Statement 1: Pollination does not guarantee fertilization; it is merely the transfer of pollen to the stigma. Post-pollination events, including pollen-pistil interaction, must occur to ensure fertilization.
Statement 2: The sequence of events from pollen deposition on the stigma until the pollen tubes enter the ovule is correctly referred to as pollen-pistil interaction. This statement is correct.
Statement 3: Pollen-pistil interaction involves both the promotion and rejection of pollen, depending on compatibility. Therefore, the statement that it involves only promotion is incorrect.
Statement 4: Pistils do have the ability to recognize pollen and can discriminate between compatible and incompatible pollen types.
Thus, Statement 2 is the correct option.
