Abstract:

Water potential measurement in plant tissue with Chardakov method is one of the basic experiments in the plant physiology. In this study, we optimized the concentration of methylene blue, material selection, sampling method, and experimental equipments, and established a system of convenient operation and good repeatability, which could be used for experiment teaching and research.

Key words: water potential; Chardakov method; method optimization
