“…PC-metal complex was also reported in other plants such as tobacco (Vogeli-Lange and Wagner, 1990) and wheat (Stolt et al, 2003). These results suggest accumulation of Cd and Zn, and Pb exclusion as tolerance strategies of V. faba L. Similar data have been reported by Vogel-Mikuš et al (2005) in Thlaspi praecox Wulf.…”

a b s t r a c tVicia faba L. seeds were grown in a pot experiment on soil, mine tailings, and a mixture of both to mimic field situations in cultivated contaminated areas near mining sites. Metals in the substrates and their translocation in root, stem and leaf tissues were investigated, including morphological responses of plants growing on mine tailings. Metal concentration -and generally bioaccumulation -was in the order: roots > leaves > stems, except Pb and Cd. Translocation was most significant for Zn and Cd, but limited for Pb. Metal concentration in root and leaf was not proportional to that in the substrates, unexpectedly the minimum being observed in the mixed substrate whilst plant growth was retarded by 20% (38% on tailings). Calcium, pH, organic matter and phosphorus were the main influencing factors for metal translocation. The ultrastructure of V. faba L. cells changed a lot in the mine tailings group: root cell walls were thickened with electron dense Pb, Zn and C particles; in chloroplasts, the number of plastoglobuli increased, whereas the thylakoids were swollen and their number decreased in grana. Finally, needleshaped crystalline concretions made of Ca and P, with Zn content, were formed in the apoplast of the plants. The stratagems of V. faba L. undergoing high concentrations of toxic metals in carbonate substrate, suggest root cell wall thickening to decrease uptake of toxic metals, a possible control of metal transport from roots to leaves by synthesizing phytochelators-toxic metal complexes, and finally a control of exceeded Ca and metal concentration in leaves by crystal P formation as ultimate response to stress defense. The geochemical factors influencing metal availability, guaranty a reduction of metal content in plant growing on mixed tailing/soil substrate as far as carbon te are not completely dissolved.

“…Accumulation and exclusion are two basic strategies by which plants respond to elevated concentrations of HMs (Baker 1981). A TF (Cshoot/Croot) greater than 1 is common in metal accumulator species, whereas the TF is lower than 1 in metal excluder species (Baker 1981, Vogel et al 2005. The TFs (Cshoot/ Croot) and BFs (Cshoot/Csoil) of A. nepalensis for Zn and Pb were lower than 1 in soils severely polluted with Zn and Pb (P1, P2 and P3), indicating that exclusion might be its tolerance strategy.…”

“…A considerable variation in soil and plant metal concentrations both within and between the sampling plots was observed, reflecting the heterogeneous nature of the polluted area and high individual variability within plants (Vogel et al 2005, Unterbrunner et al 2007). Our results indicated that metals were mainly accumulated in the roots of A. nepalensis, particularly in those plots with high metal concentrations (Fig.…”

© iForest -Biogeosciences and Forestry IntroductionContamination of soil with zinc, lead and cadmium due to residues from metalliferous mining, smelting and other anthropic activities has attracted considerable attention in the past decade (Zhao et al. 2003). Because of the high toxicity of heavy metals (HMs) and their undegradable nature, metal pollution of soils has become one of the most serious environmental problems (Lee et al. 2009). In addition, heavy metals can be transferred to the food chain from the soil and seriously affect human health . First investigated by Chaney in 1983 , phytoremediation is a promising, ecologically-friendly approach to the remediation of contaminated soil using plants to remove toxic elements from the environment or render them non-toxic (Salt et al. 1998, Suresh & Ravishankar 2004. However, most plants are sensitive to excessive HMs in soil. In nature, only a small fraction of plants that exhibit metal tolerance or super-accumulative capacity (hyperaccumulators) can survive in toxic metal-contaminated soils, and the majority are herbaceous species with small biomasses (Sarma 2011). Woody plants or trees with developed root systems and large biomasses are especially attractive for revegetation and phytoremediation in metal-polluted sites (Lee et al. 2009, Capuana 2013. Additionally, exploring native plants with phytoremediation potential is a particularly important strategy, as indigenous plants are often more dependant in terms of survival, growth and reproduction under environmental stress than exotic plants (Yoon et al. 2006).Native to Pakistan, eastern Nepal, Bhutan, northern India, south-western China, upper Myanmar and parts of Indochina, A.nepalensis is a multipurpose alder species. Characterized by a series of merits such as fast growth and nitrogen fixation, its uses include commercial timber production of moderately soft wood and charcoal feedstock. Moreover, A. nepalensis is a chief associate in various commercial timber plantations, where it not only helps to raise the nitrogen levels of fields but also acts as a pioneer species on denuded habitats with freshly exposed soils, or rocky and eroded slopes in subtropical-totemperate belts of the Himalaya (Sharma & Ambasht 1984). Several other Alnus species have been surveyed to evaluate their phytoremediation potential for metal contaminated soils. For example, Rosselli et al. (2003) found that Alnus incana could be considered as an excluder of Zn, Cd and Cu. Mertens et al. (2004) found that Alnus glutinosa showed low foliar heavy metal concentrations and might therefore be suitable for phytostabilization purposes on polluted sites. Lee et al. (2009) also reported that Alnus hirsuta was a better candidate than Alnus firma for phytoremediation of HM-contaminated soils. However, there is no information about the potential of Alnus nepalensis to remediate Zn-, Pb-and Cd-contaminated soils.In the present study, the metal accumulation capacity of A. nepalensis growing in a lead and zinc mining spoil heap in Lancang county o...

“…Many plants, such as Thlaspi praecox Wulf., have exclusion strategies that prevent Pb from entering the plant. These plants can accumulate cadmium (Cd) and zinc (Zn) but exclude Pb from their tissues (Vogel-Mikus et al 2005). However, some plants such as Sesbania drummindii (Fabaceae), and some species of Brassicaceae (such as Brassica juncea (L.) Czern.)…”

-(Effectiveness of plant growth promoting rhizobacteria in facilitating lead and nutrient uptake by little seed canary grass). We investigated the effectiveness of Nitroxin inoculation on lead (Pb) and nutrient uptakes by little seed canary grass. The factors tested included inoculation (or not) with Nitroxin and different soil concentrations of Pb (0, 200, 400 and 800 mgPb kg -1 soil). Increasing soil concentrations of Pb decreased stem, leaf and root dry weights. Shoot phosphorus concentrations increased in parallel with increasing soil Pb concentrations. Nitroxin inoculation did not alter the phosphorus concentration of the roots. The Pb translocation factor was > 1 in inoculated treatments in the Pb soil concentration range of 200 to 400 mg kg -1 ; the translocation factor for 800 mgPb kg -1 with no inoculation of Nitroxin was, however, < 1. Our results indicated that the Pb bioaccumulation factor for little seed canary grass was < 1, indicating that it is a Pb excluding plant.
