Vegetative Propagation: Natural

Name of MethodHow it works: diagram?Example Plant(s)
Epiphyllous Buds Cytokinins in leaf edges cause formation of shoot
Auxins from shoot tip cause formation of roots
Plantlets fall to soil as separate plant
Bryophyllum daigremontianum (maternity plant, mother of thousands), Piggy back plant
Scaly Bulb Bulb made of leaf bases attached to basal plate, roots are adventitious
lateral buds between leaf layers at basal plate form bulbils
in years where one bulb planted a clone of competitors develops
Onion, Tulip, Daffodil
Corm Like scaly bulb without layers, so just basal plate
lateral buds on stem develop into cormels
in years where one corm planted a clone of competitors develops
Crocus, Gladiolus
Tuber at end of Rhizome Late Summer leafless underground stems penetrate soil (rhizomes)
Early Fall: tips of rhizomes swell into tuber
Tuber has many lateral buds (eyes) that grow into separate plants
Potato, Helianthus tuberosus
Stolons with Crowns Plant produces leafless branch (stolon)
Crown develops at end of stolon
Weights tip to ground, roots, establishes clone
Spider plant, Strawberry
Tip Layer Normal Leafy Shoot Elongates
Buries tip in soil
Adventitious Roots form
Shoot develops in Spring
Black Raspberry, Forsythia
Root Sprouts Roots of plant penetrate soil
Some reach near soil surface
Cytokinins accumulate and shoot forms
Red Raspberry, Rose, Most Shrubs
