The innovative LED light source (Sun Box) with spectrum in the wavelength range 440-660 nm was used in experiment for study the influence of light intensity on the growth and development of plants. The illumination intensity of 75 and 230 μmol/s*m2 promoted development of Stevia rebaudiana plantlets with optimal values of morphometric parameters and well developed roots, which is important for plantlet adaptation to soil conditions. For Solanum tuberosum plantlets (Snegir and Rozhdestvenskiy cultivars), radiation intensity of 135 μmol/s*m2 was optimal for micropropagation. The illumination intensity of 230 μmol/s*m2 led to a formation of plantlets with the largest total fresh mass among experimental groups. Sun Box light with intensity of 75 μmol/s*m2 could be applicated for micropropagation of these cultivars: plantlets were the highest with the largest internodes number. Thus, the plant response to different light intensity was species-spesific, and – in case of potato plantlets – cultivar-spesific.
