Pot experiments were conducted to investigate the difference in arsenic (As), cadmium (Cd), and phosphorus (P) uptake, accumulation, and translocation among 12 wheat cultivars and their relationships with each other in soil "naturally" contaminated with both As and Cd. As, Cd, and P concentrations in wheat grain, straw, and root differed significantly (p < 0.05) among the 12 wheat cultivars. The grain As concentration was not correlated with straw and root As, or the total As content in plants, but was significantly (p < 0.05) correlated with As translocation factors (TFs), i.e., TFs((Grain/Root)) and TFs((Grain/Straw)). The grain Cd concentration was positively correlated with the total Cd content and TFs((Grain/Straw)). The grain P concentration was positively correlated with straw and root P. Both As and Cd concentrations in wheat grains were correlated with P in wheat straw and grain. Compared with As, Cd was more easily transported to the wheat grain, and the rachis played a key role in ensuring this difference. A significant positive correlation was observed between root As and Cd, but no significant relationship was detected between grain As and Cd concentrations. The lack of a relationship between grain As and Cd suggests the possibility of selecting cultivars in which little As and Cd accumulation occurs in the wheat grain. (C) 2015 Elsevier B.V.
