Consider the given diagram. The phenomenon which induces the growth of plant I is
Correct answer: A. Vernalization
- A. Vernalization
- B. Seed dormancy
- C. Photoperiodism
- D. Seed germination
Explanation
The correct answer is Vernalization . Vernalization is a process in which the prolonged exposure to cold temperatures triggers the flowering of plants. This is essential for certain plants to transition from vegetative growth to flowering. The other options are related to plant growth but do not specifically describe the cold-induced flowering process:Seed dormancy refers to a period when seeds are inactive and not germinating, which is unrelated to the specific growth induction described.Photoperiodism involves the plant's response to the duration of light and dark periods, primarily affecting flowering time rather than the initial growth process.Seed germination is the process of a seed starting to grow, which is a different stage of development and not induced by cold exposure as vernalization is.

About Plant Growth Regulators
Plant growth regulators are chemical messengers that control growth, development and responses to the environment. The topic covers auxins, gibberellins, cytokinins, abscisic acid and ethylene, including cell elongation, apical dominance, tropisms, seed germination, dormancy, fruit ripening and leaf fall, with growth promoters distinguished from inhibitors.
