Regeneration of new plant from a part of the Vegetative Organ is called Vegetative Reproduction or Vegetative Propagation.
Type of Vegetative Propagation
- Natural Vegetative Propagation
- Artificial vegetative Propagation
Natural Vegetative Propagation
In natural vegetative propagation, a portion is detached from the body of mother plant and grows into a new independent plant under suitable condition.
Type of Natural Vegetative Propagation
- Rhizome – Rhizomes are thick prostrate, underground stem which grow horizontally beneath the soil surface.
- Example – Ginger (Zingiber officinale), Turmeric (Curcuma domestica), Canna (Canna indica)
- Tuber – Tuber are modified underground stems, developed as a result of accumulation of reserve food material at the tip of branches as in potato.
- Example – Potato (Solanum tuberosum)
- Bulb – It refer to a short and thicken underground stem axis represented by a convex or likely conical disc.
- Example – Onion (Allium cepa), tulip, daffodile, lily, Narcissus
- Runner – Runner is a cylinder, prostrate, sub aerial stem that creeps horizontally on the surface of the soil.
- Example – Doob grass (cynodon dactylon), Wood-sorrel (Oxalis)
- Offset – Offset is a short, stout, thick and slender condensed runner that originate in the axil of a leaf and elongate only to a limited extent.
- Example – water Hyacinth (Eichhorina)
- Sucker – A Sucker is a sub aerial branch that arises from the basal underground portion of the main stem.
- Example – Mint (Mentha), Chrysanthemum
- Stolon – Like Runner, it is also a slender lateral branch originating from the base of the system. But at first it grows obliquely upward and then it went down to the ground.
- Example – Strawberry (Fragaria)
- Roots – Roots of some woody plants can produce buds, which can grow into new plants.
- Examples – Sweet potato, Asparagus, dahlia, Murraya koenigii, Dalbergia sissoo, Albizza lebbek
- Leaves – In some plants Foliar buds produced on the leaf margin, which grow into new plant.
- Examples – Bryophyllum, kalanchoe
- Bulbils – in some flowers lower part of the inflorescence are modified into small multicellular structures known as bulbils, they fall on the ground and grow into a new plant.
- Examples – Aloe (Agave sisalana), Yam (Dioscorea bulbifera)
Artificial Vegetative Propagation
In Artificial vegetative propagation, a portion is detached from the body of the mother plant and is then grown independently. It is usually done for quick production of new plants and retaining the qualities of the mother plant.
Types of Artificial Vegetative Propagation
- Cutting – This is the most common method of vegetative propagation, in this method a portion of root, stem or leaf known as cutting is taken and rooted in the soil which develop into a new plant.
- Examples –Sugarcane, roses, grapes, tapioca, Coleus, Bougainvillea
- Layering – In layering roots are induced on branches still attached to the parent plant, it is commonly practiced in many to tree and ornamental plants whose cutting do not easily root.
- Examples – Pomegranate, orange, guava, litchi, jasmine, apple
- Grafting – The process of joining together parts of two different plants in such a manner that they lived as one plant is called grafting. Grafting of plant is widely used Horticultural practice of multiplying the desired genotypes of species.
- Examples – Roses, Peaches
|Importance Of Vegetative Propagation||Limitations Of Vegetative Propagation|
|Vegetative Propagation is a rapid, easier and a less expensive method of multiplying plants, it also make possible the propagation of plants life banana, seedless grapes, oranges. Plant raised through vegetative propagation are the exact genetic copies of the parents having the same character also we can say it clone.||Vegetative Propagation requires technical expertise. Since, vegetatively propagated plant do not have tap roots, suchplants are easily uprooted in Storms. Vegetative propagation does not involve in meiosis and fusion of gametes, hence this process is not helpful in developing new varieties.|
