Telechory

from Wikipedia, the free encyclopedia

Telechory or long- distance propagation describes a group of propagation mechanisms in plants . The common feature is that the seeds are spread over long distances.

The demarcation of long-range propagation (telechory) and close-up propagation (engychory or topochory) is controversial. Some authors speak of long-range spread from distances of 100 meters, (1932–35) others only from 10 km.

Otherwise, telechory is understood to mean many different mechanisms of propagation such as anemochory or zoochory .

A specialty is the phenomenon of antitelechory in desert plants. Here the seed is deposited as close as possible to the mother plant in order not to carry it out of the area of ​​possibly very small water resources.
