Question

Treatment of seeds at low temperature under moist conditions for breaking their dormancy is ?

• A. Vernalisation
• B. Chelation
• C. Stratification
• D. Scarification

Answer 1

Answer: (C)

Stratification

a) Vernalization is the induction of a plant's flowering process by exposure to t prolonged low temperature.

b) Chelation involves the formation of two or more separate coordinate bonds between a polydentate ligand and a single central atom.

c) Stratification involves the treatment of seed at low temperature (5 - 10${}^o$ C) under sufficiently moist conditions to break its dormancy and to induce germination.

d) Scarification is the process of weakening seed coat mechanically, thermally or chemically to encourage germination.

So, the correct answer is C.
