Bullseye size differs extensively from sunflower to sunflower, varying from small circles in the middle of the flower to large bullseyes that take up the entire petal. Sure enough, pollinators visited flowers with medium-sized bullseyes 20 to 30 percent more regularly than those with big or small bullseyes– in line with what research study on other plants has discovered. When the researchers compared the quantity of heat coming from flowers with bullseyes of different sizes, they discovered no difference at any point in the day.Finally, they observed that sunflowers with large bullseyes were sourced from drier environments, whereas sunflowers with little bullseyes came from more damp environments.

Sure enough, pollinators went to flowers with medium-sized bullseyes 20 to 30 percent more regularly than those with small or large bullseyes– in line with what research on other plants has actually found. To investigate that possibility, the researchers outlined the variation in size of UV bullseyes for the typical sunflower (Helianthus annus) across North America by using their cultivated individuals as agents for their source populations. Todescos first idea was that the bullseyes, which consist of UV-absorbing pigments, might secure sunflowers from excess solar radiation.
