其他摘要：A semiconductor light-emitting diode based lamp with variable spectrum for investigation and control of photophysiologicprocesses in plants under artificial-climate conditions is described. High-power emitters with the peak wavelengths of the spectral powerdistribution functions at 453 nm (the flux density from 0 to 9 μmol/m2s), 640 nm (0 to 150 μmol/m2s), 660 nm (0 to 10 μmol/m2s) and731 nm (0 to 3 μmol/m2s) were used for the spectral ranges, which are responsible for control of the photosynthetic andphotomorphogenetic processes in plants.Results on the influence of variable-spectrum illumination of vegetables (lettuce Grand Rapids, radish Saxa) are presented. Analysisof photosynthetic and photomorphogenetic processes shows that these processes can be controlled by selection of a particular spectralcomposition of the incident light and circadian regime of illumination.
