Effects of cadmium and arsenic on growth and metal accumulation of Cd-hyperaccumulator Solanum nigrum L.

Genetic Variability of Barley (Hordeum vulgare L.) Genotypes in Phytoremediation of Heavy Metals-Contaminated Soil

“…We suggest using barley as hyperaccumulator; however, using any plant as hyperaccumulator of heavy metals needs to be precedent by evaluating the total content of heavy metals and both bio-accumulation and translocation factors (Sun et al, 2008). Therefore, further investigations and analyses are needed to support our study in the future.…”

“…On the other hand, other studies suggested that other plant species might be more appropriate for phytoremediation, e.g. sorghum and Solanum nigrum and other wild plant species (Sun et al, 2008;Brunetti et al, 2009 andAngelova et al, 2011). …”

“…Wild species may be a candidate of being hyperaccumulator; nevertheless, both the bio-concentration (Brooks, 1998 andCluis, 2004) and translocation factors (Wei & Zhou, 2004a, b) need to be taken into consideration (Sun et al, 2008).…”

Effect of Cadmium on DNA Changes in Ipomoea aquatica Forssk.

“…The bioconcentration factor (BCF) was calculated as the ratio of the Cd concentration in the plant root to that in the soil, whereas the translocation factor (TF) was calculated as the ratio of the Cd concentration in the plant shoot to that in the root [14]. Cd-hyperaccumulating plants were defined based on the following standards: 1) accumulation capability corresponding to a threshold shoot metal concentration greater than 100 mg/kg shoot dry weight, 2) a BCF index greater than 1.0, sometimes reaching 50-100, 3) a TF index used to measure a plant's ability to translocate metal from the roots to the shoots [15][16][17], greater than 1.0. A GTS test was performed using the following equation: GTS (%) = (1-a/n) × 100, where 'a' is the number of polymorphic bands detected in each treated sample and 'n' is the number of total bands in the control [9].…”

Effectiveness of plant growth promoting rhizobacteria in facilitating lead and nutrient uptake by little seed canary grass

“…Tang et al (2009) reported that the TF of Arabis paniculata was < 1 in the range of Pb concentration between 9 and 296 μmol. Sun et al (2008Sun et al ( , 2009 showed that the TF of black nightshade (Solanum nigrum L.) was > 1, while Rezvani & Zaefarian (2011) reported that the TF of Aeluropus littoralis changed with differing soil Pb concentrations.…”
