Aim. Modern light-emitting diodes cover all of the visible range of the optical spectrum and with the right LEDs color groups combination any spectral composition can be achieved. Also, the use of different wavelength combinations can influence plants grows and development. The aim of the present work was to study the monochrome blue LED lighting effect on the morphologic characteristics of some medical plants during in vitro cultivation. Methods. Digitalis pur-purea L., Aerva lanata L. Juss. ex Schult. and Cathranthus roseus G. Don in vitro cultivated plants were used for monochrome blue LED lighting effect estimation. Spectrometric methods of photosynthetic pigments and flavonoid content estimation were used. Results. In vitro plants grows with 440–460 nm LED lighting causes adaptive morpho-physiological changes with pigments and flavonoids content decrease. An increase in shoots formation, plant grows deceleration and interstices shortening were also found. Conclusions. Obtained results suggest insufficiency of mono-chrome LED lighting and the need of optimal spectral composition determination for successful plants cultivation. Keywords: LED lighting, Digitalis purpurea L., Aerva lanata L. Juss. ex Schult., Cathranthus roseus G. Don, morpho-physiological changes.
