SINOPSIS

Dynamics of chlorophylls content in the submerged macrophytes Najas guadalupensis, Ceratophyllum demersum and Myriophyllum spicatum under elevated concentration of phosphorus in the model aquatic medium was studied. It has been found that in chronic experiments (14 days) content of chlorophylls in N. guadalupensis decreased under lesser concentration of phosphorus (starting from 1 mg P/dm³) as compared with C. demersum (starting from 5 mg P/dm³) and M. spicatum (10 mg P/dm³). Species specificity of phosphorus absorption by the plants depending on its concentration in water has been revealed.
