Question

Vernalization stimulates flowering in

• A. zamikand
• B. turmeric
• C. carrot
• D. ginger

Answer 1

The Correct Option is C

To understand the concept of vernalization and its effect on stimulating flowering, we need to delve into the biology of certain plants.

Vernalization is a physiological process in which the flowering process is accelerated by a period of exposure to cold temperatures. This is particularly significant in temperate plants, which require a prolonged exposure to the cold season to initiate blooming once they are exposed to warmer conditions.

Among the given options:

• Zamikand: This plant, often known as elephant foot yam, doesn't require vernalization for flowering.
• Turmeric: Typically grown as a perennial in warm climates, turmeric does not depend on vernalization.
• Ginger: Like turmeric, ginger is a tropical plant that does not undergo vernalization.
• Carrot: As a biennial plant, carrot undergoes vernalization. In its first year, it usually grows leaves and stores energy in its root. It requires cold exposure over the winter to flower in the subsequent spring or summer. Therefore, vernalization stimulates flowering in carrots.

Based on this explanation, the correct answer is carrot, as vernalization is crucial for converting its vegetative stage to the flowering stage during its biennial lifecycle. This is a critical process for certain crops and is also artificially employed in agriculture to ensure better yield and seasonal flowering in some species.
