FIGURE 4.
Non-metric multidimensional scaling (NMDS) ordination constructed with a Bray-Curtis dissimilarity matrix of HIPV peak area data. Plant biomass (Shoot dry and weight biomass, dry root biomass, root:shoot ratio) and rhizosphere bacterial community richness parameters (observed richness, Chao1 index, Shannon Evenness) were correlated to NMDS1 and NMDS2 points using the envfit() function of the vegan package in R; significance is reported in Table 7. Significant vectors displayed with an asterisk: P = 0 ‘***’; 0.001 ‘**’; 0.01 ‘*’; 0.05 ‘.’.
