In recent years, there has been a growing focus on utilizing suitable plant species for the extraction of heavy metals from contaminated soils. Trees offer a more economically viable option for remediating heavy metal-contaminated soils as their extensive root systems, substantial biomass, lower requirements, and management contribute to reduced operational costs. This study seeks to enhance the understanding of metal accumulation in (L.) H.Karst. and to investigate the variation among different genotypes from the Markazi province in Iran. The genotypes were selected from 11 distinct locations within central Markazi province. One-year-old cuttings were planted in contaminated soil from the effluent outlet of an industrial area in mid-April. The morpho-physiological characteristics and levels of heavy metals in the plant tissues were assessed after a duration of three months.
The results revealed that the roots of the Ahmad-Abad genotype exhibited the highest levels of copper, iron, manganese, and zinc absorption, whereas its branches demonstrated the greatest sodium uptake. Notably, the Ahmad-Abad genotype also showed the highest potassium absorption. Collectively, these findings suggest that the Ahmad-Abad genotype is particularly suitable for phytoremediation efforts in contaminated environments due to its capacity to accumulate elevated levels of heavy metals.
The research study provides valuable insights into genetic variation, ecotype diversity, and the potential for genetic engineering to enhance phytoremediation processes in .
近年来，人们越来越关注利用合适的植物物种从污染土壤中提取重金属。树木为修复重金属污染土壤提供了一种更具经济可行性的选择，因为它们广泛的根系、大量的生物量、较低的要求以及管理有助于降低运营成本。本研究旨在增进对（L.）H.Karst.中金属积累的理解，并调查伊朗马尔卡齐省不同基因型之间的差异。这些基因型是从马尔卡齐省中部11个不同地点选取的。一年生插条于4月中旬种植在一个工业区废水排放口的污染土壤中。三个月后评估植物组织中的形态生理特征和重金属含量。
结果表明，艾哈迈德 - 阿巴德基因型的根系对铜、铁、锰和锌的吸收水平最高，而其枝条对钠的吸收量最大。值得注意的是，艾哈迈德 - 阿巴德基因型的钾吸收量也最高。总体而言，这些发现表明，艾哈迈德 - 阿巴德基因型因其积累高水平重金属的能力，特别适合在污染环境中进行植物修复工作。
该研究为（植物名称未完整给出）中的遗传变异、生态型多样性以及通过基因工程增强植物修复过程的潜力提供了有价值的见解。
