Question

Vernalization is defined as

• A. All changes that an organism goes through during its life cycle.
• B. Flowering that is either quantitatively or qualitatively dependent on the exposure to low temperature.
• C. Flowering induced only when a plant is exposed to certain duration of photoperiod.
• D. Presence of different kinds of structure in response to environment or phases of life.

Answer 1

Answer: (B)

Vernalization is the induction of a plant's flowering process by exposure to the prolonged cold in winter or by an artificial equipment. After vernalization, plants acquire the ability to flower, but they may require additional seasonal cues or weeks of growth before they actually flower.
