ABSTRACT

This chapter presents a snapshot of the work that scientists have done on electromagnetic phenomena in plants. It gives a brief explanation of the measurable electrical parameters: current, voltage, potential difference, resistance/conductivity, direct and alternating current, inductance, capacitance, impedance, phase angle and redox; and the parameter P-value that can be calculated. Some parameters appear to be promising tools to monitor processes or status in plants or plant tissues. Certainly, the rapid development in the domain of sensors, artificial intelligence and the Internet of things will help to further develop some of these methods into a system that will expand the growers’ toolbox for monitoring plant growth and allow them to make better informed decisions. Bioelectric methods can also help with simple and cheap comparisons of the product’s internal (health) quality. Numerous methods for influencing electromagnetic plant growth have been the subject of research. To the knowledge of the author, none have really shown a breakthrough so far, but it is starting to be accepted that plant growth is not just a story about particles. More in-depth and systematic work is needed to analyse and integrate what has been discovered in order to apply the elements of energy and potential of electricity to better manage plant growth needs.
