Abstract [eng] We report on the influence of illumination spectrum on grape morphogenesis. The plantlets were cultivated in vitro using an illumination system based on light-emitting diodes (LEDs). Four groups of LEDs emitting in red (at the wavelengths of 660 nm and 640 nm), blue (450 nm), and far-red (735 nm) were exploited and the ratios of the photon flux densities (PFDs) of these spectral components were maintained at selected values. The plantlets were simultaneously cultivated in five growth modules, which were identical except of a preset illumination spectrum. Culture of grape Vitis vinifera L. ‘Gailiūnė’ has been cultivated. Morphological and biometric parameters and concentration of photosynthetic pigments in the plants were measured after 28 or 30 days of the treatment. The total PFD of 40–55 µmol m-2s-1 was found to be optimal for growth of the grape plantlets. Our study was focused on elucidation of the morphogenetic influence of illumination in the blue and far-red regions on the development of grape explants. We demonstrate that spectrally selective solid-state lighting is an effective tool for cultivation of grape culture in vitro and discuss the prospective for using this technique on a commercial scale.
