The comparisons showed that the intensity of water ‘bloom’ caused by blue-green algae (cyanoprokaryotes) was evidently higher, and this process was prolonged, in the years of lower solar activity. The ‘bloom’ intensity decreases in years of high solar activity (11-year cycle). Such effect is connected with the peculiarities in the structure and photochemical activity of pigment phothosystems in different taxonomic groups of algae. %8 2004-03-10
