“…While this response likely resulted from differences in treatments and reductions of growth from higher contaminant levels, some of the clones appeared to perform better than others at specific sites. This is similar to results shown by Baldantoni et al () in the laboratory who tested poplar heavy metal phytoextraction and by Zalesny and Bauer () in the field who tested poplar petroleum phytoremediation, and suggests that phyto‐recurrent selection of clones at field sites is advisable when carbon sequestration is a consideration of phytoremediation systems.…”

“…The effectiveness of phytoextraction and phytostabilization has been shown to be highly clone‐specific. For example, Baldantoni, Cicatelli, Bellino, and Castiglione () showed a nearly 10‐fold increase in cadmium phytoextraction for clone ‘N12’ ( P. nigra ) relative to ‘AL22’ ( P. alba ), while the latter was superior for phytostabilization of copper. Likewise, genotypes of P. euphratica and P .…”

Short rotation woody crops (SRWCs) including Populus species and their hybrids (i.e., poplars) are ideal for incorporating biomass production with phytotechnologies such as phytoremediation. To integrate these applications, 15 poplar plantings from nine long-term phytoremediation installations were sampled from 2012 to 2013 in the Midwest (Illinois, Iowa, Wisconsin) and Southeast (Alabama, Florida, North Carolina) United States. In this review, we report summary results of this sampling and how performance at each site compared with comparable phytoremediation systems in the literature. We review significant genotypic differences from each planting within the context of provisioning (i.e., biomass production) and regulating (i.e., carbon sequestration) ecosystem services and how they relate to the need for a cleaner environment during times of accelerated ecological degradation. Overall, the contaminated poplar sites provided these ecosystem services comparable to noncontaminated poplar sites used for bioenergy and biofuels feedstock production. For example, phytoremediation trees at the Midwestern sites had biomass values ranging from 4.4 to 15.5 Mg ha −1 y −1 , which was~20% less relative to bioenergy trees (p = .0938). Results were similar for diameter and carbon, with some genotype × environment interactions resulting in phytoremediation trees exhibiting substantially greater growth and productivity (i.e., +131% at one site). As illustrated in the current review, phytoremediation success can be increased with the identification and deployment of genotypes tailored to grow well and tolerate a broad diversity of contaminants (generalists) (i.e., 'DN34', 'NM6', '7300501') versus those that significantly outperform their counterparts under unique site conditions (specialists) (i.e., '220-5', '51-5', 'S13C20').

“…Anyway, Cd has generally a high soil bioavailability (Baldantoni et al, 2010) and has higher mobility in plants compared to other heavy metals (Greger, 2004;Akoumianakis et al, 2008;Zhang et al, 2013), being easily transported by roots to shoots (Baldantoni et al, 2014).…”

“…As a general rule, metal concentrations are normally higher in roots than in shoots (Garate et al, 1993;Kabata-Pendias, 2011). However, in several plants (Baldantoni et al, 2014), and also in leafy vegetables grown on unpolluted soils (Kabata-Pendias, 2011), Cd is primarily allocated in leaves. Since leafy vegetables, such as lettuces, endives and similar horticultural crops have a relatively high potential for Cd uptake and translocation (Peijnenburg et al, 2000), they are considered Cd accumulators (FAO, 1983).…”

“…Therefore, selection and/or breeding of suitable plant genotypes based on biomass production, accumulation potential, root traits, growth rate, environmental suitability and metal resilience are required for their use in the remediation of heavy metal contamination (Wang et al 2014). In the last ten years, research was focused on highly productive crop plants, such as crops, maize, sunflower, rice (Komarek et al 2007, Murakami & Ae 2009), as well as on short rotation forest trees, i.e., willow and poplar (Fernàndez-Martínez et al 2014, Baldantoni et al 2014. Phytoextraction carried out with the use of other woody plants can be extremely interesting for the restoration of contaminated sites, where environmental conditions are unsuitable for growing energy plants, as well as for their longer reproductive cycles (Paoletti & Günthardt-Goerg 2006, Cocozza et al 2012.…”

The relevance of the environmental pollution by heavy metals warrants the necessity to develop and assess more efficient plant-based technologies. This study was conducted to evaluate a quick screening approach in order to investigate the cadmium (Cd) and copper (Cu) phytoextraction potential of Quercus pubescens in a micro-propagation system. Increasing concentrations of Cd (0, 5, 50, and 250 µM) and Cu (0, 5, 50, 250 and 500 µM) were separately applied to evaluate the effect of metals on their absorption and accumulation in downy oak plants. At high concentrations, Cd and Cu significantly reduced the dry biomass of shoots and roots and the plant tolerance index. Cd was toxic at increasing concentrations, inducing higher reduction of shoot dry mass than roots, whereas Cu increased dry mass at 5 µM. This study represents the first attempt to assess Cd and Cu uptake in Q. pubescens under in vitro conditions. The in vitro screening potential is meanly related to the following purposes: (i) proper selection of plant materials resilient to excess metals in the growth substrate; (ii) efficient removal of metals by the selected tree species; (iii) minor interference with the growth of plants accumulating metals in their tissues; (iv) rapid provision of plant materials for tree breeding programs.
