e0“The resistance of Salix to Cu, Cd, Ni, and Zn was investigated in hydroponic culture, with phytoextraction potential evaluated for Cu. Root elongation (indicative of resistance level) was significantly affected, with considerable variation between and within individual clones.”

Other claims from this paper (13)
- Observation Willow resistance appeared clone or hybrid specific rather than species specific.
- Observation S. caprea clones and hybrids were among the most resistant.
- Observation A second S. caprea clone from another provenance was much less tolerant.
- Observation S. viminalis clones were among the most sensitive.
- Observation S. triandra clones were among the most sensitive.
- Intervention effect Salix had highest resistance to Cd.
- Intervention effect Cu and Ni were extremely toxic to Salix.
- Method / resource The technique identified a resistant S. caprea ecotype from mine spoil.
- Observation Copper concentration reached 2000 μg g-1 (d.wt) in roots after one month of hydroponic culture.
- Observation Copper concentration reached 400 μg g-1 (d.wt) in wood after one month.
- Observation Copper concentration reached 82 μg g-1 (d.wt) in foliage after one month.
- Observation Variation among Salix clones may hinder screening but can supply variation for resistance selection.
- Recommendation Clone selection for metal phytoextraction is feasible, but longer field study is needed.
