Similarly, in a pot experiment with wheat, the Zn uptake
and tissue Zn concentration were reduced by P application
in the presence of AM colonization but unaffected
in its absence (Ryan and Angus 2003). The negative
effect of P applications on the grain Zn concentration of
wheat was also documented in several field studies
(Ryan and Angus 2003; Ryan et al. 2008; Zhang et al.
2012).
