Figure 4

Soil-pH measured in the peripheral (a) and central compartments (b). Means ( ) and standard errors for the pre-experimental unseeded (black diamond), post-experimental unseeded (black square), hyphosphere (white square), mycorrhizosphere (white triangle), and rhizosphere (white circle) treatments are shown. Shared letters designate regression equations having slopes that are not significantly different according to ANCOVA ( ).
