Dispersal of Seeds by Gravity Large, round, heavy fruits just drop straight off the tree onto the ground when they are ripe.
Large, round, heavy fruits just drop straight off the tree onto the ground when they are ripe.
If they have a tough outer shell, they may roll some distance from the parent plant. The higher up the tree they are, and the larger they are, the further they can roll.
If they have a soft skin, they may break open when they hit the ground and the individual seeds may be scattered.
On lower-growing plants, many fruits and seeds are also heavy enough to fall to the ground without any other help.
When they reach the ground, some seeds are taken further from the parent plant by animals or water.
Seeds dispersed by gravity include:
Passionfruit Hedychium Cerinthe Commelina Canna Salvia
