Percent dissimilarity (d-value), average within-group pairwise Pearson’s correlation – average between-group pairwise Pearson’s correlation, p < 0.05 and n = 4 (Kropf et al., 2004). Abbreviations: T0, samples before planting apple rootstock M26 and Con, H50 and Gamma, samples collected 8 weeks after the biotest (after planting M26); n.a., not analyzed.
