees such as mango, rubber and mulberry could be successfully measured. Total transpiration from a mango tree was also well estimated by the technique. It was concluded that the technique can be widely used not only in Japan but also in South East Asian countries.
