Solution

Physical dormancy, also known as seed coat dormancy or hard seed coat dormancy, refers to the impermeability of the seed coat, which hinders water absorption and gas exchange, preventing germination. Scarification is a common method used to break or weaken the hard seed coat, allowing water and gases to penetrate the seed.
