In plant morphology, the arrangement of flowers on the floral axis (inflorescence) or leaves on a stem follows specific patterns. One of the most common patterns is the 'Acropetal Order'.
Acropetal growth is indefinite; the main axis continues to grow.
It is a defining characteristic of Racemose inflorescence.
Examples include mustard, radish, and snapdragon plants.
Acropetal order refers to the arrangement where the oldest parts are at the base, and the youngest (newest) parts are at the top (apex).
In the context of flowers (Racemose inflorescence):
The exact opposite of acropetal is the Basipetal Order (seen in Cymose inflorescence). In basipetal succession, the oldest flower is at the top (apex) which stops the growth, and the younger flowers grow below it towards the base.
Acropetal means oldest at the base and youngest at the top. Basipetal means oldest at the top and youngest at the base.
