DENDROLOGY

Detailed explanation-1: -Seed dormancy is a state in which seeds do not germinate despite the presence of all of the necessary conditions (temperature, humidity, oxygen, and light). It is caused by hard seed coat impermeability or a lack of supply and activity of the enzymes required for germination.

Detailed explanation-2: -Seed dormancy is the state in which seed is unable to germinate, even under ideal growing conditions (Merriam-Webster).

Detailed explanation-3: -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-4: -There is a period of inactivity in the seed, during which the embryo puts its development on hold to attain physical maturation. This period of inactivity is called dormancy. When placed under proper conditions, like water, suitable temperature and air rich in oxygen, the dormant seed starts to germinate.
