  1. 1. MFI FOUNDATION, Inc.
  2. 2. PLANT PROPAGATION
  3. 3. Plant Propagation • The process or multiplying or increasing the number or plants of the same species and at the same time perpetuating their desirable characteristics.
  4. 4. Purpose  To retain the desirable characteristic of mother plants  To rapidly increase the number of plants.  To shorten the bearing age of plants.  To prevent the species from being lost.  To produce superior strains and disease resistant plants
  5. 5. Methods of Propagation • Sexual Propagation • Asexual Propagation
  6. 6. Sexual Propagation  The propagation or reproducing of plants from seeds.  Pollen is transferred from the anther to the stigma.  Fertilization occurs and seeds are produced
  7. 7. Advantages • In some fruit plants like papaya, this is the most popular method of propagation. • Seed propagated rootstocks are hardy and develop better root system.
  8. 8. Advantages • Viruses don’t transmit through seeds, thus mostly the seedlings are free from virus diseases. • Occurrence of polyembryony (more than one embryo in seed) in citrus and mango leads to the development of uniform seedlings as in asexual method.
  9. 9. Parts of a seed
  10. 10. Cotyledon A cotyledon is part of the embryo within the seed of a plant. Often when the seed germinates or begins to grow, the cotyledon may become the first leaves of the seedling.
  11. 11. Seed Coat The outer layer and the protective covering of a seed.
  12. 12. Radicle Radicle is the first part of a seedling to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant, and grows downward in the soil.
  13. 13. Epicotyl The epicotyl is the embryonic shoot above the cotyledons. In most plants the epicotyl will eventually develop into the leaves of the plant.
  14. 14. Hypocotyl The hypocotyl (short for "hypocotyledonous stem", meaning "below seed leaf") is the stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle (root)
  15. 15. Planting of seeds • Planting depth depends on the size of the seeds. • The larger the seed, the deeper it is planted. • Small seeds should be watered by bottom soaking.
  16. 16. Germination • Germination rate is the % that sprout. – Example: 75 out of 100 = 75% • Rates affected by…. – Seed viability. – Temperature. – Moisture. – Type of plant. – Quality of seed.
  17. 17. Germination percentage • -is an estimate of the viability of a population of seeds. The equation to calculate germination percentage is: GP = seeds germinated/total seeds x 100.
  18. 18. Example 56 is the number of seeds that is germinated 100 is the total number of seeds that is sowned
  19. 19. Asexual Propagation • In this method of propagation the plants are obtained from a vegetative portion of the mother plant instead of seeds.
  20. 20. Advantages • In some fruit plants like banana, which do not bear seeds, this is the only method of propagation. • The plants are generally true-to-type, uniform in growth, yielding capacity and fruit quality.
  21. 21. Advantages • Have short juvenile phase, thus come into bearing earlier than seedling plants. • Plants have restricted growth, thus cultural practices and harvesting are easy.
  22. 22. Methods of Asexual Propagation • There are different methods, which can be used for commercial multiplication of various fruit plants, these includes: • Cutting, • Layering, • Budding and; • Grafting. • Marcotting
  23. 23. Cutting Method • Detaching portion of the selected motherplant for the purpose of producing new plants • The three main types of cuttings are…. – Stem – Leaf – Root
  24. 24. Stem Cutting • The taking of a piece of stem to reproduce plants.
  25. 25. Leaf Cutting • The use of leaves and sections of leaves to reproduce plants. • Done from herbaceous plants. • Veins must be cut!!!
  26. 26. Root Cutting • The use of roots to reproduce plants. • Should be spaced 3 inches apart in the rooting area.
  27. 27. Layering • The process of including branch and twig to produce roots while still attached to the parent plant • The rooting of plant parts while they are still attached to the “parent” plant. • The types are…. – Air Layering. – Trench Layering. – Mound Layering.
  28. 28. Air Layering • Also called Chinese propagation. • Area of plant is girdled and surrounded by a moist growing medium that is sealed in polyethylene film.
  29. 29. Trench Layering • Mother plant is bent to the ground and buried. • Plants form at each node on covered stem.
  30. 30. Mound Layering • Rooted plant is cut off at the soil level. • As the season progresses, soil is added to cover the growing shoots. • After 1 year, the shoots are rooted and removed from the parent plant.
  31. 31. Grafting • Joining separate plant parts together so that they form a union and grow together to make one plant. • Scion – Piece of plant at the top of the graft. • Rootstock – The piece of the plant at the root or bottom of the graft.
  32. 32. Grafting • Scion & rootstock are the same size: – Wedge – Splice – Whip & tongue – Approach
  33. 33. Grafting Methods
  34. 34. Grafting Methods
  35. 35. Procedure
  36. 36. Budding A form of grafting when a bud is used. Faster or quicker than grafting. The 3 main methods are…. Patch budding. T-budding. Chip budding.
  37. 37. Marcotting
  38. 38. Tissue Culture • Must have a sterile environment. • Get the most plants in a short time. • True to parent plants.
