K⁺: Na⁺ ratios in shoots (a) and roots (b), and shoot: root Na⁺ ratio (c) of maize genotypes JD52 and FSY1 inoculated with arbuscular mycorrhizal fungus (Funneliformis mosseae) (AM) or without inoculation (NM) in 0 and 100 mM NaCl treatments assessed at 59 DAS. Data are means ± SE (n = 5), in each graph, data of traits were compared within each genotype, bars with different letters are significantly different (P ≤ 0.05)
