Abstract

Category: Agricultural Science Tags: electromagnetic fields, plant physiology, electric field technology, magnetic field effects, crop production, gene expression, reactive oxygen species DOI: 10.1021/acsagscitech.5c00865 URL: doi.org Overview All living organisms on Earth are naturally exposed to planetary electromagnetic fields, which interact with biological processes in various ways. In agriculture, applications typically employ these fields separately through distinct technologies and methodologies. Electric and magnetic fields are inherently linked, as each can generate the other when the fields are dynamic. Findings - No systematic review has described the effectiveness or mechanisms by which electric and magnetic fields impact plant growth and development until now. - This review provides theoretical, technological, and practical comparisons of electric and magnetic field effects on plants. - A new model is proposed to clarify the mechanistic convergence of both field types. - Four predominant mechanisms suggested: - Changes in membrane permeability - Production of reactive oxygen species and triggering antioxidant responses - Improvements in ion absorption and transport - DNA alterations and gene expression patterns Conclusion Applications of electric and magnetic fields in agriculture are not limited to seed treatment and have potential for diverse uses in real-world crop production.

Main findings

This review compares theoretical, technological, and practical aspects of electric- and magnetic-field effects on plants and proposes a model for mechanistic convergence. It summarizes four predominant suggested mechanisms: changes in membrane permeability, ROS/antioxidant responses, improved ion absorption/transport, and DNA/gene expression alterations, and notes potential applications beyond seed treatment for crop production.
