“…4 showed a remarkable higher Tf in control plants, where Ni concentration in roots depended only on the seed supply, compared to that of plants treated with different Ni concentrations. This result was consistent with Galardi et al (2007), even if in that work the ratio between Tf of control plants and that of Nitreated plants was far lower than that found in our experiment. Among Ni-treated plants, a higher Tf was calculated in plants exposed to 150 µM NiCl 2 .…”

“…Among Ni-treated plants, a higher Tf was calculated in plants exposed to 150 µM NiCl 2 . The Tf values observed for A. paniculatus in this experiment are notable lower than those calculated from data reported by Galardi et al (2007) in different ecotypes of Alyssum bertolonii, a Ni-hyperaccumulator plant, exposed to Ni in similar experimental conditions. In control plants, the highest Tf can be ascribed to the physiological Ni demand of shoots to sustain leaf metabolic functions, such as enzyme activities and photosynthetic reactions.…”

“…An ability to concentrate Ni more than 30 fold from the nutrient solution was observed in A. paniculatus plants exposed to 25 and 50 µM NiCl 2 . However, this value is on average near ten fold lower than that reported in Ni-hyperaccumulating plants (Galardi et al, 2007).…”

Abstract.To evaluate a possible utilization in the phytoremediation of metal contaminated substrates, Amaranthus paniculatus L. plants were grown for one week in Ni-spiked growth solutions at 0, 25, 50, 100, 150 µM NiCl 2 in hydroponics under controlled climate conditions. Results showed a high tolerance to Ni in plants exposed to low Ni concentrations. Tolerance decreased as Ni concentration in the growth solutions enhanced. Ni concentrations in plant organs (root, stem and leaves) revealed a trend to increase in parallel with the enhancement of Ni content in the growth solution. The ability to accumulate Ni in plants was also evaluated by calculating the bioconcentration factor (BCF). An inverse relation between BCF and Ni concentrations in the growth solution was evidenced. Ni phytoremoval ability of A. paniculatus plants was particularly appreciable at 25 µM NiCl 2 , where more than 65% of the initial Ni amount was taken up by plants in one week of treatment. The capability of plants to translocate Ni from roots to shoots (stem+leaves) was evaluated by the translocation factor (Tf). Results revealed a low Tf in plants exposed to low Ni concentration, suggesting a tolerance mechanism to protect physiological processes occurring in leaves. Overall, A. paniculatus plants showed a valuable capability to phytodecontaminate Ni-polluted waters, particularly at low Ni concentrations.

“…It is worth pointing out that various parameters, such as season, temperature gradient and watering regime, length of day/night periods and viability of seedlings will affect the total uptake of nickel, and some variation in the final amount of a metal extracted is common even within the same family of plants. For example, intra-specific differences in tolerance and accumulation of nickel have been observed for nine outcrops of Alyssum bertolonii grown under hydroponic conditions (Galardi et al 2007). …”

“…Populations of Stanleya pinnata have been shown to vary in Se concentration depending on the population tested; these differences appear to be fixed based on common garden experiments (Feist and Parker 2001). Substantial population-level variation was also found for Ni accumulation in the Ni hyperaccumulator Alyssum bertolonii (Galardi et al 2007). The Cd hyperaccumulator Sedum alfredii also has fixed ecotypic differences including differences in Cd sequestration (Tian et al 2011) and translocation (Lu et al 2008).…”
