Mention two strategies evolved to prevent self-pollination in flowers.
Self-pollination includes the switch of pollen from the stamen to the pistil of the identical flower. Two techniques that have advanced to save you self-pollination in plants are as follows: (1) In positive plants, the stigma of the flower hasthecapability to save you the germination of pollen grains and hence, save you the boom of the pollen tube.It is a genetic mechanism to save you self-pollination known as self- incompatibility. Incompatibility can be among people of the equal species or among people of different species. Thus, incompatibility prevents breeding. (2) In a few plants, the gynoecium matures earlier than the androecium or vice-versa. This phenomenon is known asprotogyny or protandry respectively. This prevents the pollen from coming in touch with the stigma of the identical flower.
