“…Considering the BCF for these elements (Table 2), these poplar hybrids can be considered as Cd and Zn accumulators. These data are in agreement with previous studies where the largest Cd concentrations in aboveground tissues were measured in leaves of P. trichocarpa × P. deltoides (209 mg kg −1 DW) growing on a polluted site containing up to 300 mg Cd kg −1 DW (Robinson et al 2000). Willow is also an accumulator of Cd and Zn but to a lower extent.…”

“…Salix might be sufficiently tolerant to decrease the plant-available heavy metal load in contaminated soils, whilst still maintaining high yields in a phytoremediation system (Punshon et al 1995;Punshon and Dickinson 1997). Poplar was also found to be a Cd accumulator: leaf Cd concentrations of Populus trichocarpa × Populus deltoides reached 209 mg kg −1 dry weight (DW) when grown on a polluted site containing up to 300 mg Cd kg −1 DW (Robinson et al 2000). However, most of the previous studies on this topic compared either a rather limited number (<6) of species (Robinson et al 2000;Rosselli et al 2003;Mertens et al 2004;Sebastiani et al 2004;Wieshammer et al 2007) or a high number of clones of a single species (Pulford et al 2002;Laureysens et al 2004;Dos Santos Utmazian and Wenzel 2007).…”

Metal accumulation was investigated in a range of woody species that were planted on Cd-, Znand Pb-polluted sites in North of France. The study is unique in that we directly compare a large number of woody species (25). The highest accumulation of Zn and Cd was found in the Salicaceae family members with up to 950 mg Zn kg −1 dry weight (DW) and 44 mg Cd kg −1 DW in leaves of Populus tremula × Populus tremuloides. Zn content was positively correlated with Cd content, both in leaves and stems. Pb concentration was generally low and was speciesindependent. Oak and birch species accumulated more Mn as compared to other woody species. A seasonal variation in metal accumulation could be found. Although soil compositions and metal bioavailabilities differed amongst the experimental sites chosen in this study, variation of metal concentrations within a given species was small. High bioconcentration factors for poplar and willow suggested the high potential of these species over other woody species for metal accumulation. Taken together, these data suggest that poplar and willow species are good candidates for phytoremediation programmes.

“…Salicaceae are also reported to grow even in severe soil conditions and to accumulate heavy metals , Berndes et al 2004). Many studies have thus been focused on the use of willows and pop lars in phytoextraction (Riddell-Black 1994, Labreque et al 1995, Bañuelos et al 1999, Robinson et al 2000, Aronsson & Perttu 2001, Granel et al 2002, Klang-Westin & Perrtu 2002, Hammer et al 2003, Vyslouz ilová et al 2003, Vervaeke et al 2003, Madejou et al 2004, Sebastiani et al 2004, Kuzovkina et al 2004, Robinson et al 2005, Giachetti & Sebastiani 2006, Dos Santos Ut mazian et al 2007, Jensen et al 2009). These species can be ad vantageously exploited in short rotation cop pice cultures (SRC), a strategy whose appli cation in phytoremediation presents intere sting and economically promising perspe ctives (Scarascia-Mugnozza et al 1997, Paulson et al 2003, Laureysens et al 2004a, Laureysens et al 2004b, Rockwood et al 2004, Dickinson & Pulford 2005, Witters et al 2009).…”

Soil contamination by heavy metals is among the most serious danger for the environment, and new methods for its containment and removal are claimed, in particular for agricultural soils. Phytoremediation is an emerging, potentially effective technology applicable to restoration of contaminated soils and waters. Besides hyperaccumulator herbaceous plants, several woody species are now considered of interest to this aim. Many woody plants are fast growing, have deep roots, produce abundant biomass, are easy to harvest, and several species revealed some capacity to tolerate and accumulate heavy metals. Biotechnologies are now available for investigating this potential and enlarge the possibilities of exploitation of trees for remediation. The use of in vitro cultures, the role of bacteria and mychorrhizas, the powerful tool of genetic engineering, are some of the aspects focused in this paper that open prospects of global relevance for a better understanding of the processes related to the uptake of heavy metals by woody plants. In recent years significant progress has been made in identifying native plants and developing genetically modified tree plants for the remediation of heavy-metal polluted environment. Despite the intensive research developed in the last years, few field trials demonstrated the feasibility of the approach described, therefore much efforts should be addressed to this goal

“…Poplars and willows have the potential to provide a cheap method of cleaning up Cdcontaminated soils because of their high bio mass production and high Cd bioaccumula tion coefficient (e.g., Dickinson 2000, Robinson et al 2000. Plant biomass, metal tolerance, and metal accumulation in roots and leaves vary greatly between clones (Dos Santos Utmazian et al 2007).…”

A screening in hydroponics was carried out to assess the potential of Cd uptake and metal accumulation in roots of 4 poplar and 2 willow clones. Rooted cuttings were exposed for 3 weeks to 50 μM Cd sulphate in a growth chamber. Salicaceae clones were discriminated in their potential to absorb and distribute Cd in root tissues considering the interaction between metal and macronutrients. SEM-EDXMA was useful to investigate structural modifications and to identify in situ concentration and distribution of elements in roots, establishing indirect correlations between accumulation and localization of the metal. Overall, observations suggested differential patterns between species and clones in accumulating Cd within the root profile. In conclusion, Cd accumulation in root levels would hardly be a useful indicator of the ability of plants to translocate metal, independently from other parameters, while Cd location in the root cross-section levels could suggest clone-specific control mechanism to mineral uptake
