The genus is recognized for including species with phytoaccumulation potential and a large amount of research has been carried out in this area under a variety of conditions, from laboratory experiments to field trials, with spiked or naturally contaminated soils, using one- or multi-element contaminated soil, generating various and sometimes contradictory results with limited practical applications. To date, the actual field potential of species and the feasibility of a complete phytoextraction process have not been fully evaluated. Therefore, the aim of this study was to summarize the results of the experiments that have been performed with a view to analyzing real potentials and limitations. The reduced biomass and low metal mobility in the soil have been addressed by the development of chemically or biologically assisted phytoremediation technologies, the use of soil amendments, and the application of crop management strategies. Certain issues, such as the fate of harvested biomass or the performance of species in multi-metal-contaminated soils, remain to be solved by future research. Potential improvements to current experimental settings include testing species grown to full maturity, using a greater amount of soil in experiments, conducting more trials under real field conditions, developing improved crop management systems, and optimizing solutions for harvested biomass disposal.
该属因包含具有植物积累潜力的物种而被认可，并且在这一领域已经在各种条件下开展了大量研究，从实验室实验到田间试验，使用添加了污染物或天然受污染的土壤，采用单元素或多元素污染土壤，得出了各种各样、有时相互矛盾的结果，实际应用有限。迄今为止，该属物种的实际田间潜力以及完整植物提取过程的可行性尚未得到充分评估。因此，本研究的目的是总结已进行的实验结果，以便分析实际潜力和局限性。通过开发化学或生物辅助植物修复技术、使用土壤改良剂以及应用作物管理策略，解决了土壤中生物量减少和金属迁移率低的问题。某些问题，如收获生物量的去向或物种在多金属污染土壤中的表现，仍有待未来研究解决。当前实验设置的潜在改进包括测试生长至完全成熟的物种、在实验中使用更多土壤、在实际田间条件下进行更多试验、开发改进的作物管理系统以及优化收获生物量处置的解决方案。
