Many fruits burst with a sudden jerk because of which the seeds are scattered a few yards from the parent plant. This type of dispersal of seeds is known as :

Anemochory
Hydrochory
Autochory
Zoochory

The dispersal of seeds by the plant itself through mechanisms like sudden bursting of fruits is known as Autochory.
Autochory refers to seed dispersal that is achieved by the plant itself, without reliance on external agents like wind, water, or animals. This can happen through various mechanisms, including explosive dehiscence of fruits or pods, where tension builds up in the drying fruit wall leading to a sudden burst that ejects the seeds.
Anemochory is dispersal by wind (e.g., dandelion seeds). Hydrochory is dispersal by water (e.g., coconut). Zoochory is dispersal by animals (e.g., seeds consumed and excreted, or seeds attached to fur). The description provided clearly matches the definition of autochory via an explosive mechanism.
