Characteristics of Plant Bioelectric Potential and Purification Function under LED Light

Abstract—Recently, plant factory has been establishing and takes off in world wide countries. In the plant factory, the growing environment can be controlled and the crop can also be controlled. The products are growing in an enclosed environment, therefore agricultural chemicals has no use. Secure and safe food producing system can be constructed. However, efficient production formula for the plant (for example vegetable) is not defined well. It is an effective way to control the growing environmental factors using physiology information which are directly obtained from the vegetable. Light plays a key role in plant growth. There is a difference in the amount of production due to light frequency. In this study, plant bioelectric potential is examined under light emitting diode (LED) which is used in plant factory. In future, plant physiological function and environmental response can be understood by directl
