TY - JOUR N2 - The role of two submerged macrophyte species (Ceratophyllum demersum and Potamogeton pectinatus) as biological factor affecting concentrations of P and chlorophyll a concentrations was tested under laboratory conditions. In general, after four weeks exposition, the significant reduction of TP, P-PO4 and chlorophyll a was observed in all experimental variants (aquaria with P. pectinatus, C. demersum and P. pecinatus + C. demersum), but the highest decrease of phosphorous compounds (TP, P-PO4) was noted in aquarium with C. demersum, whereas the highest decline of chlorophyll a concentration (biomass of phytoplankton) was observed in aquarium with C. demersum + P. pectinatus. Together with the reduction of chemical parameters the biomass of macrophytes as well mean length of plant shoots significantly increases. The highest growth of shoots and biomass showed C. demersum.
