From: Exogenous spermidine-induced changes at physiological and biochemical parameters levels in tomato seedling grown in saline-alkaline condition

Figure 1

Effects of exogenous Spd on contents of NO 3 −-N (A) and NH 4 +-N (B) in leaves of tomato seedlings under salinity-alkalinity mixed stress (nutrient solution with 75 mmol/L saline-alkaline solution; NaCl:Na 2 SO 4 :NaHCO 3 :Na 2 CO 3  = 1:9:9:1). Data represent means of three replicates. Bars represent the mean ± SE (P < 0.05) of at least three independent experiments.
