Abbreviations: +M, inoculated with arbuscular mycorrhizal fungi (AMF);
−M, non-inoculated with AMF; F, fertilization (df = 5); I, inoculation (df = 1); F
×
I, interaction between
fertilization and inoculation (df = 5); P, significant levels of each factor and interaction between them.
*The differences in traits between +M and −M were significant (P < 0.05); ns, the differences in traits between +M and −M were not significant; values shown wereaverages, calculated using 9 replicates for each treatment (±s.d. of the mean); values followed with different letters in the same row were significant different (P < 0.05)
