Outline of Final Research Achievements

The plant bioelectric potential responses are correlated with the physiological activity. Thus, we considered that the cultivation environment operating system will be improved by using the bioelectric potential response as an evaluation index. In this study, we aimed to develop the cultivation environment control system using plant bioelectric potential.
At first, we observed the bioelectric potential response when single wavelength and plural wavelengths were irradiated on the plant. These results showed that the difference in potential response and photosynthetic rate depended on the light intensity rate of plural wavelengths.
Second, we developed the light intensity control system using plant bioelectric potential. Our developed system can operate correctly depending on the feedback signal made from the plant bioelectric potential. We suggested that the system contribute to the improvement of the cultivation environment control system and the energy saving effect.
