Fig. 2.
Norm of reaction plots illustrating the effects of ploidy level, drought stress and defoliation on phytochemistry (mean ± SE). For each trait (box), the left panel represents trait values averaged across genotypes from the same ploidy level when exposed to all combinations of drought stress and defoliation. Model results above the left panel do not account for genotypic variation. The right panel represents mean response of eight different diploid and triploid genotypes when exposed to the same treatment combinations. Model results above the right panel account for genotypic variation. Both models contain the same fixed model variables and interaction terms. Only values of model variables with P ≤ 0.100 are shown. dw= dry weight. Data points are horizontally jittered to reduce overlapping.
