List of terpenes analyzed across the three years and environmental conditions (auto-scaled values) differentiated between genotypes (H1, Boléro, I2 and K3) by ANOVA with a p value < 0.025 and Tukey’s honest significant difference (HSD) test, which highlighted pairs of genotypes with significant differences in accumulation of each metabolite (x).

Within each sub-family metabolites are ranked from those with significant differences between H1 and the three resistant genotypes to those with significant differences between H1 and two or only one resistant genotype.
