“…Many papers have reported that the potential changes with environmental conditions such as illumination, temperature, humidity, gases, watering, and trauma [8][9][10][11]. In addition, several studies have attempted to monitor not only plant activities but also the ambient environment of plants [13], and other studies have attempted to optimize the growing environment and efficiency by using information on the bioelectric potential as a control signal [14]. Therefore, measurement of the bioelectric potential is a promising method of evaluating and monitoring plant activities by physical quantities.…”

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 carbonfixation 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.

SUMMARY We focused on measurement of the bioelectric potential as a method of evaluating plant activities and supporting effective cultivation. In this study, we investigated the bioelectric potential response due to photochemical reactions and carbon‐fixation reactions in the process of photosynthesis. First, we measured the bioelectric potential when illumination was started and stopped, under N2 gas conditions in order to suppress the carbon‐fixation reaction and respiration. It was found that the amplitude of the potential response was related to the illumination intensity and the wavelength. We considered that the amplitude of the potential response under N2 conditions indicated the activity of the photochemical reaction. Based on this result, we investigated the potential response under room air conditions. If the carbon‐fixation reaction was deactivated by a long dark period, a significant potential decrease was observed when illumination started. In contrast, if the carbon‐fixation reaction remained active during a short dark period, the potential decrease was slight or none regardless of the photosynthetic rate. Therefore, we considered that this potential decrease is related to the activation of the carbon‐fixation reaction. Next, we investigated the relationship between plant activity and the potential response when illumination stopped. The results showed that the amplitude of the response is related to the illumination intensity and the respiration rate. We conclude that plant activities such as photosynthesis can be evaluated in more detail by measurement of the bioelectric potential, as an application of this study. © 2013 Wiley Periodicals, Inc.

“…Each time the running window was calculated, the resulting value was compared to the threshold. The slope threshold value was selected from the results of previous experiments (Hirama et al, 2008). By selecting the threshold from the slope rise and fall characteristics, the lighting on/off conditions were controlled.…”

“…The initial hypothesis, that the mushroom fruit body produces a bioelectric potential signal that responds to various environmental changes (Hirama et al, 2008), was then revised to use the fruit body as a bio-sensor for controlling the illumination timing. Yanagibashi et al (2009) observed that an algorithm to synchronize illumination timing with the Maitake biorhythm, which uses the bioelectric potential rise and fall slope characteristics, can induce a production increase at mushroom farms.…”
