Seed Dormancy in Medicinal Plants
- Definition: delayed germination of the seed
- Types of seed dormancy:
- Seed coat dormancy
- Embryo dormancy
- Causes of seed coat dormancy:
- Impermeability of seed coat to water
- Impermeability of seed coat to oxygen
- Resistance of seed coat to expansion
- Methods to overcome seed coat dormancy:
- Soaking seeds with H2SO4
- Causes of embryo dormancy:
- Undeveloped embryo
- Failure of embryo to emerge from resting conditions
- Methods to overcome embryo dormancy:
- Stimulating the embryo by heating or cooling at 0-10°C
