Treatments: C (control without inoculation); GA5 (Rhizophagus irregularis GA5 strain inoculation); GC2 (Rhizophagus irregularis GC2 strain inoculation); GA5 + GC2 (mixture 1 : 1 of GA5 and GC2 strains); MD (mycorrhizal dependency); T2 (1-year plants on sterile soil); T3 (7 d after transplant to nonsterile soil). Different letters in the same column indicate significant differences at *P < 0.05, **P < 0.01, ***P < 0.001, not significant (n.s.). Data represent mean of 6 replicates ± standard error.
