Autochory

Ordinary pasque flower in the backlight - it is one of the plants that herpochor can spread itself

Autochory (from the Greek αὐτός autós , German 'self' and χωρεῖν chōreín , German 'move forward, wander' ) or self- propagation describes the independent spread of seeds or fruits without the help or cooperation of external forces (wind, water, animals). In contrast to this are plants, the fruit of which is dependent on external forces for the seed to spread and germinate; Allochorie (external spread).

The autochory as the propagation mechanism of plants is even more finely divided into:

• Ball autochory , self- scattering , also ballochorie , the spread through centrifugal mechanisms
  • Juice pressure spreader
  • Dehydration spreader
• Herpautochory, herpochory , trypanochory , the spread through soil crawlers and drills
• Blastautochory, blastochory , the spread by self- offshoots .
• Barautochory , self-sowing, here the fruit stalks incline to the ground to spread the seeds, like with the two-leaved squill .
• Barochory , the spread through gravity, falling fruits, can also be understood as foreign spread through gravity or as achory (non-spread).
