Herbivore-induced plant volatiles (HIPV) Bray’s Curtis Dissimilarity matrix was subjected to PERMANOVA to identify significant influence of Microbe treatment (BS, BL, L, S) and Genotype (B73, PHJ40, PHG84, OH43, PA91) on HIPV composition. Bray’s dissimilarity matrix was produced using vegdist() function and the PERMANOVA was conducted using the adonis() function, both of the vegan package. Block was used as the constraining strata condition. Asterisk denote factor significance: P = 0 ‘***’; 0.001 ‘**’; 0.01 ‘*’; 0.05 ‘⋅’.
