Fig. 8From: Nitrogen availability prevents oxidative effects of salinity on wheat growth and photosynthesis by up-regulating the antioxidants and osmolytes metabolism, and secondary metabolite accumulationEffect of nitrogen (50 and 100 mg kg− 1 soil) supplementation on the activity of (a) nitrate reductase and (b) nitrogen content in Triticum aestivum L subjected to salinity stress. Data is mean (±SE) of three replicates, bars denoted by different letters are significantly different at P < 0.05Back to article page
