Vegetative Propagation: Artificial

Name of MethodWhat You Do: diagram in sequence?
Leaf Cutting Cut leaf (blade plus petiole) from plant
Blade produces IAA (auxin)
IAA transported down petiole to cut end
Callus forms as IAA concentration builds
Adventitious roots form as IAA concentration continues to increase
Root tips produce CK (cytokinins)
CK transported along root toward callus
Shoot forms on callus
Rooting accelerated by applying synthetic-IAA powder to cut end of petiole at start!
Stem Cutting Cut shoot (stem plus a few leaves) from plant
Blades produce IAA (auxin)
IAA transported down stem to cut end
Callus forms as IAA concentration builds
Adventitious roots form as IAA concentration continues to increase
Much faster with multiple sources of IAA!
Rooting can be accelerated by synthetic-IAA powder
Tip Layering Bend stem down to soil
Wound bark at point of soil contact
Dust wound with synthetic IAA powder
Anchor with croquet wickets or similar
Bury treated wound in moist soil
Wait for roots to form
Separate plant from "original"
Air Layering Find pencil-sized branch to layer
Wound bark at point of interest
Dust wound with synthetic IAA powder
Wrap with wet unmilled sphagnum moss
Wrap with white or silver plastic film with twist-ties
Keep moist as you wait for roots to form
Separate plant from "original"
