2. Awns and other appendages on the seed dispersal unit of plants aid in dispersing the seed to a germination site (1–3).Hairs, wings, and hooks influence the route of seeds from the mother plant to a surface by wind or animal dispersal [phase I dispersal ()].Hygroscopically active Awns propel seeds on the ground through coiling and uncoiling (5, 6) and, thus, mainly affect the movement of the
