Question

Inhibitory substances in dormant seeds cannot be removed by subjecting seeds to:

• A. Gibberellic acid
• B. Nitrate
• C. Ascorbic acid
• D. Chilling conditions

Answer 1

The correct option is C Ascorbic acid

Seed dormancy is the lack of seed germination.

Chemical inhibitors such as abscisic acid and phenolic acids present in the seeds prevent germination.

Inhibitory substances in dormant seeds can be removed by subjecting seeds to:

• chilling conditions.
• application of certain chemicals like gibberellic acid, potassium nitrate and thiourea.

Hence, the answer is option c.
