ResumoThe influence of water level variation (flood pulse) on the biomass and chemical composition of the aquatic macrophyte Eichhornia azurea, was investigated in a tropical oxbow lake of the Rio Mogi-Guacu, State of Sao Paulo, Brazil. The flood pulse causes an increase in total nitrogen content from 0.67 to 1.35 mg/L and total phosphorus content from 10.5 to 101.0 μg/L of the water. This fertilization, associated with other factors, determines a typical seasonal variation in the biomass and chemical composition of the macrophyte.
