Title: A Critical Evaluation of Tissue-Immersion Methods for Measurement of Plant Water Potential
Creators: O'Leary, James W.

Abstract: Plant water potential was measured simultaneously by the change-in-length method and the Schardakow-dye method on segments of potato tubers. In over half of the tests, the change-in-length method underestimated the true water potential, interpreted to be the result of several sources of error inherent in the method. Therefore, the dye method is strongly recommended as the only tissue-immersion method suitable for field measurement of plant water potential.
