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

Explanation

Self incompatibility impose limitation of self fertilisation. For this majority of flowering plants produce bisexual flowers and while pollen grain comes in contact with stigma of pistil of sme flower and continues self pollination. In breeding results in depression due to continuation of self pollination of this type. So many remedies have been developed to prevent self pollination and encourage cross pollination. Self sterility is the bigger remedy to prevent self fertilisation
Self sterility is seen in some bisexual flowers. If transfer of pollen grain occurs on the stigma of the same flower then germination does not take place. If pollen transfers on the stigma of another flower of the same species then it germinates. These genetic devices is for preventing self pollination.
