Promotion of flowering by cold treatment given to imbibed seeds or young plants is known as:
Correct answer: D. Vernalization
- A. Parthenocarpy
- B. Parthenogenesis
- C. Apomixis
- D. Vernalization
Explanation
Vernalization is a biological process in plants where exposure to a period of low temperatures induces or accelerates flowering. This cold treatment is often required for certain plants to transition from the vegetative phase to the reproductive phase. Vernalization helps ensure that flowering occurs during the appropriate season, usually spring, and is crucial for the successful reproduction of many plant species.
