Efficacy of plant growth regulator (PGR) in lieu of root growth and dynamics: A review

Abstract

Plant Growth Regulators (PGRs) have emerged as crucial supplements for optimizing root growth and dynamics in plants, thereby significantly influencing overall plant health and productivity. This study explores the pivotal role of PGRs in regulating root architecture, enhancing nutrient and water uptake efficiency, and fortifying plants against environmental stresses. It discusses the diverse mechanisms through which PGRs modulate gene expression, signal transduction pathways, and hormonal interactions to orchestrate root development. Furthermore, the abstract highlights the practical applications of PGRs in agricultural and horticultural practices, including their use in various application methods, dosage considerations, and timing strategies. By providing insights into the significance of PGRs as supplements for root growth enhancement, this abstract underscores their importance in promoting sustainable agriculture and ensuring global food security.
