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.}, type={Artykuły / Articles}, title={Effects of submerged macrophytes on the concentrations of phosphorous and chlorophyll a under experimental conditions}, URL={http://ochroma.man.poznan.pl/Content/107219/PDF-MASTER/15%20Tarkowska-Kukuryk.pdf}, keywords={macrophytes, shallow lakes, trophic conditions, eutrophication}, }
