31P nuclear magnetic resonance has been used to study the vacuolar and cytoplasmic pH of Acer pseudoplatanus, Catharanthus roseus, and Glycine max cells grown as cell suspensions. The adaptation of this technique to plant cells grown in liquid medium is described with emphasis on the removal of Mn2+ and phosphate from the extracellular medium and on providing the O2 supply of the cells in the nuclear magnetic resonance tube and the various problems of calibration. Aerobic and anaerobic cells show large differences in their glucose-6-phosphate, their cytoplasmic inorganic phosphate pools, and their cytoplasmic pH. Differences in the relative sizes of the cytoplasmic and vacuolar inorganic phosphate pools have been observed for the three cell strains studied.
