Vegetative Reproduction
Propagation by Rhizome:
- Rhizomes are segmented, fleshy underground stems. They serve as storage and
reproductive structures.
- Examples: canna lilies, bearded iris, ginger and bamboo.
-
Propagation by Bulb:
- Examples: Tulips, Daffodils, Lilies and onions.
- Bulbs are shortened underground storage structures. They are stems that 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 lateral bud developsinto a smaller bulb that attaches to the base of the parent bulb. The new bulb can be separated and planted.
-
Propagation by Cutting:
- Cutting involves removing a piece of the parent plant - stem, root or leaf,and planting it in a suitable medium.(such as soil or water) until a new root system appears. At first rootsare produced and then the shoot with the leaves.
-
By Runners or Stolons:
- Their horizontal stems grow above ground along the soil surface and
produce adventitious roots and new shoots.
-
- Example: strawberries, bermudagrass, peppermint and spidergrass.
Propagation by Tuber:
- Stem tubers have eyes or nodes on them that can produce new shoots. A great example is the potato tuber. The eyes often begin to sprout into new shoots when left for some time. Each shoot that appears on the tuber can be cut and planted to produce a new plant.
-
- There are two categories of tubers: stem tubers and root tubers. As their names suggest stem tubers are the swollen parts of the stem buried in the soil. Root tubers are the swollen roots. Both are storage systems of the plant.
Propagation by Grafting:
- Grafting is propagation by combining a scion of one plant and connecting it to the stock of another. This form of propagation is primarily used with woody plants. There are many forms of grafts that can be done for many purposes.
-
- Example: the cleft, tongue, and saddle graft.
-
Tissue Culture :
- 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. Cells in a culture may multiply; change size, form, or function, exhibit specialized activity, or interact with other cells.
- Example: meristematic cells in
plants.
