要約(英語): We are attempting to establish an evaluating and monitoring method of photosynthesis using bioelectric potential of plants. In this study, we focused on a rapid biopotential response caused by the photochemical reaction in the first and speedy part of photosynthetic reactions. We propose an active method to evaluate intensity of the photochemical reaction that controls photosynthetic rate by using a frequency response of biopotential to blinking illumination. We have investigated the relation between the frequency responses of biopotential and the intensity of the photochemical reaction evaluated by a chlorophyll fluorescence measurement of leaves. The results showed that the frequency responses of biopotential to blinking illumination correlated with the amount of photon absorption calculated from the quantum yield by the chlorophyll fluorescence measurement. Finally, we concluded that the blinking illumination induced the rapid biopotential response that was mainly attributed to the photochemical reaction. Therefore, our proposed method could be available to evaluate the photosynthetic rate with higher accuracy than conventional method using bioelectric potential response of plants.
