Cadmium induced changes on Growth, Lipid Peroxidation and Antioxidative Enzymes in the bioenergy crop, Ricinus communis L.
Journal Title: IOSR Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT) - Year 2018, Vol 12, Issue 8
Abstract
Ricinus communis L. plants were grown in soil having different concentrations of Cd (5, 20, 60 and120 mgkg-1) in a pot culture experiment. Plants were harvested after 60 days. The effects of Cd on biomass, leaf area, photosynthetic pigments, protein, antioxidative enzymes and proline were analysed. High Cd level in soil cause significant reduction in chl a, chl b, total chl and carotenoid. MDA content and activities of antioxidative enzymes viz., SOD, CAT and POD increased at high Cd concentration. SEM-EDX study showed Cd accumulation and deposition in the roots and leaf tissues. Highest accumulation of Cd was observed in the roots. Overall Cd had negative effects on the morpho-physiological characteristics of R. communis.
