Question:
Vernalization increases the resistance of plants for diseases caused by ___________.
Vernalization increases the resistance of plants for diseases caused by ___________.
Show Hint
Vernalization improves plant hardiness and resistance, especially against fungal infections.
Updated On: Feb 9, 2026
- Bacteria
- Viroids
- Viruses
- Fungi
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding vernalization.
Vernalization is the process of exposing plants to low temperatures to induce early flowering and improve overall plant vigor.
Step 2: Effect on disease resistance.
Vernalization not only affects flowering but also increases resistance of plants to certain diseases, particularly those caused by fungal pathogens.
Step 3: Analysis of options.
(A) Bacteria: Incorrect — vernalization does not specifically enhance resistance to bacterial diseases.
(B) Viroids: Incorrect — viroid resistance is not linked to vernalization.
(C) Viruses: Incorrect — viral resistance is genetically controlled.
(D) Fungi: Correct — vernalization increases resistance against fungal diseases.
Step 4: Conclusion.
Vernalization increases resistance of plants to diseases caused by fungi.
Vernalization is the process of exposing plants to low temperatures to induce early flowering and improve overall plant vigor.
