“…The results align with the work of Fernando and Oliveira [26] who demonstrated negative effects of metal-contaminated soils on tiller numbers per M. x giganteus plant. In the present study, the decline in plant growth may be an outcome of TE impacts on the main metabolic processes such as photosynthetic activities, respiration, as well as nutrient and water uptake [13].…”

“…The decline in amounts of the photosynthetic pigments Chlorophyll a, b (Chl a, b) and carotenoids (car) is another sign of the noxious effects on plants of TEs. This may happen either by inhibiting the activity of the enzymes involved in their biosynthesis or as a result of oxidative damage [13]. Secondary metabolites contribute to certain toxins, natural colours, tastes or even odours in plants [14], and play an essential role in defining the interactions these plants have with their surroundings and against different types of stress, including TEs.…”

Miscanthus × giganteus demonstrated good phytostabilization potentials in toxic element (TE) contaminated soils. However, information about its tolerance to elevated concentrations is still scarce. Therefore, an ex-situ pot experiment was launched using three cultivars (termed B, U, and A) grown in soils with a gradient Cd, Pb and Zn concentrations. Control plants were also cultivated in non-contaminated soil. Results show that the number of tillers per plant, stem diameter as well as leaf photosynthetic pigments (chlorophyll a, b and carotenoids) were negatively impacted by soil contamination. On the other hand, phenolic compounds, flavonoids, tannins, and anthocyanins levels along with the antioxidant enzymatic activities of superoxide dismutase, ascorbate peroxidase and glutathione reductase increased in the plants grown on contaminated soils. Altogether, these data demonstrate that miscanthus is impacted by concentrations of toxic elements yet is able to tolerate high levels of soil contamination. These results may contribute to clarifying the miscanthus tolerance strategy against high contamination levels and its efficiency in phytoremediation.

“…It is noteworthy that M × g grown in heavy metal contaminated soil over a long period of time would suffer from early aging of leaves, retarded growth, and lower biomass yield. Fortunately, the application of mineral fertilizers (i.e., N:P:K = 15:15:15) can substantially alleviate these symptoms and significantly increase chlorophyll a content, photosystem II efficiency, and ultimately biomass yield (Andrejic et al., 2019).…”

“…Miscanthus × giganteus (M. × giganteus) is a promising second-generation energy crop [10,11] that showed the ability to grow in marginal and contaminated lands [12][13][14][15]. It is a rhizomatous, lignocellulose-rich perennial grass grown worldwide as a source of energy or bio-based products [16,17].…”

Dynamic of Morphological and Physiological Parameters and Variation of Soil Characteristics during Miscanthus × giganteus Cultivation in the Diesel-Contaminated Land

et al. 2021

Miscanthus × giganteus (M. × giganteus) is a perspective plant produced on marginal and contaminated lands with biomass used for energy or bioproducts. In the current study, M. × giganteus development was tested in the diesel-contaminated soils (ranged from 250 mg kg−1 to 5000 mg kg−1) and the growth dynamic, leaves quantity, plants total area, number of harvested stems and leaves, SPAD and NPQt parameters were evaluated. Results showed a remarkable M. × giganteus growth in a selected interval of diesel-contaminated soil with sufficient harvested biomass. The amendment of soil by biochar 1 (produced from wastewater sludge) and biochar 2 (produced from a mixture of wood waste and biohumus) improved the crop’s morphological and physiological parameters. Biochar 1 stimulated the increase of the stems’ biomass, while biochar 2 increased the leaves biomass. The plants growing in the uncontaminated soil decreased the content of NO3, pH (KCl), P2O5 and increased the content of NH4. Photosynthesis parameters showed that incorporating biochar 1 and biochar 2 to the diesel-contaminated soil prolonged the plants’ vegetation, which was more potent for biochar 1. M. × giganteus utilization united with biochar amendment can be recommended to remediate diesel-contaminated land in concentration range 250–5000 mg kg−1.
