A) scarification
B) stratification
C) impaction
D) vernalization
Correct Answer: B
Solution :
In many species, dormancy due to chilling requirement can be overcome by heating the seeds in moist medium at low temperature (5-10°G) for sufficient period of time. This process is known as stratification. Artificially stratification is done by alternating the layer of seeds with layer of peat moss (Sphagnum) on some other suitable material and keeping them at low temperature.
