Chlorophyll a fluorescence parameters: (A) ratio of variable (Fv) to maximum (Fm) fluorescence and (B) efficiency of quantum yield of electron flow throughout Photosystem II (PSII) measured on leaves of wooly digitalis cultivated with wastewater (filled circles) and nutrient solution (open circles) and foxglove cultivated with wastewater (filled triangles) and nutrient solution (open triangles). Values are means ± standard deviations; n = 20.

Concentrations of (A) suspended solids (SS), (B) biochemical oxygen demand (BOD5), and (C) chemical oxygen demand (COD) in the wastewater during 72 h of treatment in the planted channel with wooly digitalis (filled circles) and foxglove (open circles) and in the unplanted channel (filled triangles) in July 2000. The dashed line indicates the legal discharge level. Values are means ± standard deviations; n = 5.

Concentration of (A) suspended solids (SS), (B) biochemical oxygen demand (BOD5), (C) chemical oxygen demand (COD), (D) total P, and (E) total nitrogen in the wastewater before the treatment and after 48 h of treatment in the planted channel with wooly digitalis and foxglove and in the unplanted channel (June–December 2000). The dashed lines indicate the legal discharge level and the dotted lines indicate the legal discharge level in eutrophically sensitive areas. Arrows represent wooly digitalis death. Values are means ± standard deviations; n = 5.
