[Effect of light of different spectral composition on pigment accumulation, productivity and effectiveness of use of absorbed energy in photosynthesis during the developmental cycle of Chlorella].

The paper deals with the effect of light of different spectral composition on the duration of developmental cycle, pigment accumulation, productivity and efficiency of the use of absorbed energy in photosynthesis during the developmental cycle of Chlorella. An extremely high efficiency of using the green spectrum region in photosynthesis (21,0%) was observed. The efficiency of using absorbed radiation of the red (12%) and blue (6%) spectrum regions is also very high, but significantly lower than that of the green one. The activity of metabolic processes in Chlorella cells differs in various spectrum regions during different developmental cycles and is determined by the acting spectrum.
