Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of seed dormancy and treatments.
Step 2: Detailed Explanation:
Exogenous dormancy is caused by seed coat (physical dormancy).
Scarification is the treatment to overcome exogenous dormancy.
It involves mechanically or chemically breaking the seed coat.
Stratification (A): Treatment for physiological dormancy.
Vernalization (C): Cold treatment for flowering.
Chemical treatment (D): Can be used for scarification but the term is scarification.
Thus, the correct answer is scarification.
Step 3: Final Answer:
Thus, scarification is the treatment for exogenous dormancy, which corresponds to option (B).
