Solution
The correct option is A Asteraceae
The correct answer is A.Saprophytic self-incompatibility outcome of the interaction between the pollen tube and the style is determined by the genotype of the sporophyte (diploid tissue) S-locus products are synthesized before completion of meiosis growth of the pollen tube arrests at the surface of the stigma. This is a genetic mechanism in which the germination of pollen grains or the pollen tube growth in the pistil is inhibited which prevents the pollen from fertilizing the ovules. Such plants pollinate by the process of cross-pollination.
Example: Asteraceae, Brassicaceae, Betulaceae, Polemoniaceae, Caryophyllaceae.
