Examples of layering and grafting in vegetative propagation
Answers
METHODS OF ARTIFICIAL VEGETATIVE PROPAGATION - CUTTING (BY STEM CUTTING) - DEFINITION
The common method of artificial vegetative propagation are cutting, grafting, budding and layering.
Cutting
Cutting is removing a portion of the stem and fixing it in the soil to allow the growth of roots and buds growing into shoots.
For example, rose, sugarcane, cotton etc.
BUD GRAFTING - DEFINITION
concept
Bud grafting is the one in which a bud is used instead of a twig.
For example, roses and fruits, like peaches.
TISSUE CULTURE - DEFINITION
concept
Tissue culture is an in vitro method carried on an artificial medium in which a cell, tissue, callus or explant is used to create a whole new plant.
Orchids, asparagus, chrysanthemum etc. are propagated by this method.
GRAFTING OR SCION GRAFTING - DEFINITION
concept
Grafting is joining a part of a living plant (scion) to another (stock) causing it to grow as a part of the second plant.
It may be in the form of whip grafting or cleft grafting.
CUTTING (BY ROOT) - DEFINITION
These are long pieces of roots which are used to artificially propagate now plants.
For example, lemon, orange, blackberry, boysenberry, raspberry, etc.
SIMPLE LAYERING - DEFINITION
In this layering, soft basal partly injured branch is pegged at one place.
For example, cherry, jasmine, grape vine.
TYPES OF GRAFTING - DEFINITION
The various techniques of grafting are as follows:
Tongue grafting
Wedge grafting
Side grafting
Approach grafting
Bud grafting
Micropropagation
Use of special vegetative organs
VEGETATIVE PROPAGATION BY CUTTING - DEFINITION
Vegetative reproduction takes place by the generation of a new individual by the vegetative parts like root, stem and leaf.
Cutting is the method used for vegetative propagation where the vegetative part of the stem is cut and buried in the soil.
The part which is used in cutting has the nodes which have axillary buds which help in propagation. For example, rose.
