Effects of above ground pathogen infection and fungicide application on the root-associated microbiota of apple saplings

Table 1 Variation in the root-associated bacterial community of apple saplings in dependence on pathogen infection, over time and by other variables. The differences in alpha and beta diversity are summarized for the L- and T-compartment. Effect sizes in beta diversity were assessed by PERMANOVA based on DEICODE distance matrices, while differences in Shannon diversity were analyzed based on generalized least square models (GLS). Significant results (p < 0.05) are in bold
