Effect of different LEDs light spectrum on potato (Solanum tuberosum L.) in vitro (review)

Potato (Solanum tuberosum L.) is a significant and valuable crop for the economy of many countries. It provides people nutrition and national food security. To obtain healthy potato planting material, propagation in vitro culture is carried out. The problem of increasing the propagation efficiency at this stage is very relevant and can be solved by optimizing the lighting parameters, including the spectral composition of the emitter. The review of published works mainly over the last 20 years concerning the study of the effect of LED lighting of different spectral composition and power on regenerated potato plants, grown in vitro, is given in this paper. Morphometric and physiological parameters of potato plants are given, which can be influenced by changing the spectral composition of illumination. Data on lighting recommendations for different varieties of potato are given. This review may be useful for organizations involved in potato micropropagation, as well as for research teams developing technologies for optimal potato cultivation.
