Detailed explanation-1: -Dormancy is defined as the temporary inability of a viable seed to germinate under favorable environmental conditions (Simpson, 1990). Dormancy helps the seed to survive adverse environmental conditions and at the same time helps in seed dispersal (Snape et al., 2001).

Detailed explanation-2: -Seed dormancy has been defined as the incapacity of a viable seed to germinate under favorable conditions (Bewley, 1997; Finch-Savage and Leubner–Metzger, 2006).

Detailed explanation-3: -dormancy, state of reduced metabolic activity adopted by many organisms under conditions of environmental stress or, often, as in winter, when such stressful conditions are likely to appear.

Detailed explanation-4: -Dormancy refers to a period of time when the organism physically stops growing; this is typically done to conserve energy during the colder months of the year or to protect itself from adverse environmental conditions.

Detailed explanation-5: -Abiotic factors such as drought, light, salinity, seed burial depth, soil pH, and temperature as well as disturbance events such as a fire, flooding or tillage can play an important role in initiating or inhibiting seed germination [3–4].
