“…Moreover, trace metals generally reduce plant growth, with special reference to Cd, which significantly reduced leaf number, inter nodal distance, plant height and root length (Hadi et al 2010). Barbosa et al (2015) found that the different concentrations of Zn, Cr, and Pb in soils reduce biomass aerial production of A. donax.…”

Arundo donax L. has a high biomass production and a tendency toward community dominance in many habitats and thereby a tolerance to a wide range of environmental conditions. Therefore, the present study investigated the potentiality of A. donax to accumulate nutrients and trace metals in its biomass. Six main habitats (Nile Bank, Drain Bank, Canal Bank, Field Edges, Railways and Roadsides) were recognized. At each habitat, six quadrats (each 1 m(2)), distributed equally in two sites, were selected for growth measurements (e.g., density, shoot height, diameter, leaf area and biomass), plant and soil analyses. Plants from Nile, Canal and Drain Banks had the highest values of most growth measurements, while those from Railways and Roadsides had the lowest. Canal Bank plants accumulated the highest concentrations of P, Cu and Pb in their leaves; Zn in the stem; and Mg, Cd and Fe in the rhizome. The bioaccumulation factor (BF) of A. donax, for Cd, Fe, Mn and Zn, was greater than 1, while the translocation factor (TF) of most trace metals was less than unity in most habitats. In conclusion, A. donax showed morphological plasticity in response to habitat heterogeneity, and its growth was most vigorous in the riparian habitats. The high BF, as well as the significant positive correlations between trace metals, especially Cd, in soil and plant, renders A. donax a powerful phytoremediator.

“…Although similar zinc concentrations in the roots and shoots as Sun et al (2007) confirmed also for of Arundo donax and Miscanthus spp. Barbosa et al (2015), their results divide upon prefer place of Zn accumulation. Barbosa et al (2015) introduce equally to us (Table 3) higher Zn concentration in the roots.…”

“…Barbosa et al (2015), their results divide upon prefer place of Zn accumulation. Barbosa et al (2015) introduce equally to us (Table 3) higher Zn concentration in the roots. While negative correlation was observed between roots and shoots Zn accumulation and root and shoot growth (Table 7), highly positive correlation between roots and shoots growth (r = 0.935; p < 0.01), and roots and shoots fresh mass (r = 0.997; p < 0.01) was confirmed.…”

Phytotoxicity of Se(IV), Se(VI), Cu and Zn to Sinapis alba L. seedlings was expressed by inhibition of selected physiological processes (root and shoot growth, fresh and dry biomass production, water content) and correlated with their bioaccumulation. Roots growth was inhibited more than that of shoots and only Se(IV) reduced also shoots growth (IC 50 = 25.8 mg L -1 ). Se(VI) decreased more roots (IC 50 = 23.6 mg L -1 ) than shoots growth (IC 50 = 461.4 mg L -1 ). Phytotoxicity to roots growth increased as follows: Zn < Se(VI) ≅ Cu < Se(IV). All metals, except Cu, decreased more roots and shoots fresh mass than that of dry mass. Water content was for all (semi)metals more depressed in shoots, however, for Zn any significant changes in roots WC were confirmed. In any case transportation index Ti overreached value 1 and that indicate metals storage in the roots; however, for control the opposite results were obtained. While the highest bioaccumulation factor (BAF) was determined for Cu in both roots (1.016) and shoots (0.271) the lowest values for this parameter were confirmed for Se(VI) in the roots (0.061) and for Se(IV) in the shoots (0.010). While in the control Cu, Se and Zn content was higher in the shoots, treatment with these metals increased their accumulation mainly in the roots. Statistically negative correlation was confirmed among Se(IV), Se(VI) and Cu accumulation in the roots and water content in the roots, and among Se(IV) and Cu accumulation in the roots and water content in the shoots.

“…For evaluating the potential of plants as well as the effect of microbial inoculations on plant tolerant at different levels of Pb contamination, the relative plant dry matter yield was calculated by dividing the dry biomass of plant in each treatment ( Y c ) by dry biomass in the control treatment at Pb 0 mg kg −1 (without Pb in non‐inoculated treatment) of the soil ( Y 0 ):

RY = \frac{Y c}{Y_{0}}

Microbe‐assisted phytoremediation is a promising technology for remediation of potentially toxic element contaminated soils. A greenhouse study was conducted to assess the effect of Pseudomonas spp. and Glomus spp. on phytoremediation of a Pb‐contaminated calcareous soil by Centaurea cyanus L. The study was carried out as a factorial experiment arranged in a randomized complete block design with three replications. Factors are microbial inoculation in three levels (mix inoculation with Glomus spp. or Pseudomonas spp. and non‐inoculated) and four Pb concentrations (0, 250, 500, and 1000 mg kg−1) in soil. The results revealed that microbial inoculation significantly increased the shoot dry weight and Pb accumulation in C. cyanus compared to non‐inoculated plants. Comparison of microbial treatments indicated that higher shoot Pb concentration, shoot modified bioconcentration factor (shoot mBCF, 5.33–5.63) and translocation factor (TF, 1.09–1.2) are obtained for Pseudomonas spp. inoculation, while higher plant biomass, plant Pb accumulation, root Pb concentration, root mBCF (5.91–6.46) and lower TF (0.77–0.99) are recorded for Glomus spp. inoculation. These results show that Pseudomonas spp. and Glomus spp. are more effective in phyotoextraction and phytostabilization of Pb by C. cyanus, respectively. It could be concluded that Pseudomonas spp. and Glomus spp. would be a promising strategy in bioremediation of Pb‐contaminated soils, especially at medium levels of soil Pb contamination (250 and 500 mg kg−1).
