Na⁺ (A,B), K⁺ (C,D), K⁺/Na⁺ ratio (E,F) and Ca²⁺ content in roots (G) and leaves (H) of Kandelia obovata treated with different salt concentrations and with 100 µM sodium nitroprusside (SNP, a NO donor), hemoglobin (Hb, a NO scavenger), or Nω-nitro- l-arginine methyl ester (l-NAME, a NO synthase inhibitor). Mean (± SD) was calculated from three replicates for each treatment. Bars with different letters are significantly different at p ≤ 0.05, applying Tukey’s HSD test.
