最近引进的31 P核磁共振光谱法为同时直接评价高等植物细胞的细胞质和液泡pH值提供了一种新的方法（J.K. M. Roberts，P.M. Ray，N. Waderlardetzky和O. Sardetzky，1980，Nature 283，870-872; 1981，Planta 152，74-78）。使用这种方法，我们已经能够检测到当温度从4 ° C升高到28°C时，玉米根尖细胞质区室水平上的选择性pH降低约0.5个单位。这种效应是完全可逆的温度。在液泡区室的水平上没有检测到pH值的变化。
The recent introduction of 31P nuclear magnetic resonance spectroscopy offers a new approach to the problem of obtaining a simultaneous and direct evaluation of both the cytoplasmic and vacuolar pH in higher plant cells (J. K. M. Roberts, P.M. Ray, N. Waderlardetzky and O. Sardetzky, 1980, Nature 283, 870–872; 1981, Planta 152, 74–78). Using this method we have been able to detect a selective pH decrease of about 0.5 units at the level of the cytoplasmic compartment of maize root tips when the temperature was increased from 4 to 28°C. This effect was completely reversible with temperature. No pH variation could be detected at the level of the vacuolar compartment.
