Difference between dormancy and breaking of dormancy.

Expert Answer:

Mature seeds of some species are incapable of germinating, even under ideal conditions of temperature and moisture, unless they receive certain environmental stimuli. Such seeds are said to be dormant and their state of inactiveness is called dormancy.

The seeds of many species do not germinate immediately after exposure to conditions generally favourable for plant growth but require a breaking of dormancy, which may be associated with a change in the seed coats or with the state of the embryo itself. Seeds lose dormancy after the seed coat is removed or sufficiently damaged to allow water to enter. Germination in such cases depends upon rotting or abrasion of the seed coat in the soil.
