The values (mean ± standard error, n = 10) with different letters within columns are statistically different (P ≤ 0.05) according to Duncan’s multiple range test. AMF, arbuscular mycorrhizal fungi; CK, without AMF inoculation + without salinity-alkalinity; M, with AMF inoculation + without salinity-alkalinity; S, without AMF inoculation + with salinity-alkalinity; and MS, with AMF inoculation + with salinity-alkalinity.
