Abstract This study aimed to examine the influence of increasing doses of chromium (Cr) (26, 39, and 52 mg kg−1 soil) and elemental sulfur (S) (60 mg kg−1 soil) on growth, yield, and mineral nutrition in wheat and maize. Macro- and micronutrients and Cr concentrations were determined in the aboveground parts of plants. All examined doses of Cr caused a marked decrease in the fresh and dry weight of maize. Wheat was more tolerant than maize, and lower Cr doses caused a small but statistically significant increase in the total yield. Wheat accumulated more than twofold Cr than maize, and the concentrations increased with higher Cr concentrations in the soil. The application of S significantly improved the total biomass production and lowered the Cr content in both plants. Cr changed the mineral nutrition in both cereals, but the pattern of changes observed was not the same. Applying S alleviated some adverse effects caused by the Cr. Hence, it is concluded that the application of elemental S may be an effective strategy to reduce adverse effects in plants grown on soil contaminated by heavy metals, especially Cr.

施硫可减轻玉米和小麦的铬胁迫

摘要 本研究旨在检查增加铬 (Cr)（26、39 和 52 mg kg-1 土壤）和元素硫（S）（60 mg kg-1 土壤）剂量对生长、产量和矿物质的影响。小麦和玉米的营养。测定了植物地上部分的常量和微量营养素以及 Cr 浓度。所有检查剂量的 Cr 都导致玉米的鲜重和干重显着下降。小麦比玉米更耐受，较低的铬剂量导致总产量的小幅但具有统计学意义的增加。小麦积累的 Cr 是玉米的两倍以上，并且随着土壤中 Cr 浓度的升高，该浓度增加。S的施用显着提高了两种植物的总生物质产量并降低了Cr含量。Cr 改变了两种谷物中的矿物质营养，但观察到的变化模式并不相同。应用S减轻了Cr引起的一些不利影响。因此，可以得出结论，元素硫的应用可能是一种有效的策略，可以减少对生长在被重金属，尤其是铬污染的土壤上的植物的不利影响。
