“…The reason for this difference may be, on the one hand, that the soils of the three experimental fields are neutral and alkaline, which reduces the bioavailability of soil Cd, and on the other hand, LAWC-Cds were used in our study because it has a low enrichment capacity for soil Cd compared with high-Cd-accumulating wheat cultivars. Wheat roots, as the first organ exposed to soil Cd ions, are an important part of the absorption and storage compartment, and the enrichment capacity of roots for Cd is greater than that of stems and leaves [49]. Additionally, root uptake of Cd directly affects the level of Cd enrichment in wheat plants with low Cd accumulation.…”

Low-cadmium (Cd) accumulating wheat cultivars (LAWC-Cds) can effectively reduce the total Cd content in wheat grains (Grain-Cd). Thirteen LAWC-Cds were planted in three fields to study the enrichment, transport, and accumulation patterns of Cd in LAWC-Cds. Compared with the soil properties before planting, the soil pH and the total Cd content in the soil decreased, while the Cd content in the diethylenetriaminepentaacetic acid extract, soil conductivity, and soil organic matter increased at wheat maturity. The Cd enrichment capacity of the different organs of wheat decreased in the following order: root > leaf > rachis > stem > glume > grain. The dynamics of Cd accumulation in roots affected Grain-Cd, and these factors were negatively correlated. The Cd content and Cd accumulation in all organs of LAWC-Cds showed strong negative correlations with the lengths of the first and second internodes and highly significant positive correlations with both grains per spike and awn length. Structural equation modeling showed that the Cd content of wheat organs had the most direct effect (0.639) in determining Grain-Cd, and soil properties had the largest effect (0.744) in influencing Grain-Cd. This study is important for screening wheat cultivars with stable low Cd-accumulation characteristics.
