Question

Treatment of seed at low temperature under moist conditions to break its dormancy is called -

• A. Sclarification
• B. Vernalization
• C. Chelation
• D. Stratification

Answer 1

Answer: (D)

Stratification

• Stratification involves the treatment of seed at low temperature(5−10 C)

under sufficiently moist conditions to break its dormancy and to induce germination.

• Scarification involves any damage or breakage of seed coat by physical methods (eg, use of a scalpel, wooden hammer, etc) or chemical methods (use of mild acids) to break seed dormancy.
• Vernalization and Chelation is the chill treatment Df plant in its early stages of life history to stimulate or induce early flowering

So, the correct answer is 'Stratification'.
