Other claims from this paper (13)
- Intervention effect Root elongation of Salix was significantly affected by metals and varied between and within clones.
- 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.
