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.
