Figure 6.

Shoot (a) and root (b) N concentrations (mean ± SE, n = 4) of sweet sorghum exposed to different concentrations of Mo. −M and +M represent non-AM inoculation and inoculation with Claroideoglomus etunicatum BEG168, respectively. Different letters over the bar represent significant differences between the means among different treatments using one-way ANOVA followed by Duncan’s multiple range test (p < 0.05). Two-way ANOVA results for shoot N concentrations: AM inoculation: F = 31.8 **, Mo: F = 0.9 ns, AM × Mo: F = 1.7 ns; two-way ANOVA results for root N concentrations: AM inoculation: F = 15.3 **, Mo: F = 1.3 ns, AM × Mo: F = 0.9 ns. Significance levels: * p < 0.05; ** p < 0.01; ns non-significant effect.
