(A) Electrolyte leakage, (B) malondialdehyde (MDA), and (C) hydrogen peroxide (H2O2) content in the shoot of alfalfa plants grown without (0 mM NaCl: white bars) or with (120 mM NaCl: black bars) salt stress and submitted to different biofertilizers treatments; Ct: untreated control, M: inoculated with arbuscular mycorrhizal fungi, R: inoculated with rhizobium strain, C: amended with compost, MR: inoculated with the mixture AMF + rhizobium, CM: amended with compost and inoculated with the AMF, CR: amended with compost and inoculated with rhizobium, and CMR: amended with compost and inoculated with the mixture AMF + rhizobium. Means (± standard error) within the same graph followed by different letters are significantly different at p < 0.05.
