The use of ornamental plants for the phytoremediation of potentially toxic elements in polluted soils is an interesting task. It makes possible to combine environmental restoration, re-use of land, and the production of goods and services of economic interest. In this work, in vitro experiments using three cultivars of Chrysanthemum (Asteraceae) were carried out with 0, 300, 600, 900, and 1500 mg/kg of lead concentrations for a period of 12 weeks. The objective was to obtain data about their lead tolerance and bioaccumulation capacity in order to know their potential as phytoremediators in a densely populated Caribbean area of the Dominican Republic with a high concentration of lead in soils. The variations in biomass, root growth as well as accumulation of this element in the plants were measured. The results suggest that the three cultivars have a good potential for phytoextraction at moderate pollution levels, as they showed a good bioaccumulation of lead, which had mild effects on their biomass production and root elongation. Additional studies should be carried out to assess their effectiveness as phytoextractors under field conditions, as well as other alternative uses that could generate esthetic, environmental, and/or economic benefits for tropical areas contaminated by Pb.

使用观赏植物对污染土壤中潜在有毒元素进行植物修复是一项有趣的任务。它使环境恢复，土地再利用以及具有经济意义的商品和服务的生产结合起来成为可能。在这项工作中，使用了三个菊花品种的体外实验（菊科）用铅浓度分别为0、300、600、900和1500 mg / kg进行12周。目的是获得有关其铅耐受性和生物蓄积能力的数据，以了解其在多米尼加共和国人口稠密的加勒比地区土壤中铅含量高的植物修复剂的潜力。测量了植物中生物量，根的生长以及该元素的积累的变化。结果表明，这三个品种在中等污染水平下均具有良好的植物提取潜力，因为它们表现出良好的铅生物富集能力，对它们的生物量生产和根系伸长影响较小。在野外条件下，应进行其他研究以评估其作为植物提取物的有效性，
