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 Zn concentration in grain and straw (a, c) and on Zn content in grain and straw (e, g) in bread wheat, and Zn concentration in grain and straw (b, d) and on Zn content in grain and straw (f, h) in barley. 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)
