Salinity is the primary restriction factor for vegetation conservation and the rehabilitation
of coastal areas in Eastern China. Arbuscular mycorrhizal fungi (AMF) have been proved to have
the ability to alleviate salt stress in plants. However, the role of AMF in relieving salt stress among
indigenous trees species is less well known, limiting the application of AMF in the afforestation
of local area. In this study, a salt-stress pot experiment was conducted to evaluate the effects of
AMF on Zelkova serrata (Thunb.) Makino, a tree species with significant potential for afforestation
of coastal area. The Z. serrata seedlings inoculated with three AMF strains (Funneliformis mosseae 1,
Funneliformis mosseae 2, and Diversispora tortuosa) were subjected to two salt treatments (0 and
100 mM NaCl) under greenhouse conditions. The results showed that the three AMF strains had
positive effects, to a certain extent, on plant growth and photosynthesis under normal condition.
However, only F. mosseae 1 and F. mosseae 2 alleviated the inhibition of growth, photosynthesis,
and nutrient uptake of Z. serrata seedlings under salt stress. The two AMF strains mitigated
salt-induced adverse effects on seedlings mainly by increasing the leaf photosynthetic ability and
biomass accumulation by reducing Na+
content, increasing P, K+
, and Mg2+ content, as well as by
enhancing photosynthetic pigments content and the stomatal conductance of leaves. These results
indicated that AMF inoculation is a promising strategy for the afforestation of coastal areas in
Eastern China.
