Presentation Transcript

  1. House PlantPropagation

  2. Asexual Methods • Layering • Air layering • Offsets • Plantlets • Cuttings • Stem • Leaf • Cane • Division

  3. Cuttings • Most commonly used asexual propagation method • Pieces of vegetative material • Adventitious rooting • Seminal roots • Non-seminal roots • Stem, leaf, root • Herbaceous and woody species

  4. Stem Cuttings contain ≥ one bud • Terminal (tip) cuttings • Non-terminal cuttings • ≈ 3’’ long with leaves • Herbaceous • Woody plants • Softwood • Semi-softwood • Hardwood

  5. Stem Cuttings

  6. Softwood cuttings

  7. Leaf Cuttings • Herbaceous cuttings • Full • Partial • Leaf-vein • Leaf-bud

  8. More Leaf Cuttings

  9. Cane cuttings

  10. Divisions • Mother plant divided into smaller sections

  11. Layering Induced Layering • Simple layering • Wound stem, peg into soil

  12. Air layering

  13. Offsets

  14. Plantlets

  15. Rooting Hormones • Auxins occur naturally in plants • Promote cell division, cell expansion, rooting • Synthetic auxins available • Naphthaleneacetic acid (NAA) and indole 3-butyric acid (IBA) • solutions or powders; often used in combination • Rootone, Hormodin, Hormex, Dip ‘N Grow

  16. Rooting Hormones Why use? • Promote rooting of cuttings • Increase rooting percentage of many hard-to-root plants • May shorten rooting time • May improve root quality and quantity • Cuttings of most plants will benefit from their use
