Giant Rice Is a Unique Candidate for the Sustainable Phytoremediation of Cadmium-Contaminated Paddy Fields.

ABSTRACT: The limited availability of ideal cadmium (Cd) hyperaccumulating plants remains a significant challenge for phytoremediating Cd-contaminated soils. This study aims to find out if the high biomass giant rice can be a suitable phytoremediation candidate for Cd-contaminated paddy fields and to elucidate physiological mechanisms relative to low or high Cd accumulation. Soil column and lysimeter tests were conducted with giant and normal species of rice under different water conditions. Cd distribution in different parts of root and shoots were determined. Under sustained flooding in column tests or keeping soil moist after the tillering stage in lysimeter tests, Cd contents in the grain of giant rice were very low. The Cd bioconcentration factor (BCF) of grain of giant rice (0.015-0.034) were
