Floral color change occurs in flowers in a wide range of angiosperm taxa that undergo a color change associated with their age, or after successful pollination. [3] [4]
Pollination by a specialist can result in high flowering synchrony, as asynchronous flowering can result in erratic attraction of a specialist to a site. [19] Showy floral displays tend to attract pollinators, [20] [21] and synchronous flowering can attract more pollinators to a population. High pollinator visitation to populations with high ...
A common phenotype of UV coloration is the “bulls-eye” pattern where a flower reflects UV light at the ends of the petals and absorbs UV light in the center. [4] This acts as a guide for pollinators to locate and find pollen. [4] Other flowers add the contrast between their reproductive parts (anthers and pistils) and their petals. [7]
