Sun-Tracking Solar Furnaces in High Arctic Flowers: Significance for Pollination and Insects
Heliotropic flowers ( Dryas integrifolia , Papaver radicatum ) act, in sunshine, as solar reflectors, their corollas focusing heat on the sporophylls. Considerable intrafloral temperatures are generated. Winds above 3.8 meters per second and cloud abolish the effect. Insects that bask in the flowers...
