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); T0 (on raised table); T1 (3 d transplanted on sterile soil). Different letters in the same column indicate significant differences at *P < 0.01, not significant (n.s.). Data represent mean values of 6 replicates ± standard error.
