Question

Cauliflory is
A. Production of new plants from cauline buds
B. Formation of flowers from the old stem
C. Development of flowers on young branches
D. Clustering of flowers

Answer 1

Cauliflory is a botanical term. It refers to plants that flower and fruit from their main stems or woody trunks rather than from new growth and shoots. This allows trees to pollinate or have their seeds dispersed by animals that cannot climb or fly.

Complete answer:
Option A- Production of new plants from cauline buds
Some adventitious buds arise from extra-axillary positions on the stem, these are known as cauline buds. Buds are small, lateral and terminal protuberance on the stem of a vascular plant. It develops into a flower, leaf, or shoot.
Option B- Formation of flowers from the old stem
The formation of flowers from the old stem is known as Cauliflory. The production of flowers and fruits takes place directly from the branches or trunks of the woody or tropical plants.

Option C- Development of flowers on young branches

Important structures in plant development are buds, shoots, roots, leaves, and flowers. Plants produce tissues and structures throughout their life from meristems that are located at the tips of organs, or between mature tissues. Thus, a living plant constantly has embryonic tissues.
Option D- Clustering of flowers
A group or cluster of flowers arranged on a stem is known as an inflorescence. It is composed of the main branch or a complicated arrangement of branches. Morphologically, it is known as the modified part of the shoot of seed plants where flowers are formed.

So, the correct answer is option B- 'formation of flowers from old stem'.

Note: The concept of cauliflory includes that of ramiflory. Ramiflory, in plant biology, is the production of fruit and flowers on the woody branches of a plant, formed in a previous season. The corresponding condition for the trunk of the plant is known as cauliflory.
