Scarlet gilia (Ipomopsis aggregata) is a red to pink flowering plant which shows floral color plasticity within populations on the eastern slope of the Rocky Mountains. Anthocyanin is the red flavonoid pigment which gives these petals color and has been shown to act as protection from UV damage in plants by shielding chloroplasts and acting as an antioxidant. This study was conducted on seeds from red and pink flowering maternal plants at the Manitou Experimental Forest. After being counted and weighed, seeds were germinated in a growth chamber over the course of 23 days and were censused for germination rate every other day. Photosystem efficiency, anthocyanin content, chlorophyll content, and biomass were measured on germinated seedlings after the census was completed. Dark-flowering maternal plants yielded seeds and seedlings with higher biomass than light-flowering ones. Seeds from darker maternal plants also germinated faster than those from light maternal plants and had higher anthocyanin content. The hereditary nature of anthocyanin content thus suggests that higher anthocyanin levels are linked to measures of fitness such as higher seed weight, germination rate, and seedling biomass, indicating that UV protection provided by anthocyanin potentially increases the realized fitness of maternal plants.
