“…The large biomass yield can be used for economic opportunities, such as bioenergy, solid wood production and reconstituted products (Rockwood et al 2004). The extended and deep root apparatus can explore a large volume of soil; the impact on trophic chains is low, and the adaptability of some tree species to grow in marginal soils is well-established.…”

Purpose This work was planned for providing a useful screening tool for the selection of Populus alba clones suitable for phytoremediation techniques. To this aim, we investigated variation in arsenic, cadmium, copper, and zinc tolerance, accumulation and translocation in three poplar clones through an in vitro screening. Poplars have been widely proposed for phytoremediation, as they are adaptable to grow on contaminated areas and able to accumulate metals. The investigation of possible differences among poplar clones in metal tolerance and accumulation deserves to be deeply studied and exploited for the selection of the more suitable tool for phytoremediation purposes. Methods In vitro multiplied microshoots of a commercial and two autochthonous P. alba clones were subcultured on hormone-free WPM medium for 1 month and then transferred for 2 weeks onto media containing different concentrations of the metals investigated. At the end of the treatments, plantlets were sampled, weighed, and mineralised by wet ashing. Metal concentrations were determined by ICP-OES. Results For the metal concentration used in the experiments, our clones of P. alba showed variation in metal tolerance, metal accumulation and content. The fast-growing commercial clone, even if rarely showing the highest plant metal concentration, displayed the highest metal content, suggesting biomass production as the key factor in evaluating the phytoextraction capacity of P. alba clones for the metals studied. Conclusions Data demonstrated that in vitro screening of cuttings represents a valuable way of assessing the ability of different poplar clones to take up, tolerate and survive metal stress.

“…In fact, these Salicaceae are known not only to be adaptable to grow on contaminated areas, but also to be capable of accumulating heavy metals . Moreover, poplar cultural management by means of short rotation coppice cultures is another advantageous feature to be considered in phytoremediation strategies (Rockwood et al 2004).…”

“…Currently there are a number of reports available on metal accumulating plants that are used in removing toxic metals from the soil (Delorme et al, 2001;Whiting et al, 2001;Glick, 2003;Sheng and Xia, 2006). Ricinus communis (castor bean) is one of such plant species, which has attracted considerable attention because of its ability to grow in heavily polluted soil together with its capacity for metal ion accumulation (Prasad and Freitas, 2003;Rockwood et al, 2004;Cecchi and Zanchi, 2005). In addition, R. communis is an industrial crop with multiple non-food uses and is an excellent rotation and companion crop.…”

The metal resistant-plant growth-promoting bacterial (PGPB) strains PsM6 and PjM15 isolated from a serpentine soil were characterized as Pseudomonas sp. and Pseudomonas jessenii, respectively, on the basis of their morphological, physiological, biochemical characteristics and 16S rDNA sequences. Assessment of plant growth-promoting parameters revealed the intrinsic ability of the strains for the utilization of 1-aminocyclopropane-1-carboxylic acid as the sole N source, solubilization of insoluble phosphate and production of indole-3-acetic acid (IAA). Further, a pot experiment was conducted to elucidate the effects of inoculating metal resistant PGPB on the plant growth and the uptake of Ni, Cu and Zn by Ricinus communis. Inoculation of Pseudomonas sp. PsM6 or P. jessenii PjM15 increased the shoot and root biomass of R. communis grown in non-contaminated and contaminated soil. However, the maximum biomass was observed in the plants inoculated with strain PjM15. This effect can be attributed to the solubilization of phosphate and production of IAA. Inoculation of Pseudomonas sp. PsM6 and PjM15 did not greatly alter the organ metal concentrations except Zn which concentration was higher in root, stem and leaf of inoculated plants. The results of metal extraction with PGPB strains showed that PsM6 was more efficient at solubilizing Zn than PjM15, and that PjM15 was better at solubilising Ni and Cu than PsM6. Owing to its wide action spectrum, the metal resistant PGPB could serve as an effective metal sequestering and growth-promoting bioinoculant for plants in metal-stressed soil. The present study has provided a new insight into the phytoremediation of metal-contaminated soil.

A partire dall'inizio di questo secolo la politica energetica nazionale, per ridurre le emissioni di CO 2 , ha favorito l'impiego delle biomasse legnose per la produzione di energia calorifica e/o elettrica in sostituzione dei combustibili fossili (carbone, petrolio, gas). Questo fatto ha comportato un progressivo aumento delle importazioni di biomassa legnosa: nel 2013 l'Italia, infatti, ha importato una quantità di assortimenti potenzialmente destinabili a fini energetici prossima a 3.8 milioni di tonnellate, diventando il primo importatore mondiale di legna da ardere, il terzo di pellet a uso civile e di residui e scarti legnosi (Favero & Pettenella 2014, Andrighetto et al. 2015. Si tratta di una tendenza ormai consolidata da almeno un decennio (Favero & Pettenella 2014).È concreto il rischio che l'Italia, nel medio e lungo termine, non possa continuare ad approvvigionarsi di biomassa legnosa sul mercato internazionale, almeno nelle quantità attuali. Si prevede infatti che dal 2025 si avrà a livello mondiale una contrazione dell'offerta di biomassa legnosa, che determinerà problemi di approvvigionamento e forte competizione tra i Paesi interessati a questo tipo di assortimento legnoso (Favero & Pettenella 2014).In un tale contesto la coltivazione di cloni di eucalitto nelle zone a clima mediterraneo dell'Italia centro-meridionale, più che una opportunità, si configura come una esigenza ineludibile per soddisfare, almeno in parte, la forte richiesta interna di biomassa legnosa per uso energetico (cippato, legna da ardere, carbone vegetale, pellet).L'eucalitto, pianta di origine australiana, fa parte della nostra flora da più di due secoli. La prima testimonianza scritta infatti risale al 1803 ad opera del Graefer che descrisse alcuni eucalitti presenti nei giardini della Reggia di Caserta. Le piante avevano già qualche anno per cui presumibilmente erano sta- The cultivation of eucalyptus clones in areas of central-southern Italy with a Mediterranean climate has become necessary in order to meet, albeit in part, the strong domestic demand of woody biomass for energy use (wood chips, firewood, charcoal, pellets). In the last ten years, in fact, Italy has become one of the world's largest importers of woody biomass for energy use. In our country the eucalyptus can be grown following the principles and methods of planted forest systems. The aim of the present paper is to point out the main problems that this culture can face in the national pedoclimatic context, together with their possible solution. Among the possible solutions, the most sustainable are suggested, which may contribute to both economic and energy savings for the culture and for other human activities. These solutions, widely used in various contexts, are briefly described, and references to the literature of the sector are provided for a deeper insight.
