Investigated influence Cu(NO3)2 in range of concentration 10-6 - 10-3 mol/l on the Potamogeton perfoliatus L. at adding on water environment for a three day. Is shown, that in the leaves P. perfoliatus, depending on concentration of cupric nitrate in water, the Cu in quantity from 0,08 up to 82,8 mg/g of dry weight is accumulated. The difference in effects of small (10-6. 10-5 mol/l) and increased (10-4. 10-3 mol/l) concentration copper on the biochemical components are detected. Small concentrations copper for the second and third day increase of the contents of common proteins, lipids and pigments. The increased concentrations copper at once within the first day reduce the contents common lipids (at the expense of decrease phospholipids), pigments and citosolic of proteins, increasing the contents of membrane proteins. Is assumed, that in the leaves P. perfoliatus at excess copper the multilevel protection against metal and it detoxication, connected with modification membrane lipids and additional synthesis of proteins implements.
