Vegetative methods followed in our district as well as in our state to propagate various plants of economic importance.
l) Natural vegetative propagation :
In this method of vegetative propagation, a part of the plant which may be stem, root-leaf or flower gets detached from the body of the mother plant.
a) Vegetative propagation : Roots of raddish, carrot, dahlia develop adventious buds which grow into leafly shoots.
b) Vegetative propagation by stems : Stolons - Vallisneria, offsets - Eichhornia, Rhizome - Banana, Ginger Bulbs - Alliumcepa (Onion); Corn - Colacasia; Tuber - Potato.
c) Vegetative propagation by leaves : Bryophyllum.
d) Vegetative propagation by modified flowers (Bulbils) : Agave.
II) Artificial vegetative propagation :
Certain flowering plants have the capacity to develop a part of their somatic body into a new independent plant. In artificial vegetative propagation such plants are identified and special techniques are applied to obtain new independent plant.
a) Cutting (stems) : Sugarcane, Roses, Hibiscus, Citrus plants.
b) Cutting (Root) : Lemon, Tamarind.
c) Layering : Jasmine, Strawberry, Gooseberry.
d) Grafting : Rubber, apple, pear, citrus, mango, Guava.
e) Propagation by tissue culture technique : Lily, Rose, Magnolia, Fern, Banana for micro propagation, a small amount of tissue from a suitable part of the parent plant is excised and grown on a nutrient medium under aseptic conditions.
