Estimation of Barium Toxicity Mitigating Efficacy of Amaranthus caudatus L.

Journal Title: Universal Journal of Environmental Research and Technology - Year 2015, Vol 5, Issue 6

Abstract

Barium commonly used in the fireworks – cottage industry of this area is the predominant pollutant on growth, biochemical and enzymatic characteristics of Amaranthus caudatus L. a widely cultivated crop. This study is aimed at assessing the efficacy of Amaranthus caudatus L.in the absorption of barium. The seedlings of Amanranthus caudatusL. were treated with various concentration of barium (2mM, 4mM, 6mM, 8mM, 10mM) and its effect on the morphometric, biochemical and enzymatic characters were studied. After ten days of treatment the growth parameters such as leaf area, fresh weight, dry weight, shoot and root length were found decreased than in the control. Biochemical characteristics such as the content of chlorophyll, carotenoid, soluble sugar and protein also decreased with the increase in the concentration of barium. In contrary, the free amino acid, proline, and leaf nitrate increased and the activities of enzymes such as catalase and peroxidase were also found to be increased with the increase in the concentration of barium while the activity of nitrate reductase was found decreased. The result suggest that comparison of the parameters analyzed between the treated and control reveals that barium has seriously affected the Amaranthus caudatus L. but at the same time the plant adopts mechanisms such as accumulation of anthocyanin and enhanced activities of antioxidant enzymes to overcome the ill effects of the metal ions. Thus this study is unique in the sense that, this plant Amaranthus caudatus L. having been found to be huperaccumulative of metals can be Co-cultivate along with plants susceptible to metal toxicity to overcome the problem of metal toxicity to plants.
