It must be noted that Cr is, a toxic and nonessential element to plants, and hence, the, plants may not possess any specific mechanism of, Chromium stress can induce three possible types of, the production of pigments which are involved in the life, sustenance of plants (e.g., chlorophyll, anthocyanin) (, metabolites (e.g., glutathione, ascorbic acid) as a direc, response to Cr stress which may cause damage to the plants, channelise the production of new biochemically related, metabolites which may confer resistance or tolerance, stress (e.g., phytochelatins, histidine) (, Nitrate reductase (NR) activity of leaves was signifi-, cantly increased over control values and negatively corre-, lated with root and shoot length, leaf area and biomass of, the plants, indicating stress due to Cr(VI) in, resulted in significant inhibition of NR activity in, resulted in increased NR activity, whereas higher Cr, concentrations were toxic and reduced the enzyme activity, Chlorosis induced by heavy metals has been generally, correlated with low plant Fe content, suggesting. McAuley A, Olatunji MA. Among phosphate-solubilizing microorganisms, it has been reported that mycorrhizal fungi have the ability to actively mobilize and translocate nutrients from minerals and soil organic matter, directly to their host plant.

The toxic effects appeared at 1ppm concentration of Cr and 4ppm chromium concentration appeared lethal dose to sorghum. are secreted by roots and act as a source of food for soil microbes especially for The, significantly higher toxic effect of Cr(VI) in decli, stomatal conductance could be due to the high, potential of Cr(VI), which in turn may be instrumental in.

A pot experiment was performed to study biomass production and leaf ionome composition of five herbaceous species (Achillea millefolium, Bromus erectus, Festuca arundinacea, Melilotus officinalis and Medicago sativa), in relation to soil pore water's pH, concentration of trace and major elements and their chemical speciation.
