Artificial Vegetative Propagation: Cutting - Reproduction in Plants, Science, Class 7 Video Lecture

hello friends this video under
production in plants part 8 is brought
to you by exam for your calm no more
fear from exam so these were all the
methods of RT natural vegetative
propagation maybe we saw the leaves
roots and stems they exist that is how
they exist in nature we do not do any
modification whether you talk about the
potato or the onion or the prime phylum
we are not making any changes to it so
whatever it is that is present in them
by itself and they give rise to new
plants with similar characteristics as
their parents so we really do not have
any control on which type of plants will
get produced but when we talk about
artificial vegetative propagation here
we have certain methods like cutting
layering grafting and with these methods
we have our own control so if we hold on
certain characteristics in a new plant
so we can do that so let's say if I want
a plant and I'm just giving you a rough
example let's say that you want a plant
a rose plant where the roses should be
half yellow and partially red in color
so if that's what you want
so by natural vegetative propagation
that is not possible because this is
something which you wish but natural
vegetative propagation happens by itself
so it is not under your control but with
artificial vegetative propagation you
can actually needles you can actually
take some part of a red rose plant and
some part of a yellow rose plant and
then you can mix and match them to form
a new plant which will give rise to rose
roses which are partially yellow and
partially red in color so that is
artificial vegetative propagation that
is it is completely under our control
and we can get desired characteristics
of the new plant so now we will spend
some time understanding each of the
methods and their artificial vegetative
propagation in that these days this
process of artificial vegetative
propagation is utilized to a very large
extent in fact it is to some extent
exploited by farmers and gardeners for
commercial property
of plants that is the wanton produce
more red roses plants because maybe red
roses it is more beneficial or they earn
more profit by selling red roses so what
they do they use this method of
artificial vegetative propagation to
increase the production of red roses so
to some extent it helps them and to some
extent they sometimes exploited its
plight this entire process so let us
look at the first artificial negative
propagation process that is cutting so
what can we do with cutting so here it a
plant part is cut from the pattern and
put into the soil which later give rise
to a new plant so have you ever seen
that in if you have a small garden in
your house you would have seen that you
and your neighbors if you like a plant
which is there in your neighbor's house
what do you do sometimes you just take a
stem of that turn stem with a branch
something and then you come back to your
home and you put it into the soil and
then over a period of time it gives rise
to a new plant so basically what did you
do you just took one part of that plant
from your neighbor's garden and then you
have put it in your house and you got a
new plan so basically you have you help
the plant to reproduce a new plant was
born with the help of one plan apart
from the parent so this is called
cutting so because you are actually
cutting one part and that part is
capable of giving rise to new plan so
let us look at examples the most common
example of stem cutting happens in rows
so if you want to have a new roast and
all you need is a stem stem with some
leaves and then you put it into the soil
and over a period of time you get a new
plant the similar thing is true for
sugar cane as well so there are certain
lunch when root cutting helps now not
the stems of all plants are not capable
of giving rise to a new plant so in some
plants that capability is with the roots
for example that here in case of Daniel
kind of flower it is it's a quite big
inside everything
roughly this is how it looks it is also
available in many different colors so in
these of these plants if you take if you
cut a stem of this plant and and then
put it in your house I think I don't
think you'd get a new plant because the
stems of these plants are not capable of
giving a hints to entire plant but the
roots are so in case of gallium you have
these kinds of roots we have spoken
about the roots net these roots are also
modified roots and they help in food
storage you remember why we were talking
about natural vegetative propagation we
said that that can happen with the help
of roots so Dahlia was one such example
of natural vegetative propagation by
roots so these roots such rooms are
swollen
thick fleshy and have been food storage
and they are capable of bearing birds so
they can give rise to new branch in this
case we have to cut the root of the
plant and then put it into the soil over
a period of time the birds will develop
and birch will give rise to new plants
