The effect of exogenously applied plant growth regulators and zinc on some physiological characteristics and essential oil constituents of Moldavian balm (Dracocephalum moldavica L.) under water stress.

ABSTRACT: Cost-effective exogenous application of some antioxidant, viz. salicylic acid (SA) and ascorbic acid (AA), and essential micronutrient elements like Zn might alleviate the harmful impacts of drought stress. Here, we evaluated the interaction of foliar-sprayed SA (1 mM), AA (10 mM), and Zn (3 g L^-1) and irrigation regime (normal irrigation, moderate water stress, and severe water stress) by assaying an array of agronomic, physiological, analytical and biochemical parameters of Moldavian balm (Dracocephalum moldavica L.). Accordingly, the SA and AA treatments reduced the harmful effects of moderate and severe drought stress. Well-watered plants applied with Zn had the highest biomass yield (4642.5 kg ha^-1). Severe water stress decreased plant biomass, essential o
