  •  The part of plant which is used in vegetative propagation is called propaguale. It is of following types
    1. Natural vegetative propagation
    2. Atificial vegetative propagation
    Natural Vegetative Propagation
    When daughter bodies are produced from propatuale without involvement of any agent is called natural vegetative propagation.
    e.g Eyes in potato, bulb of onion, shizome of ginger, nodes of sugarcane, leaf in bryophyllum.
    Artificial Vegetative propagation
    When daughter plants are produced from propaguale by the involvement of agents is called artificial vegetative propagation.

  • Plant tisue culture is a vegetative method ( micropropagation technique) which we use to produce resistanat variety plants, plants with more yield and sustainability. it can be vegetatively propagated from the shoot,root and any part of the plant which we name as the explant. The explant must be sterilised before taken for tissue culture and the procedure and the laboratory area should be completely sterile.shoot tip culture and nodal culture are made to form callus(undifferentiated mass of cells) which then grows into a copact planlet when suspended in suitable medium (liquid or solid). After attaining proper growth, the plantlet is alowed to grow in primary hardening and then transferred for secondary hardening which is distributed to the farmers and most importantly it should be devoid of infection.

    Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues or organs under sterile conditions on a nutrient culture medium of known composition. Plant tissue culture is widely used to produce clones of a plant in a method known as micropropagation. Different techniques in plant tissue culture may offer certain advantages over traditional methods of propagation, including:

    • The production of exact copies of plants that produce particularly good flowers, fruits, or have other desirable traits.
    • To quickly produce mature plants.
    • The production of multiples of plants in the absence of seeds or necessary pollinators to produce seeds.
    • The regeneration of whole plants from plant cells that have been genetically modified.
    • The production of plants in sterile containers that allows them to be moved with greatly reduced chances of transmitting diseases, pests, and pathogens.
    • The production of plants from seeds that otherwise have very low chances of germinating and growing, i.e.: orchids and Nepenthes.
    • To clear particular plants of viral and other infections and to quickly multiply these plants as 'cleaned stock' for horticulture and agriculture.
