Endogenous dormancy is the most common form of dormancy found in plants. It is caused by factors within the embryo. Dormancy is relieved in this type of dormancy by a variety of means depending on the species.
Treatments include a requirement for dry storage, light or darkness, and warm or chilling stratification.
Types of endogenous dormancy are listed in the table to the right.
Factors within the embryo inhibit germination
Requires brief chilling stratification or a period of dry storage.
Embryo needs chilling stratification, but will grow normally if excised from the seed coat.
Embryo needs chilling stratification, but embryo will not grow normally if excised.
The embryo is not fully developed at the time the seed sheds from the plant.
Combination of an underdeveloped embryo and physiological dormancy.
