Hybrid willows (Salix matsudana Koidz × Salix alba L.), weeping willows (Salix babylonica L.) and hankow willows (Salix matsudana Koidz) were exposed to potassium ferrocyanide to determine the potential of these plants to extract, transport and metabolize this iron cyanide complex. Young rooted cuttings were grown in hydroponic solution at 24.0 ± 0.5°C for 144 h. Ferrocyanide in solution, air, and aerial tissues of plants was analyzed spectrophotometrically. Uptake of ferrocyanide from the aqueous solution by plants was evident for all treat...
