Question

Vernalization is a phenomenon which concerns

• A. Low temperature requirement for flowering in plants
• B. Migration of birds from their winter homes to summer habitats
• C. Immunization of infants against the common infectious diseases
• D. Entering of cold blooded animals into an inactive state in winter

Answer 1

The correct option is A Low temperature requirement for flowering in plants

Vernalization is the acquisition of a plant's ability to flower in the spring by exposure to the prolonged cold of winter, or by an artificial equivalent. Many plants grown in temperate climates require vernalization and must experience a period of low winter temperature to initiate or accelerate the flowering process. This ensures that reproductive development and seed production occurs in spring and summer, rather than in autumn.
