Effects of plant growth regulators on physiological and phytochemical parameters in medicinal plants under stress conditions

Abiotic stresses are now recognized as the greatest and most serious threat for agricultural productivity worldwide. Abiotic stresses have several detrimental effects on plants, including inhibition, cessation of various plant metabolic processes, slowing down carbon fixation, increasing oxidative damage, and ultimately reduced yield. Several physiological and agricultural methods are used to reduce the negative effects of stress and to stimulate stress tolerance in plants. The use of plant growth regulators is one of the promising and practical strategies to increase crop productivity under stress conditions
