In vitro cultivation is a technique that can help solve several environmental problems and preserve biodiversity. It involves cultivating plants in sterile conditions using cuttings from which many new plants can be formed. This allows endangered species to be saved by propagating from a single cutting. In vitro cultivation also produces disease-free plants and can help repopulate areas affected by fires or deforestation. The document outlines the basic materials and conditions needed for in vitro cultivation and provides examples of how it has been used to preserve plant species.

VITRO CULTIVATION

2. The purpose of the in vitro cultivation
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.

3. In vitro cultivation
● But thanks to the in vitro cultivation, all these problems
can be solved by taking an example of any desired plant
specie.

4. What is in vitro cultivation?
● 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
with a reproductive purpose.
Fragments of the stem can be cut,
and introduced into the earth to form roots,
and in this way the plant will grow
and behave in a kind of clone of
the original plant.
Each cutting can be divided
into five other cuttings, minimum,
and so on again and again.

6. MATERIAL
To cultivate in vitro is only necessary a culture chamber,
fluorescent lights or white light led, cylindrical jars, a dark
place and some cuttings.
Also is necessary a type of gel to plant there the cuttings.

7. Must be considered
The light intensity of the camera 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 degrees with
light and 20-22 degrees in the dark.

8. Problems that can be solved by
the in vitro cultivation.
¡¡¡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 in 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 cultivation.
¡¡¡ENDANGERED SPECIES!!!
Endangered species can be saved thanks to the fact
that by in vitro cultivation, conserving only one cutting
can achieve many others saving the species from
extinction.

10. Problems that can be solved by
the in vitro cultivation.
Disease free foods
With in vitro culture, they can be obtained
Disease-free plants as they are isolated from external
factors.

11. ¡¡¡DEFORESTATION!!!
In vitro cultivation helps to be prepared for deforestation,
as there is no need to clear the trees from a plot of land
to grow.
Problems that can be solved by
the in vitro cultivation.

12. So they serve the cuttings?
The cuttings helps us to be able to divide the plant more. In
the circle you can see red of the image, from a cutting can
take five and so on.

13. Putting in practice the in vitro
cultivation
Our school had put in practice
this technique very recently,
following the example of the
university of our city called
``University of Santiago of
Compostela`` (USC). Thanks to
this we are going forward in this
field.

14. Conclusion
We would like to conclude
that in vitro cultivation 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!!!
