Treatment of seed at low temperature under moist conditions to break its dormancy is called -
(a)
Sclarification
(b)
Vernalization
(c)
Chelation
(d)
Stratification
Correct answer: (d) 
Solution: 
  • 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
