Ways of Reproduction
Stem
cutting
• Some plants do not produce flowers or seeds.
• Plants such as ferns and mosses are called nonflowering plants and produce spores instead of seeds.
• Spores are microscopic specks of living material.
• Ferns produce their spores on the undersides of the
leaves called fronds.
• The fronds form brown spots on the undersides of the
leaves.
• If you use a microscope to look at the spores, you can
see that the spores are in a variety of shapes and are
unique to each kind of fern.
WE DID NOT ADD IN MUSHROOM AS IT IS A FUNGI.
Shoots & suckers of plants
 In Botany, a 'sucker' is a plant growing not from
a seed but developed of a meristem from the
root at the base or at a certain distance of a tree
or shrub.
 This is a phenomenon of natural asexual spread,
also known in plants as vegetative.
 It is a plant propagation strategy and the
complex of individuals formed by a mother plant
and all its clones produced form a single genetic
individual, a genet.
 The plant suckers are clones from the mother
plant. The plant will be a genome identical to
that which it arose.
 Many species form new plants from basal shoot
as Canada thistle, cherry, Apple, Ligustrum,
Hazel, Tree of Heaven and guava.
Shoots & suckers of plants
• A shoot or cane grows from a bud at the base of
a tree or shrub or from its roots.
• A plant that produces suckers is referred to as
surculose.
• Root suckers may emerge some distance from the
originating plant. Suckers also may arise from the
stumps of trees that have been cut down.

• The process of removing a plant part then having that part
grow into a genetically exact replica of the original plant is
called cutting propagation.
• It is a plant cloning technique.
• Plants can be propagated from root, leaf or stem cuttings.
When propagating plants by cuttings, it is important to
remember that the cutting is a living plant part that has
been separated from its life support system.
• Cutting propagation is often the preferred method for plant
propagation because it is the easiest and most cost
effective way to produce a clone of a particular parent
plant.
• Other methods that are more difficult or more expensive
may exist but are often not chosen.

How To Grow A Plant By Stem Cutting?
• Step 1 : Get a stem from a
healthy plant which has just
bloomed. It should be the
size of a pencil, or slightly
longer.
Step 2 : Fill a pot with
soil. Water it thoroughly
and allow water to drain.
Use a pencil to make a
hole in the soil for your
cuttings.
Step 3 : Cut your stem
into 6 to 10 inches pieces
and cut away 1 inch of
the outside of the stem
which will leave an
opening for the roots.
Step 4: Dip the bottom
of stem into water, tap
off any excess water and
dip into rooting
hormone as it helps
speed up the process of
growing roots.
Step 5 : Lightly press the
stem into the hole in the
soil. there must be no air
pockets.
Step 7 : They don’t have
roots yet , so they take in
moisture through the
stem. Use a moisture
barrier, place them in
it(creating a greenhouse
effect). Water the plants 2
to 3 times a day with a
spray bottle. Make sure
that the soil remains
moist at all times but not
too wet!
