Organic acids in maize root exudates under different AMF symbiosis levels (ppb). (a ~ j) show the differences in p-hydroxybenzoic acid, protocatechuic acid, vanillic acid, syringic acid, citric acid, p-coumaric acid, chlorogenic acid, caffeic acid, succinic acid, and ferulic acid secretion in different growth stages under different treatments. Different colored blocks in each stacked histogram represent different growth maize periods: orange blocks refer to R4 (dough stage), green blocks refer to R2 (blister), purple blocks refer to R1 (silking), yellow blocks refer to VT (tassel), and blue blocks refer to V12 (twelve leaf). Analysis of differences between groups was performed for different treatments of the same growth phase shown in each stained histogram with identical lowercase letters denoting no significant differences between treatments (P > 0.05) and with different lowercase letters denoting significant differences between treatments (P < 0.05). Lower case letters in figures differently indicate significant differences between treatments (p<0.05)
