AUTOCHORE [3 records]

Record 1 2017-11-23

English

Subject field(s)
  • Ecology (General)
  • Plant Biology
  • Botany
CONT

If the dispersal is achieved only through devices that the plant itself produces then it is spoken of self-dispersal or autochory. If extern factors such as wind, water, animals, etc. are involved, then the mode of dispersal is called allochor. Only rarely are the seeds spread on their own, usually the whole seed-containing fruit is scattered. Among the autochor modes of dispersal is flinging and spurting of seeds.

OBS

Compare with "autochore" (or "autochorous plant") and "autochory".
