“…Among other reasons, this is caused by an imbalance in micronutrient status (Shanker et al, 2005). The Fe accumulation was reduced in leaves in presence of Cr(III) or Cr(VI) in B. oleracea (Pandey & Sharma, 2003), Spinacia oleracea (Chatterjee & Chatterjee, 2000) or Zea mays (Mallick et al, 2010). Concentrations of other micronutrients, such as Cu, Zn and specially Mn, were greatly affected.…”

Chromium released into the environment from industrial activities has become an important environmental concern. Silene vulgaris has been proven to be tolerant to many heavy metals, so it is considered an interesting species in the revegetation and restoration of polluted soils, but no information is available about its response to Cr. The objective of this work was to study uptake and influence on plant growth of Cr(III) and Cr(VI) in six genotypes (four hermaphrodites and two females) of S. vulgaris from different sites of Madrid (Spain). Plants were treated for 12 days with 60 µM of Cr(III) or Cr(VI) in semihydroponics. Dry weights, soil-plant analysis development values (SPAD) reading with chlorophylls and micronutrient and total Cr concentrations were determined. Metal uptake was higher in presence of Cr(VI) than of Cr(III) and poorly translocated to the shoots. In both cases S. vulgaris did not show visual toxicity symptoms, biomass reduction, or differences among SPAD values as consequence of Cr additions. However genotypes SV36 and SV38 showed Fe and Mn imbalance. This is the first report on the relatively good performance of hermaphrodite and female S. vulgaris genotypes in Cr uptake and physiological traits, but further studies will be necessary to elucidate the mechanisms by which the gender may influence these variables. S. vulgaris presented high diversity at genotypic level; the treatment with hexavalent Cr increased the differences among genotypes so the use of cuttings from an homogeneous genotype seems to be an adequate method for the study of this species.

“…Metals such as lead (Pb), cadmium (Cd), chromium (Cr), and copper (Cu) may inhibit certain essential physiological activities (Foy et al 1978). Pandey and Sharma (2003) showed that Cr treatment decreased the Fe concentration in cabbage leaves. High levels of Cu are also known to inhibit metabolic activities such as germination, root, leaf and stem growth and photosynthesis, biomass, and the pigment content (Foy et al 1978, Pandley and Sharma 2003, Shanker et al 2005, Mallick et al 2010.…”

Effects of interactions between high temperature and chromium (Cr(VI)) and copper (Cu) on wheat (Triticum aestivum L. cv. Dagdas 94) seedlings were investigated. High concentrations of Cr and Cu at 40°C decreased the root and shoot length and dry weight. The total chlorophyll content was decreased at 30 µM Cr + 40°C. At the high Cr and Cu concentrations, carotenoid content was increased compared to that of control groups. Heavy metal treatment increased proline content but decreased that of soluble protein. In addition, chromium showed greater toxic effects on growth and biochemical parameters than that of Cu.

“…Being a heavy metal, Cr is a potential agent of oxidative stress, inducing oxidative damage to lipids, proteins and DNA-like biomolecules (Shanker et al, 2004). Cr changes in activity of antioxidant enzymes as well as of other enzymes in order to disrupt the nutrients and water balance (Pandey and Sharma, 2003). It is also reported that it could stimulate the formation of free radicals and reactive oxygen species (ROS) such as superoxide radicals (O 2 -), hydrogen peroxide (H 2 O 2 ) and the hydroxyl radical (·OH).…”

Two maize varieties, viz. Sartaj and Deccan, have been evaluated according to their responses to chromium (Cr) in terms of specific physiological and biochemical attributes. During the exposure to Cr concentration (0, 50, 100, 200 and 300 µM) of potassium dichromate (K 2 Cr 2 O 7 ) for seven days, significant changes of oxidative stress in terms of lipid peroxidation and protein oxidation were recorded along with other antioxidative pathways. It is revealed that irrespective of varieties, Sartaj was more prone to oxidative stress since the amount of superoxide due to Cr exposure was found to be significant, unlike the second variety, Deccan. In addition, for Sartaj the activity of NAD(P)H oxidase recorded a significant linear increase in a dose response manner.The changes of antioxidative enzymes recorded significant variation in both varieties under stress compared to control. However, Deccan maintains a consistent up regulation in SOD and GPX activities. Contrarily, APX activity was less sensitive to both varieties. The activation of antioxidative mechanisms due to the impact of Cr-induced oxidative stress has been described subsequently. The results deriving from this investigation might be effective for the selection of tolerant plant types under chromium contamination.
