Role of Penconazole in salt stress amelioration in Sesamum indicum L.

ABSTRACT

Sesame (Sesamum indicum L.) is one of the world’s important oil crops. The aim of the present study was to investigate the effects of salt stress on physiological and biochemical parameters of sesame and assess the improvement of salt tolerance by Penconazole (PEN). Plants were treated with various NaCl concentrations (0, 50, 100, and 200 mM) without or with PEN (15 mg L^?1). Salt stress inhibited the growth in sesame. Our results showed sesame plant under salinity used of the enzymatic and non-enzymatic system and compatible osmolytes to overcome on oxidative and osmotic stress, respectively. PEN improved the growth and reduced the negative effects of salinity in sesame. In fact, PEN increased the resistance of this plant under salt stress by improving the antioxidant system and osmotic regulation. Thus, this compound can be used as stress-ameliorating agents in this crop plant.
