Indoor experiments were performed to determine the accumulation, subcellular distribution, and chemical forms of Cd at five S levels in Hydrilla verticillata. The Cd content increased from 1.229 mg/g to 3.329 mg/g in leaves, and decreased from 2.794 mg/g to 1.023 mg/g in roots, respectively. Excess S supply stimulated Cd assimilation in leaves as Cd accumulation was inhibited in roots. The Cd content...
We investigated the effects of high-productivity plant hybrid giant Napier (HGN)-derived biochars prepared at different pyrolysis temperatures on Cd migration in a soil-cabbage system contaminated with Cd and butachlor. The results showed that with the enhancement amount of biochar applied, soil pH and electrical conductivity (EC) increased, whereas the available Cd content dropped significantly (P<0...
Two rice varieties, one perchlorate-tolerant (Gannuoxiang, GN) and the other perchlorate-sensitive (IR65598-112-2, IR), were exposed to 20, 200, and 400 mg/kg soil perchlorate to investigate their physiological responses and perchlorate accumulation. It was found that perchlorate decreased leaf chlorophyll content in both rice varieties. The activities of superoxide dismutase (SOD) and catalase (CAT)...
