Figure 5.

Shoot (a) and root (b) P 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 P concentrations: AM inoculation: F = 25.9 **, Mo: F = 0.3 ns, AM × Mo: F = 0.3 ns; two-way ANOVA results for root P concentrations: AM inoculation: F = 4.2 *, Mo: F = 0.7 ns, AM × Mo: F = 1.0 ns. Significance levels: * p < 0.05; ** p < 0.01; ns non-significant effect.
