Cultivo in vitro #scichallenge2017

  1. 1. BENEFITS THAT CAN SOLVE THE IN VITRO CULTIVATION By: Carlos García Andrés Pensado David Bueno
  2. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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!!!
  15. 15. THE END
