Does self incompatibility impose any restrictions on autogamy ? Give reasons and suggest the method of pollination in such plants.

Explanation

Self Sterility : In sore bisexual flowers, if the poilengrains fall on the stigma of the same flower, germination does not occur. But the same pollen grains germinates when they fall on the stigma of other flowers of the same species. It is a genetic mechanism to prevent self pollination.
E.g. : Abutilon, Passiffora. In these plants cross pollination only occurs. In some plants, the pollen grains become poisonous and make the flower wither if self pollination occurs. E.g. : Orchids.
