Question

Given below are two statements:
Statement (I): The non deep type is the most common primary dormancy
Statement (II): In this type of dormancy species require light or darkness to germinate or chilling stratification
In light of the above statements, choose the most appropriate answer from the options given below

• A. Both Statement (I) and Statement (II) are true.
• B. Both Statement (I) and Statement (II) are false.
• C. Statement (I) is true but Statement (II) is false.
• D. Statement (I) is false but Statement (II) is true.

Hint:

Seed dormancy ensures germination at the right time.
Non-deep dormancy: Common, embryo is developed. Broken by conditions like light, after-ripening (dry storage), or alternating temperatures.
Deep dormancy: Requires more specific, often prolonged treatments like chilling stratification (moist cold). Statement II incorrectly groups chilling stratification with common requirements for non-deep dormancy.

Answer 1

The Correct Option is C

Step 1: Non-deep physiological dormancy is recognised as the most common form of primary seed dormancy, so Statement (I) is correct.
Step 2: Non-deep dormancy is usually broken by light or dark cues or simple after-ripening, not by chilling stratification.
Step 3: Chilling stratification is characteristic of deep dormancy, not the non-deep type, so Statement (II) is incorrect.
Step 4: The correct answer is Statement (I) is true but Statement (II) is false.
