Effect of bioaccumulation of cadmium on biomass productivity, essential trace elements, chlorophyll biosynthesis, and macromolecules of wheat seedlings

摘要: Soil contamination with heavy metals has become a worldwide problem, leading to losses in agricultural yield and hazardous human health effects as they enter the food chain. The present investigation was undertaken examine influence of cadmium (Cd2+) on wheat (Triticum aestivum L.) plant. Cd2+ accumulation distribution 3-wk-old seedlings grown nutrient medium containing varying concentrations (control, 0.25, 0.50, 1.0, 2.5, 5.0 mg/L) monitored. effect up 21 d biomass productivity, plant growth, photosynthetic pigments, protein, amino acids, starch, soluble sugars, essential nutrients uptake studied detail explore level which can withstand stress metal. Plants treated 0.5, mg/L showed symptoms heavy-metal toxicity observed by various morphological parameters were recorded growth plants. root, shoot-leaf length progressively decreased increasing concentration medium. found be maximum during initial period. also interfered uptake, especially calcium (Ca2+), magnesium (Mg2+), potassium (K+), iron (Fe2+), zinc (Zn2+), manganese (Mn2+) from Growth reduction altered levels major biochemical constituents such chlorophyll, free sugars that play role metabolism response In study, mineral nutrients, chlorophyll biosynthesis, acid, plants estimated establish an overall picture at structural functional levels.
