Vegetative propagation is a form of asexual
reproduction of a plant. The new plant is genetically
identical to the parent.
Vegetative propagation is the process of
multiplication in which a portion of fragment of
the plant body functions as propagates and
develops into a new individual.
1. Propagation by roots
2. Propagation by stem
3. Propagation by leaves
These structures are called as vegetative
propagates or propagules.
1.PROPAGATION BY ROOTS:-
The roots of some plants develop adventitious
buds on them e.g., Dalbergia sissoo (Shisham),
Guava, poplars, Albizzia lebbek, Murraya, etc.
Some tuberous adventitious roots besides
possessing adventitious buds also contain
sufficient quantities of, food, e.g., Dahlia and
TUNICATED BULB NON-TUNICATED BULB
1. Form concentric rings
around growth point.
2. Have protected tunic layer
of dried ring layers.
3. Not easily damaged
1.Do not form concentric
rings around growth point.
2.Not protected by tunic
layer of dried ring layers.
3. Damaged during digging.
3.PROPAGATION BY LEAVES:-
Some plants produce adventitious buds
on their leaves.
These buds usually remain dormant,
when the leaf is attached with plant.
However, the leaves when in contact
with moist soil develop new plantlets
along the margin.Examples-
The offsprings are genetically identical and therefore
advantageous traits can be preserved.
Only one parent is required which eliminates the need for
special mechanisms such as pollination, etc.
It is faster.
Many plants are able to tide over unfavourable conditions. This is
because of the presence of organs of asexual reproduction like
the tubers, corm, bulbs, etc.
Vegetative propagation is especially beneficial to the
agriculturists and horticulturists. They can raise crops like
bananas, sugarcane, potato, etc that do not produce viable
seeds. The seedless varieties of fruits are also a result of
