Influence of Ambient Environmental Factors on the Evaluation of Physiological Activity of Bonsai Using Plant Bioelectric Potential

The purpose of this study was to evaluate the physiological activity of bonsai using plant bioelectric potential. In the experiment, we compared the differences in plant bioelectric potential responses depending on the measurement month for twelve months and the correlation between the response and five ambient environmental factors: temperature, humidity, atmospheric pressure, carbon dioxide concentration, and illumination.
