Describe different artificial vegetative methods to produce large scale production of plan/s?
A. ) Different artificial vegetative propagation methods are cutting, layering, grafting and tissue culture methods…
2) Cutting : Some plants grow individually when a piece of parent plant having bud is cut from the existing plant. After burying in the soil the cut parts having buds grow as an individual plant after developing roots. E.g. Rose.
3) Layering : A branch of the plant with at least one node is bent towards the ground and part of it is covered with moist soil. After sometime, new roots develop from the part of the branch hurried in the soil. The branch is then cut off from the parent plant. E.g: Nerium.
4) Grafting : Two plants are joined together in such a way that two stems join and grow as a single plant. This technique is very useful in propagating improved vari¬eties of various flower and fruits. Grafting is used to obtain a plant with desirable character. E.g : Mango, citrus, apple, rose.
5) Tissue culture : In this method, few plant cells or plant tissues are placed in a growth medium with plant hormones in it and it grows into new plants. Thousands of plants can be grown in very short interval of time.
