Environmental Microbiome

Table 1 Influence of the rootstock and the scion genotypes on the α-diversity (richness = Chao1, diversity = Simpson) and the β-diversity metrics (Bray-Curtis dissimilarity) amongst bacteria, fungi and AMF, in the rhizosphere (RH) and the root endosphere (RE). P-values were calculated using two-way Anova and were considered as significant when the p-value < 0.05, PVE = percentage of variance explained
