В статье представлены результаты исследований по изучению действия спектрального состава света на морфофизиологические показатели малины (сорт Оранжевое чудо) и ежевики (сорт Black satin) культивируемых в условиях in vitro. / The article presents the results of research on the effects of light spectral composition on the morphophysiological parameters of microclones of raspberries (variety Orange miracle) and blackberries (variety Black satin), cultivated in vitro. The high efficiency of using narrowband and wide-band light-emitting diodes (LEDs) for these purposes is shown. It was found that optical radiation in the studied spectral ranges provided various effects on the growth of plant microshoots, as well as the reproduction coefficient. In a comparative study of the effects of different light sources, the most intense growth of raspberry and blackberry microshoots and an increase in the ultiplication coefficient were observed when using LEDs of the blue spectrum and white LEDs with color temperature 2500 K. Quasimonochromatic green light was favorable for raspberry plants, but not for blackberries. In plant responses to light spectral modes, species and varietal differences appear, which must be taken into account when developing technologies for their light culture in vitro.
