Abstract

As one of the active oxygen species that is widely generated in many biological systems and mediates various physiological and biochemical processes in plants, exogenous hydrogen peroxide (H₂O₂) in very low concentrations improves salt-tolerance in some plant species. Therefore, two field experiments were conducted in 2013/14 and 2014/15 to study the effect of foliar sprays at concentrations of 1 and 2 mM H₂O₂ on growth, yield, plant water relations, osmoprotectants and the activity of antioxidant system in two onion varieties grown under saline soil condition (EC_e = 7.94 - 8.81 dS/m). Exogenous H₂O₂ enhanced salt stress tolerance in onion plants by reducing the endogenous H₂O₂ and lipid peroxidation, and increasing enzymatic (i.e., superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase) and non-enzymatic antioxidant (i.e., ascorbic acid and glutathione) activity. Moreover, H₂O₂ application significantly affected photosynthetic efficiency and plant water status as evaluated by relative water content and membrane stability index. These results were positively reflected by the increase in plant growth, productivity and water use efficiency under salt stress conditions. H₂O₂ may participate in enzymatic and non-enzymatic antioxidant activity, inducing salt-tolerance in onion plants.
