Aided phytostabilization using Miscanthus sinensis×giganteus on heavy metal-contaminated soils

Metal accumulation and shoot yield of Miscanthus×giganteus growing in contaminated agricultural soils: Insights into agronomic practices

“…Also, the BCFs were higher in roots than in rhizomes, stems and leaves, suggesting that roots play a key role in reducing the metal transfer to the rhizomes and aboveground organs. Indeed, Miscanthus  giganteus is an excluder species suitable for phytostabilization (Nsanganwimana et al, 2014;Pavel et al, 2014;Pidlisnyuk et al, 2014). Moreover, apart from Cd, Pb, and Zn mean concentrations in non-senescent leaves (8.2-14.3 mg kg À1 and 53-68.2 mg kg À1 for Pb and Zn respectively) were more or less comparable with frequent concentrations in plants (Tlusto s et al, 2006).…”

Arbuscular mycorrhizal fungal inoculation protects Miscanthus×giganteus against trace element toxicity in a highly metal-contaminated site

“…Miscanthus is a rhizomatous perennial C4 grass that is known to be mycotrophic and is found in the field with arbuscular mycorrhizal fungi symbionts under acid sulfate soils and in metal-contaminated soils (Leung et al, 2007). Interest in Miscanthus is due to its various agronomic and economic characteristics, such as long life time, relatively low nutrient requirements and high mass yield per hectare reaching 17.7 t ha −1 y −1 (Christian et al, 2008;Nsanganwimana et al, 2014;Pavel et al, 2014). Miscanthus × giganteus plants grow on highly contaminated soils, reducing pollutant wind dispersion and immobilizing part of the contaminants by adsorption or root accumulation, which limits the transfer to aerial parts.…”

Heavy Metal Uptake by Novel Miscanthus Seed-Based Hybrids Cultivated in Heavy Metal Contaminated Soil

“…Papers concerning the cultivation of M. × giganteus in contaminated soil are widely available, however, there is a lack of information regarding heavy metal uptake by novel, seeds based hybrids. For example, Pavel et al [14] tested M. × giganteus capacity for aided phytostablisation of HM contaminated soil with concentrations of lead and cadmium similar to the presented study. They found that Miscanthus in the biomass harvested in spring, accumulated about 25 and 2 mg kg -1 of lead and cadmium, respectively.…”

“…relatively new on the market. Experiments involving the cultivation of commercial M. × giganteus in contaminated soils are widely described by many authors [10,11,14,19]. The aim of the current study was to assess the cultivation potential of novel Miscanthus seeds-based hybrids on heavy metal contaminated arable land, alongside M. × giganteus propogated from rhizomes.…”
