Selenium Decreases the Cadmium Content in Brown Rice: Foliar Se Application to Plants Grown in Cd-contaminated Soil

Abstract Cadmium (Cd) contamination in agricultural soils has become a serious issue owing to its high toxicity threat human health through the food chain. The purpose of this paper is explore availability foliar selenium (Se) application reducing Cd enrichment brown rice. A field experiment from 2017 2019 was conducted investigate effects Se on physiology and yields three rice cultivars their accumulation low-Cd high-Cd soils. grain protein contents plants grown soil were lower than those cultivated by 27.85% 6.82%, whereas malondialdehyde (MDA) higher 66.06% 91.47%, respectively. reduced translocation stems leaves spikes, decreasing content 40.36%. Additionally, enhanced antioxidative activity, glutathione contents, yield (7.58%) decreased MDA proline contents. However, these weakened under soil. Foliar can alleviate Cd-induced physiological stress while improving content.
