Phosphate uptake kinetics for four species of submerged freshwater macrophytes measured by a 33P phosphate radioisotope technique

The results indicate that at low lake water Pi concentrations L. uniflora is able to survive on the Pi pools in the sediment porewater. M. alterniflorum showed high affinity for Pi at both low and high Pi concentrations by both roots and shoots, and suggests that M. alterniflorum is a strong competitor at both low and high Pi concentrations.
