Question

Consider the following statements:
Assertion (A): Seed dormancy may be caused by hard seed coats in Fabaceae
Reason (R): Such type of seed dormancy can be broken by stratification

Hint:

Distinguish between physical and physiological dormancy.
Stratification = cold/wet treatment for physiological dormancy.
Physical dormancy → scarification.

Answer 1

1. Hard seed coats in Fabaceae cause physical dormancy → (A) true.
2. Stratification is a treatment for physiological dormancy, not physical dormancy → (R) true but not correct explanation.
3. Hence correct answer is (2) Both (A) and (R) are true, (R) is not the correct explanation of (A).
