Vegetataive Propagation By: Chia-ho Lin

What is Vegetation Propagation ?

  • kind of asexual reproduction.
  • The process could occur naturally or by human "help".
  • Creates and identical plant as the parent cell.
  • Could grow by budding or producing roots in the soil by one part of the parent cell. (Ex: Kalanchoe Buds)

Natural

Stem

  • Runners; stems that grow horizontally above the ground.
  • Have nodes where Buds grow.
  • Grows out from the base of the main stem.
Strawberry Plant

Roots

  • New daughter plants grow out of tubers.
  • Tubers: swollen modified roots.
  • Buds first develop at the base of the stem and grows into a new plant.

Leaves

  • Some Certain plants could grow from detached leaves (EX: House leek)
  • Other plants grow plantlets (small plants) on the edge of their leaves.

Bulb

  • Bulbs are a kind of plant that contains underground stems.
  • Leaves attached to the stem contain many stored food.
  • Inside a bulb there is anĀ apical bud (produces leaves &flowers) and many lateral buds (new shoots).
  • New bulbs form as the plant develops or grows.

Artificial

Cuttings

  • Cuttings: Part of plant that is cut off from parent plant.
  • Farmers usually use shoots with leaves on them.
  • The Cutting is done at a certain angle.
  • Growth promoters are used to able the roots to grow faster.
Cutting Process

Grafting

  • Grafting: Two different traits of two parent plants are placed together, develops a new plant.
  • Combines or attaches the scion (upper part of plant above soil) and the stock (root part).
Cleft Grafting

Layering

  • Layering: Shoot of parent plant is bent until it could be covered by soil.
  • Tip of the shoot remains above the soil.
  • New plant would grow and later would separate from the parent plant (by humans).
