Аннотация
It was found that the additional lighting affects habіtus of in vitro plants: red light correction increases the growth of potato cultivars such as Shchedrik, Tyras and Suvenir Chernihivskyi, and blue light correction leads to a significant reduction in height of Suvenir Chernihivskyi potato cultivar and to the accelerated formation of stolons in all tested varieties. The chlorophyll content in the leaves of potato plants was increased with additional lighting. It depended both on the light spectra and the reaction of varieties to lighting.
