Answer in Brief

Why does self-pollination not lead to seed formation in self-incompatible species?

Advertisements

Solution

The plants which exhibit the phenomenon of self-pollination have the ability to prevent germination of pollen grains and thus, prevent the growth of the pollen tube on the stigma of the flower. This prevents the fusion of the gametes along with the development of the embryo. As a result, no seed formation takes place.
