2. INTRODUCTION
•Artificial vegetative propagation is the
deliberate production of new plants
from parts of old plants by
humans. This can be done by following
three methods:
1. Layering
2. Cutting
3. Grafting

3. Layering...
• In this method, a stem or a branch is
bent to the ground.
•A small part of the stem is buried in soil
so that roots develop there.
•Examples are grapes, climbing roses,
jasmine,etc.

4. LAYERING

5. Cutting...
• In this method, a small part of a stem,
leaf or root is cut and planted in soil. This
is called a cutting.
•It develops roots and forms a new plant.
•Examples are rose, hibiscus and
bougainvillea, etc.

6. CUTTING

7. Grafting...
•This method combines the desirable characteristics
of two varieties of a plant.
•The stem of a plant is cut off such that its roots are
still in the soil.This plant is called the stock.
•A stem cutting from another healthy plant named
the scion is placed over the stock.
•The stock and scion are tied together and the stock
provides the scion with water and minerals .
•The resulting plant has the hardiness of the stock
but the desirable fruits or flowers of the scion.
