Determining the Impact of the AM-Mycorrhizosphere on “Dwarf” Sunflower Zn Uptake and Soil-Zn Bioavailability

Figure 1

Schematization of the compartmental pot system (a) showing the proliferation of hyphae across the dividing filter. The inoculum (or control) substrate layer is shown. Seeds were sown in the central compartment (CC) while the soil-Zn treatments were incorporated in the surrounding peripheral compartment (PC) representing either the rhizosphere (b), mycorrhizosphere (c), or hyphosphere environments (d).
