Mean comparison of chlorophyll concentration in C. equisetifolia (a) and C. glauca (b) plants inoculated with Rhizophagus aggregatus (Ra), Rhizophagus fasciculatus (Rf), or Rhizophagus intraradices (Ri) in the presence of 0, 150, or 300 mM of NaCl. Values are the mean of five plants. Standard deviations are displayed as bars, and bars sharing the same letter are not significantly different at p < 0.05 according to the Steel–Critchlow–Fligner test (“a” = lowest values and “b” = highest values). Data presented are representative of two independent experiments. Lowercase letters (a-b) indicate significant differences regarding AMF inoculation. Uppercase letters (A-C) indicate significant differences regarding NaCl concentrations. Uppercase letters in parentheses (A)-(B) indicate significant differences regarding species
