For example, jasmonic acid can be used to simulate an herbivore attack on plants and thus, induce plant defences. [19] The use of jasmonic acid on tomato (Lycopersicon esculentum) resulted in plants with fewer but larger fruits, longer ripening time, delayed fruit-set, fewer seeds per plant and fewer seeds per unit of fruit weight.

Developmental bioelectricity is the regulation of cell, tissue, and organ-level patterning and behavior by electrical signals during the development of embryonic animals and plants. The charge carrier in developmental bioelectricity is the ion (a charged atom) rather than the electron , and an electric current and field is generated whenever a ...
Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .
Gold-leaf electroscope, showing induction (labelled polarity of charges), before the terminal is grounded. Using an electroscope to show electrostatic induction. The device has leaves/needle that become charged when introducing a charged rod to it. The leaves bend the leave/needle, and the stronger the static introduced, the more bending occurs.
Plant defense against herbivory or host-plant resistance is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Many plants produce secondary metabolites , known as allelochemicals , that influence the behavior, growth, or survival of herbivores.
The effects of electrotropism on plant growth can be witnessed in the grape “Uslu”. An electric field has similar forces as a magnetic field. A magnetic field can be created by using an alternating electric field. Thus, a magnetic field may have similar effects on plants as an electric field used in electrotropism.
The induction of plant-induced resistance to pathogen protection was identified in 1901 and was described as the "system of acquired resistance." Subsequently, several different terms have been used, namely, "acquired physiological immunity", "resistance displacement", "plant immune function" and "induced system resistance."
Faraday's law of induction (or simply Faraday's law) is a law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (emf). This phenomenon, known as electromagnetic induction , is the fundamental operating principle of transformers , inductors , and many types of electric ...
