  1. The effects of phosphorus level (P), submerged macrophyte species assemblage (S), and their interaction (P*S) on the Potamogeton maackianus biomass per plant (PM), Hydrilla verticillata biomass per plant (HV), chlorophyll a level (Chl a), and inhibition ratio of phytoplankton (IRP) at each day of measurement. Significant effects (p < 0.05) are indicated in bold text.
