The techniques for measuring Hevea laticiferous turgor pressure which have been reported are summarized. The commonly used three methods used for measuring Hevea laticiferous turgor pressure have their limitation in deep and systematic observation of the variation of Hevea laticiferous turgor pressure and are not involved in the study of the variation of laticiferous turgor pressure under the normal ethrel stimulated tapping system. A possibility of using an improved cell pressure probe method which has been recently established for other plants is discussed in accurate measurement of the real time variation of Hevea laticiferous turgor pressure.
