Abstract:
The following Master Thesis focused light emitting diodes (LED) and their effects on growth rate, nitrate content, relative photosynthesis rate and carbon content of selected plants, grown on hydroculture. Different experimental conditions (e.g. light intensities, light spectra and plant species) allow comparisons and are the basis of this work. The nitrate content in vegetables, which were grown on hydroculture under light emitting diodes, did not exceed the limit of the EU-regulation 1258/2011. A proportion of green light may cause a decrease in the nitrate content. Furthermore, it was demonstrated, that long lasting and high light intensities cause stress reactions in the plants, which is detectable by the C13 value. Finally, the suitability of the use of light emitting diodes (LED) in plant tissue culture was tested. The results show that LED’s are a power saving alternative compared to fluorescent tubes, with equal results on all tested species. These results should show the development and potential of crop production with artificial light in the urban space.
