Bioelectric potential is generated by ions in a plant cell; the potential changes with physiological activities of the plant. Therefore, measurement of the potential is a promising method for evaluation of plant activities. In this study, we investigated the mechanism of potential response generation due to photosynthetic reactions of plants. For this purpose, we measured the bioelectric potential with air replaced by N 2 gas in order to suppress the carbon‐fixation reaction. The potential response was found to be different from the ambient gas, and we determined that several behaviors of the potential response were strongly related to the activities of the photochemical reaction and carbon‐fixation reaction. We next measured the potential when the illuminating conditions were changed to accelerate or decelerate photosynthesis. The shape of the potential response was found to be related to the increase or decrease of photosynthetic rate and can provide support for effective cultivation. © 2012 Wiley Periodicals, Inc.
