Role of melatonin seed priming on antioxidant enzymes and biochemical responses of Carthamus tinctorius L. under drought stress conditions

Drought has profound effects on productivity of crops in arid and semi- arid regions causing deleterious effects on the functions of crops leading to oxidative stress. In the present study, extensive melatonin seed priming experiments were conducted to assess the antioxidant enzymes and biochemical...
