Arbuscular mycorrhizal fungi (AMF) association increases plant stress tolerance. This study aimed to
determine the mitigation effect of AMF on the growth and metabolic changes of cucumbers under
adverse impact of salt stress. Salinity reduced the water content and synthesis of pigments. However,
AMF inoculation ameliorated negative effects by enhancing the biomass, synthesis of pigments, activity
of antioxidant enzymes, including superoxide dismutase, catalase, ascorbate peroxidase and glutathione
reductase, and the content of ascorbic acid, which might be the result of lower level lipid peroxidation
and electrolyte leakage. An accumulation of phenols and proline in AMF-inoculated plants also mediated
the elimination of superoxide radicals. In addition, jasmonic acid, salicylic acid and several important
mineral elements (K, Ca, Mg, Zn, Fe, Mn and Cu) were enhanced with significant reductions in the uptake
of deleterious ions like Na+. These results suggested that AMF can protect cucumber growth from salt
stress..
