Feature of formation of photosynthetic apparatus of microcuttings of Populus tremula L. and Betula pendula Roth. at LED-lighting of various spectral composition during ex vitro adaptation

The peculiarities of the influence of LED-lighting of different spectral composition with varying ratios of physiologically significant spectral ranges on biometric parameters and the pigment composition of the leaf plate of microclonally propagated aspen (Populus tremula L.) and birch (Betula pendula Roth.) plants were identified during the adaptation ex vitro, which indicate the species specificity of plants response to the illumination spectrum.
