From: The mycorrhizal pathway of zinc uptake contributes to zinc accumulation in barley and wheat grain
Effect of Zn application and AMF inoculation with Rhizophagus irregularis (grey bars) or mock-inoculation (white bars) on grain yield, straw dry weight (dw), number of kernels per spike, and mean kernel weight of bread wheat (a, c, e, g, respectively) and barley (b, d, f, h, respectively). Plants were sampled at physiological maturity (Zadoks growth stage 90). Values are mean ± SEM, n = 5. Means followed by the same letter are not significantly different (P > 0.05, see text for further details)
