Polychory

Seed of the polychrome silver birch

Under Polychorie means the dispersal of seeds and fruits by different vectors . Birch seeds can be spread, for example, by the wind ( anemochory ), by water ( hydrochory ) or by clinging to the plumage of waterfowl ( epichory ). Polychory must be distinguished from heterocarpy , the formation of different fruits for different vectors on an individual.

The expression was first used in 1928 by E. Ulbrich in his work Biology of Fruits and Seeds (Carpobiology) on page 200.
