Question

Which of the following statement is correct?

• A. Pollination gives the guarantee of the promotion of post-pollination events that lead to fertilisation
• B. The events ‘from pollen deposition on stigma until pollen tubes enter the ovule’ are together referred to as pollen-pistil interaction
• C. Pollen-pistil interaction is a dynamic process involving pollen recognition followed by only promotion (not rejection) of the pollen
• D. Pistil has no ability to recognise the pollen, whether right or wrong type

Answer 1

Answer: (B)

The statement in option (b) is correct. Rest of the statements are incorrect and can be corrected as
• Pollination does not give the guarantee of the promotion of post-pollination events that lead to fertilisation.
• Pollen-pistil interaction is a dynamic process involving pollen recognition followed by promotion or inhibition of the pollen.
• The pistil has the ability to recognise the pollen, whether it is of the right type (compatible) or of the wrong type (in compatible).
