प्रश्न
Does self incompatibility impose any restrictions on autogamy? Give reasons and suggest the method of pollination in such plants.
उत्तर
Self-incompatibility imposes restriction to autogamy. The device to prevent inbreeding is self-incompatibility or self-sterility. This is a genetic mechanism and prevents self-pollen (from the same flower or other flowers of the same plant) from fertilising the ovules by inhibiting pollen germination or pollen tube growth in the pistil. Self-incompatiblity is overcome by mixed pollination.
