Interactive effects of melatonin and salicylic acid on Brassica napus under drought condition

It is imperative to understand the synergetic actions of Melatonin (MET) and salicylic acid (SA) in counteracting drought stress. A pot experiment was performed investigate interactive effects exogenously applied MET SA on morphology, physiology, biochemical characteristics drought-stressed canola (Brassica napus). Two cultivars (Super Faisal canola) were used. (0.1 µM) (0.50 mM) as seed priming foliar spray. Plants exposed severe (45% field capacity) at reproductive stage. Drought stress caused a significant reduction shoot length (19%), plant fresh (15%) dry (17%) biomass, yield (30%), photosynthetic rate (43%), water potential (29%) osmotic (33%) values. Increased activity free amino acids (20%), total soluble sugars (5%), different antioxidant enzymes like catalase (27%), peroxidase (23%), superoxide dismutase (20%) ascorbate (35%), recorded under drought. Seed application reduced negativity Priming seeds with MET, well spray, most effective treatments, showing growth criteria (22% increase height, 46% 40% biomass), components (49%), (54%) (28%), endogenous (16%) content. Super cultivar showed better than canola. Study that has induce resistance enhance plants'
