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

(N/A) Yes,self-incompatibility imposes a significant restriction on autogamy.
Reasons: Self-incompatibility is a genetic mechanism that prevents self-pollen (from the same flower or other flowers of the same plant) from fertilizing the ovules by inhibiting pollen germination or pollen tube growth on the stigma.
Method of Pollination: In such plants,pollination must occur through cross-pollination (allogamy). Since self-pollination is genetically blocked,the plant relies on external agents such as wind,water,or biotic agents (insects,birds,etc.) to transfer pollen grains from the anther of one flower to the stigma of another flower of the same species.
