how are runners used in cloning plants
a lateral stem grows away from the parent plant and root develop where the runner touches the ground and a new plant develops
how are stem tubers used in cloning plants
the tip of an underground stem becomes swollen with stored food to form a tuber. Buds the develop to produce new shoots
how is a cutting of a plant taken
shorter sections of stems are taken and planted
rootling hormones are applied to the base of a cutting
