Effects of soil properties on accumulation characteristics of copper, manganese, zinc, and cadmium in Chinese turnip
Clarifying the mechanisms of heavy metal (HM) accumulation and translocation from soil-root-leaf is crucial to coping with soil HM pollution. In this study, we analysed copper (Cu), manganese (Mn), zinc (Zn) and cadmium (Cd) accumulation characteristics in Chinese turnips and the effect of soil phys...

Clarifying the mechanisms of heavy metal (HM) accumulation and translocation from soil-root-leaf is crucial to coping with soil HM pollution. In this study, we analysed copper (Cu), manganese (Mn), zinc (Zn) and cadmium (Cd) accumulation characteristics in Chinese turnips and the effect of soil physicochemical properties on both HM accumulation and translocation. Our results indicate that Chinese turnips absorb and translocate Mn, Zn, and Cd at much higher levels than they do Cu. When we measured bioconcentration factors in Chinese turnips for different HMs in the same soil, we found Chinese turnip capacities for HM accumulation decrease from Zn > Mn > Cd > Cu. In addition, the translocation factor for these HMs decreases from Mn > Cd > Zn > Cu. Correlation analysis indicates that soil pH and various soil components are either negatively or positively correlated with Mn, Zn, and Cd accumulation; also, soil properties are correlated with Mn translocation from root to leaf. These findings may help evaluate HM accumulation and translocation mechanisms as well as artificially regulate HM uptake levels from soils to turnips.
