VISUAL PRESENTATION OF EXTENSION MATERIAL ON TREE SEED
  2. 2. The biodiversity of trees in Ethiopia, is the foundation of our seed sources. Ethiopia is rich in different varieties of vegetation. The various types of forests in Ethiopia provide an extraordinary foundation for seed sources. We have a great opportunity to preserve and improve the quality of this natural wealth in the future.
  3. 3. Uses of the forests Main function Timber Poles Wood for pulp and particle board Firewood
  4. 4. Uses of the forests Conservation functions As a source of clean Water To prevent landslides and flooding To reduce impact of pollution To protect the biodiverstiy
  5. 5. Uses of the forests Other functions As a source of medicines Fodder for domestic animals Ecotourism Natural Honey Natural rubber Fruits Recreation
  6. 6. Selecting good seed sources, results in high quality seeds The quality of a tree depends also up on the quality of the seed and from where it originates. High quality seed results in high quality trees. The choice of seed is the first important step in tree planting. Pay attention to the age and the shape of the trees when selecting the seed sources.
  7. 7. Selecting seed sources
  8. 8. Genetic Characteristics Similar to animals the genetic characterstics of trees provide the variation by careful selection of the source of seed. It is possible to obtain a new generation of trees of higher quality.
  9. 9. What we see is a result of genetic traits and environmental factors: Genetic Traits Wind Rain Altitude Temprature Soil Light
  10. 10. Growth factors Environmental factors A. Force of the wind B. Stress on growth C. Poor drainage A A AA AB BB B B C Genetic factors
  11. 11. There is life inside the seed, give it the appropriate protection Like all living beings, seed needs protection. Quality seed must be treated well: give it enough air, shelter from the sun and protect it against rain and humidity. By treating the seed well the quality is maintained.
  12. 12. Protection of seed Quality of seed is seriously affected by rain and heat Seed must always be kept in dry, well ventilated places Examples of appropriate places for temporary storage
  13. 13. Seed Procurement Seed collection Storage Drying Temporary storage
  14. 14. Labelling Species; seed source; data of collection; owner of the seed source; collector. Species: ............................Seed Source: .......................Date of Collection: ...............Owner of The Seed Source:............................. ..................Collector: ........................... Accurate data on the seed bag and inside the seed bag show the quality of the seed inside. Seed documentation is important throughout the whole seed procurement “chain”, from collection to distribution.
  15. 15. Matching planting site to seed collection site is important To ensure optimal growth of trees, the growth conditions of the planting site should match the growth conditions at the seed collection site - altitude, temperature, rainfall and soil characteristics.
  16. 16. Suitability of the land to be planted Most trees have specific agro- ecological requirements for optimal growth.
  17. 17. Pre-treatment of seed
  18. 18. Planting techniques 20-40 cm deep hole for seedling from a container 20-40cm hole for bare root seedlings 60cm hole for fruit trees
  19. 19. Spacing in the planting A spacing of 3X3 m A triangular Planting orientation Planting in groups A spacing of 3X2 m
  20. 20. Replacement of seedlings Survival is more than 80% Survival is more than 80%, and there are big bare spots with no survivng trees Survival is less than 80% This is not necessary when: It must be done when:
  21. 21. From seed collection to tree planting operation Collection Planting Sowing Pre-treatment Storage Drying Temporary storage Ethiopia is rich in different varieties of vegetation. The various types of forests in Ethiopia provide an extraordinary foundation for seed sources. We have a great opportunity to preserve and improve the quality of this natural wealth in the future.
  22. 22. The quality of the forests in the future depends up on the quality of seedling planted today Quality seed is obtained through appropriate seed procurement, including choice of seed sources, seed collection, seed shortage, seed distribution and seed documentation. Appropriate seed procurement leads to better forests the future.
