Hormesis, screening and practical use of biostimulators in agriculture

Abstract

The term hormesis describes the biphasic response of any biological system to increasing the dose of the stress factor of a different nature, characterized in that low doses have stimulating, beneficial effects. In contrast, high doses cause harmful, inhibitory effects. The hormonal response is practically universal, being stimulated by the action of toxic substances, heavy metal ions, hormones, including physical factors. The standard type of response to different factors suggests installing these evolving mechanisms, so they are of particular interest in elucidating plant adaptation mechanisms to various stressors, including developing screening methods and practical use of biostimulators. The practical use of hormesis principles was the theoretical basis for elaboration and rational use of the biostimulator Reglalg in agriculture.
