Advances in the use of Halimione portulacoides stem cuttings for phytoremediation of Zn-polluted soils

The salt-marsh shrub Halimione portulacoides can grow in soils containing extremely high concentrations of Zn and stem cuttings have recently been shown to aid the recovery of polluted soils although further work on this methodology have is required. A greenhouse experiment was carried out to analyz...

A greenhouse experiment was carried out to analyze the effects of a range of Zn concentrations (0–130 mmol l−1) on the establishment, growth and photosynthetic performance of stem cuttings of different sizes of Halimione portulacoides, with the aim of determine the phytotoxicity thresholds and the optimal initial size of the cuttings to be used in phytoremediation strategies.
