چکیده انگلیسی
Tuber cadmium (Cd) accumulation was evaluated in ten potato cultivars grown in the same field with an average soil Cd level of 0.06 mg kgâ1 dry weight (DW). Analysis of tuber metal levels revealed a significant difference in mean Cd concentrations among different cultivars, which varied from 0.05 to 0.21 mg kgâ1 DW. No cultivars exceeded the maximum permissible concentration (MPC) for Cd in potato. Correlation analysis showed a strong positive relationship between bioaccumulation of Cd and zinc (Zn), copper (Cu) or manganese (Mn). There was also a negative correlation between Cd and iron (Fe) accumulation which was significant only within three cultivars including Summer Delight, Russet Burbank and Agria. Summer Delight, with the lowest Cd and highest Fe content, was identified as a low Cd accumulating cultivar as well as a Fe-enriched tuber vegetable making it of significant interest. Laura, Yukon Gold and Purple Passion were identified as strong Cd accumulators. One of the implications is that growing these three potato cultivars in soils with Cd levels greater than 0.06 mg kgâ1 DW might be of human health concern.
