Causes of seed dormancy and how to deal with it
Seed dormancy is the phenomenon that the seed still does not germinate under suitable germination conditions. According to the time of seed dormancy, it can be divided into primary dormancy (had dormant phenomenon at the time of harvest) and secondary dormancy (non-dormant or unsuspended seeds have bad environment due to high humidity, low oxygen, high carbon dioxide, lack of light, etc. Conditions induced by dormancy).
The reasons for seed dormancy fall into two broad categories: The first is caused by factors of the embryo itself, including incomplete embryo development, physiological immaturity, lack of essential hormones, or the presence of substances that inhibit germination. This kind of dormancy can be eliminated by low temperature stratification, temperature change treatment, drying, hormone treatment, and other methods. The second category is caused by the restriction of seed shells (seed coats, peels, etc.), including mechanical barriers, water impermeability, gas impermeability, and the presence of substances that inhibit germination in the seed shells. This dormancy can physically or chemically destroy seed coats or remove seed shells to relieve dormancy.
