“…The degree of soil contamination and cultivar diversity greatly influence the yield of rapeseed [33]. At the Tangshi remediation base, the 15 winter rapeseed cultivars successfully overwintered and completed their life cycles, indicating that they had some resistance to Cd and Pb contamination [34]. Compared to the conventional yield data presented in Table 1, the seed yield of 11 rapeseed cultivars decreased, whereas that of the other four cultivars increased.…”

To determine the feasibility of planting rapeseed to safely utilize heavy metals (HMs)-contaminated farmlands surrounding working smelters under atmospheric deposition, a field trial was conducted to analyze the yields, cadmium (Cd) and lead (Pb) concentrations, health risks, and economic benefits of 15 rapeseed cultivars (13 Brassica napus L. and two Brassica campestris L.) in Jiyuan City, Henan Province, China. The results show that the seeds’ Cd concentration was 0.12–0.64 mg·kg−1 and the seeds’ Pb concentration was higher than Cd at 0.49–1.22 mg·kg−1. The Cd bioconcentration factor of B. campestris (0.702–0.822) was higher than that of B. napus (0.246–0.502). Additionally, Cd and Pb transfer factors from the stems to the pods and seeds were 0.34–1.20 and 0.54–4.53, respectively. Combined with a comprehensive analysis of the annual deposition data of Cd and Pb, 16.40 and 345.79 kg·hm−2, respectively, HMs in the seeds were not only derived from those in the soil, but were also derived from the atmosphere. Furthermore, the Cd and Pb levels in rapeseed oil, meal, and straw met the requirements stipulated in the standards for food safety, feeds hygiene, and organic fertilizer in China. Rapeseed–maize rotation yielded a profit of 15,550 CNY·a−1·hm−2, thereby increasing the economic output by 133.8%. A cluster analysis revealed that B. campestris SYH and ZS100 and B. napus ZY-821 showed the greatest comprehensive benefits. In conclusion, rapeseed cultivation is a viable and extendable approach that can achieve the safe utilization of typical HMs-contaminated farmland caused by atmospheric deposition in Northern China.

“…Bioremediation is an ecologically neutral technology that utilizes green plants and microorganisms to restore contaminated sites to their original state [210]. Oil crops like rapeseed and sunflowers are commonly used for phytoremediation of HM-contaminated soil due to their well-developed roots, large shoot biomass, and strong stress resistance [211][212][213]. Plants remediate HM-contaminated soil through the mechanisms encompassing accumulation, stability, volatilization, and degradation [214,215].…”

Oil crops are the second most cultivated economic crop in the world after food crops, and they are an important source of both edible and industrial oil. The growth of oil crops is limited by biotic and abiotic stresses, which hinder their yield and quality. Among all the agronomic measures, plant growth promoting bacteria (PGPB) play a crucial role in improving the yield, quality, and adaptability of oil crops. In this review, we considered the recent research on the sources of beneficial bacteria and their interactions with and influences on host plants, with a focus on summarizing the important roles and molecular mechanisms of PGPB in promoting growth and resisting biotic and abiotic stresses in oil crops. Finally, we outlined the current opportunities and challenges of microbial strategies for the improvement of the yield, quality, and adaptability of oil crops, providing a theoretical basis for the future use of microbial inoculants in these crops.

Phytoremediation can be accelerated if contaminated soils are amended with releasing agents. We tested four such materials, citric acid (CA), EDTA, oxalic acid (OA), and tartaric acid (TA) at two doses, 20 and 40 mmol kg−1, amended in a pot experiment to a heavily contaminated soil cultivated with purslane (Portulaca oleracea). We found that Cd extracted with DTPA remained unchanged in all treatments compared to the control except for the treatment of added EDTA at 40 mmol kg−1 (“EDTA-40”). Similar was the case with Cu, Pb, and Zn. As a consequence, Cd in the aboveground plant material increased significantly from 1.21 (control) to 3.84 at EDTA-40 and 3.55 at EDTA-20 (mg kg−1). Similar was the case with all other metals, with Pb exhibiting an impressive fivefold increase to 280.35 mg kg−1 at EDTA-40 from the control. We conclude that EDTA was the most successful releasing agent among those tested, especially for Pb and Zn. However, we come to the conclusion that, based on calculations of the required time to meaningfully reduce soil metals contents, phytoremediation is not a practical option for extremely metal-elevated soils. These findings should be verified under field conditions.
