2. The purpose of the in vitro micropropagation
Some places of important biodiversity
have been destroyed by people actions
(deforestation, desertification, or other
enviromental problems).
Two examples could be the fire in
Madeira´s island or the fire of ``Fragas
do Eume`` in Galicia, Spain.
3. In vitro micropropagation
● But thanks to the in vitro micropropagation, all
these problems can be solved by taking
samples of any desired plant specie.
4. What is in vitro micropropagation?
● It´s a technique of plant reproduction in totally
aseptic conditions in which from a cutting,
more plants can be formed.
5. What is a cutting?
Cuttings are fragments of separate plants with a
reproductive purpose. Fragments of the stem can
be cut, and introduced into the soil to form roots.
In this way the plant will grow and behave as a
clone of the original plant.
Each cutting can be divided into five other
cuttings, minimum, and so on again and again.
6. MATERIAL
To grow in vitro plants you will need a culture
chamber, fluorescent lights or white light leds,
cylindrical jars, a dark place and some cuttings.
You also need a type of gel to plant there the
cuttings.
7. Must be considered
The light intensity of the chamber must be taken
into account (between 1500 lux and 2000 lux).
The light must be white, and it must be cold.
Sunlight should not exceed 15000 lux.
It has to be 18 hours with light and 8 hours in the
dark, 24-26 °C with light and 20-22 °C in the dark.
8. Problems that can be solved by the
in vitro micropropagation.
FIRES
In case of a fire, the plants that were in vitro
culture, can be planted in the affected area,
recovering its biodiversity. If this technique had
been used, many important species could have
been saved after fires, such as the fire at Fraga
do Eume, which affected a considerable group
of important plant species.
9. Problems that can be solved by the in
vitro micropropagation.
ENDANGERED SPECIES
Endangered species can be saved thanks
to the fact that with in vitro micropropagation,
conserving only one cutting can achieve
many others saving the species from
extinction.
10. Problems that can be solved by
the in vitro micropropagation.
Disease free foods
With in vitro culture, disease-free plants
can be obtained,
as they are isolated from external factors.
11. DEFORESTATION
●
● In vitro cultivation helps to be prepared for
deforestation, as the new plants can be used
to reforest the land.
Problems that can be solved by
in vitro micropropagation.
12. Applying the in vitro
micropropagation
Our school had put in practice this
technique very recently, following the
example of the university of our city
called ``University of Santiago de
Compostela`` (USC). Thanks to this we
are going forward in this field.
13. Conclusion
We would like to conclude that in vitro
micropropagation is a technique that can save
many forests from desertification or other
problems, improve food quality and save many
plant species for a very low price which is what
the material costs.
It is a way of learning, a way to save our forests
and ourselves.
