In durum wheat, Harris and Taylor (2004, 2013) showed that differences in grain Cd concentration between two near-isogenic durum wheat lines were attributable to differences in the partitioning of Cd between organs rather than to total Cd uptake differences.

Cadmium Toxicity in Plants and Role of Mineral Nutrients ...

Cadmium (Cd) is a toxic heavy metal that enters the environment through various anthropogenic sources, and inhibits plant growth and development. Cadmium toxicity may result from disturbance in plant metabolism as a consequence of disturbance in the uptake and translocation of mineral nutrients.

At maturity, total Cd-uptake increased linearly with supply in Creso, from 13 to 23 μg/plant, and was approximately 18 μg/plant, irrespective of Cd level, in Svevo. Partitioning to shoot was higher in Svevo than in Creso, both at heading and maturity.

Background. Concentrations of cadmium (Cd) in the grain of many durum wheat (Triticum turgidum subsp. durum) varieties grown in North American prairie soils often exceed international trade standards.Genotypic differences in root-to-shoot translocation of Cd are a major determinant of intraspecific variation in the accumulation of Cd in grain.

Since varieties differ markedly in grain-Cd accumulation, efforts are needed to find traits associated with low, or high, accumulation. Two durum wheat varieties, selected in a field screening as low (Creso) and high (Svevo) grain-Cd accumulating, were grown on soil spiked with 1.5, 3 and 4.5 mg Cd/kg.
