| This course covers the structure and characteristics of forest tree seeds, as well as principles of seed supply, harvesting, and storage. Seed physiology, germination requirements, and methods for determining seed viability are examined in detail; additionally, germination barriers and the techniques used to overcome them (mechanical, chemical, and stratification treatments) are evaluated. Pre-sowing treatments applied to seeds are also addressed within a comprehensive framework. |
