摘要

Seed treatments, crucial for safeguarding seeds and optimizing crop yield, have witnessed a shift towards environmentally friendly alternatives to chemical treatments. Plasma and magnetic fields have emerged as promising technologies in agriculture, offering a sustainable approach to enhancing crop development. Exposure to magnetic fields and plasma induces positive effects on plant growth, influencing gene expression and ultimately boosting crop productivity. These technologies induce changes at the molecular level, impacting epigenetic, transcriptomic, proteomic, and metabolic processes. These changes manifest in enhanced germination rates, improved early seedling development, optimized phytohormone levels, and enhanced activity of metabolic and defense enzymes. This review delves into the application of plasma and magnetic fields in agriculture, highlighting their potential to enhance cereal production. Recent research demonstrates that processing diverse cereals like wheat, rice, barley, and maize using these technologies leads to significant improvements in plant growth, yield, and stress resilience. The development of more effective and scalable plasma and magnetic field systems, crop-specific treatment parameter optimization, and precision agriculture application exploration will be the main areas of future study.
