TYPES OF VEGETATIVE REPRODUCTION
Propagation by Runners or Stolons
Their horizontal stems grow above ground along the soil surface and
produce adventitious roots and new shoots. For example , Strawberry
Propagation by Bulb
The bulb is a shortened underground storage stems. These are enclosed with fleshy, concentric layered leaves. Bulbs produce smaller buds (lateral buds) which appear between the layers of the parent
bulb.. As the mature plants gets to the end of its life, the bud develops into smaller bulb that attaches to the baseof the parent bulb.
Propagation by Rhizome
Rhizomes are horizontal stems that grow under the ground, often sending out roots
and shoots from their nodes. If a rhizome is separated into pieces, each pieces may be able to give rise to a new
plant.
Propagation by Tuber
The white potato and sweet potato are
enlarged, shortened stems that are specialized for storing reserve food. These underground stems grow horizontally outwards in the soil
and each tuber is irregular in shape.
Propagation by Cutting
Cutting involves removing a piece of the parent plant - stem, root or leaf,
and planting it in a suitable medium.
Propagation by Layering
This is the method of vegetative propagation in which branch of a parent plant is bent to the ground or water until it can be covered by soil and new root system appears. The tip of the
shoot remains above ground New roots and eventually a new plant will grow .These plants can then be separated.
Propagation by Grafting
Two plants are used to develop a new plant with combined traits from the
parent plants. In grafting one plant attached on to body of the other plant.
Tissue Culture
is a method of biological research in
which the fragments of tissue from an animal or plant are
transferred to an artificial environment in which they can continue to survive and function.
