Question

If the peduncle shows indeterminate or indefinite growth producing flowers laterally in an acropetal order, i.e., youngest near the apex and older near the base of the inflorescence is

• A. Racemose
• B. Cymose
• C. Mixed
• D. None of the above

Answer 1

The correct option is A Racemose

The arrangement of flowers on the floral axis of the plant is known as inflorescence. The flowers can be arranged in different ways, depending upon whether the shoot apex continues to grow or convert into a flower. Two major type of inflorescence that can occur are: Racemose and Cymose.

If the peduncle shows indeterminate or indefinite growth producing flowers laterally in an acropetal order, i.e., youngest near the apex and older near the base of the inflorescence is racemose. For example: Radish, Lupin and Mustard.

Following are the types of racemose inflorescence:

• Raceme
• Panicle
• Spike
• Spikelet
• Catkin
• Spadix
• Corymb
• Umbel
• Capitulum or head
