Fig. 3

Flavonoid concentrations measured by spectrophotometry in the phenotypes of S. littorea from the polymorphic (Barra and Louro) and non-polymorphic (Trafalgar and Breña) petal-color populations. Mean (± s.e.) concentrations of anthocyanins and non-anthocyanin flavonoids in the four studied plant tissues are showed. Pink, pink-white striped and white bars represent fully pigmented, PAL and WAL phenotypes, respectively. Letters indicate significant differences (P < 0.05) from post hoc multiple comparisons among phenotypes within each population. Note the different scale between plant tissues and flavonoid types.
