Current Question (ID: 12305)

Question:

Select incorrect statement with respect to racemose inflorescence

Options:

1. The main axis continues to grow
2. Peduncle bears flowers in basipetal/centrifugal manner
3. The main axis is not terminated into flower
4. It is an indeterminate inflorescence

Solution:

The statement "Peduncle bears flowers in basipetal/centrifugal manner" is incorrect. In racemose inflorescence, the main axis (peduncle) bears flowers in an acropetal manner, which means the lower flowers are older and matured earlier than the upper flowers. The flowers are arranged in an indeterminate manner, with the main axis continuing to grow and producing new flowers at the apex while older flowers are at the base. Racemose inflorescence is characterized by an unbranched main axis that does not terminate into a flower, and new flowers are produced laterally along the main axis.
