Effect of temperature on the uptake and metabolism of cyanide by weeping willows.

Plants' uptake and metabolism of cyanide in response to changes in temperature was investigated. Pre-rooted weeping willows (Salix babylonica L.) were exposed to hydroponic solution spiked with potassium cyanide for 2-3 d.

The potential for phytoremediation of iron cyanide complex by willows.

Hybrid willows (Salix matsudana Koidz x 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.
