Bryophyllum delagoensis
Cytokinins accumulate in notches stimulate shoot development

Onion, Tulip, Daffodil
Scales are leaf bases.
Basal plate is stem.
Roots are adventitious.
Lateral buds in axis make bulbils.

Scaly Bulbs
In garlic bulbs, the lateral buds become bulbils called “cloves” of garlic.

Tuber at end of rhizome (underground stem)
Tuber swells as a storage organ.The apical bud and lateral buds are “eyes.”A piece of potato with an eye can be treated almost like a seed.
Potato, Helianthus tuberosus

Stolons: Spider Plant and Strawberry
Leafless overground branch develops crown which arches to soil, roots, and becomes independent.

Tip Layer
Leafy shoot tip arches to soil, takes root, and becomes independent plant.
Bramble describes this behavior.

Root sprouts Red Raspberry and Rose, many others!
Roots growing from original plant near soil surface, accumulate cytokinins, make sprout.

2. Wound bark on lower side
What if the plant you want to clone is a special maple tree that turns wonderful combinations of green, yellow, orange, and red in the fall. The lowest branch is many feet above the soil making a tip-layer impossible. Leaf and stem cuttings fail but you think a tip-layer might work if only the tree were not so tall. How do you solve this dilemma?
If the cutting is Mohammad, and you cannot bring Mohammad to the mountain, you should…
…bring the mountain to Mohammad! Air Layer!
We will work this example on the whiteboard together in class!
