Question:
Vernalisation refers to:
Vernalisation refers to:
Show Hint
Vernal = Spring. Vernalisation is the process of "making a plant ready for spring" through a cold treatment.
Updated On: May 5, 2026
- Dormancy in seeds
- Flowering induced by cold temperature
- Leaf fall in autumn
- Stem elongation
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Vernalisation is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or an artificial equivalent.
Step 2: Meaning
It ensures that reproductive development and seed production occur in the favorable spring and summer rather than the cold winter.
Step 3: Analysis
Seed dormancy is a state of suspended growth. Leaf fall is abscission. Stem elongation is often regulated by gibberellins. Vernalisation specifically links low temperatures to the transition to flowering.
Step 4: Conclusion
Therefore, the term refers to the qualitative or quantitative dependence of plants on low temperature to initiate flowering. Final Answer: (B)
