Promotive Role of 5-Aminolevulinic Acid or Salicylic Acid Combined with Citric Acid on Sunflower Growth by Regulating Manganese Absorption.

ABSTRACT: Manganese (Mn) is an essential nutrient in most organisms. Establishing an effective regulatory system of Mn absorption is important for sustainable crop development. In this study, we selected sunflower as the model plant to explore the effects of 5-aminolevulinic acid (ALA) or salicylic acid (SA) combined with citric acid (CA) on Mn absorption. Six-leaf-old sunflower plants were exposed to 0.8 g kg^-1 Mn for one week and then treated with chelating agents, i.e., CA (10 mmol kg^-1), and different concentrations of ALA and SA for one week. The results showed that Mn-treated plants had significantly increased H₂O₂, O₂^- and MDA contents in leaves compared with the control. Under the Mn + CA treatment, ALA or SA2 significantly ac
