The aim of this study was to gain a better understanding of how adapts to growth in soil with higher concentrations of heavy metals and to assess potential toxic effects using various biomarkers, in comparison to , a typical serpentine species. For this purpose, we analyzed the concentrations of Al, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, and Zn in the soil, as well as their accumulation in plants and their associated stress effects. The results indicate that, despite the presence of some metals in very high concentrations in the soil (Al, Fe, Mn, and Ni), they are translocated in minimal amounts within plant organs, particularly in . Nearly all metals exhibited significantly higher concentrations in when compared to . Based on the analysis of biomarkers, it is apparent that shows greater sensitivity to these conditions. This is evident through the decreased activity of δ-aminolevulinic acid dehydratase and levels of δ-aminolevulinic acid, malondialdehyde, and glutathione observed in . It appears that effectively restricts the absorption of metals in serpentine soils; however, it experiences oxidative stress induced by these metals, setting it apart from the more resilient .
本研究旨在更好地了解在土壤中重金属浓度较高的情况下如何适应生长，并使用各种生物标志物评估潜在的毒性影响，与典型的蛇纹石物种相比。为此，我们分析了土壤中 Al、Ca、Cd、Co、Cr、Cu、Fe、Mg、Mn、Ni、Pb 和 Zn 的浓度，以及它们在植物中的积累及其相关的胁迫效应。结果表明，尽管土壤中存在一些浓度非常高的金属（Al、Fe、Mn 和 Ni），但它们在植物器官中的迁移量非常少，尤其是在中。几乎所有金属在中的浓度都明显高于。基于生物标志物的分析，表明对这些条件表现出更高的敏感性。这可以通过在中观察到 δ-氨基酮戊酸脱水酶和 δ-氨基酮戊酸的活性降低以及丙二醛和谷胱甘肽的水平来证明。似乎有效地限制了蛇纹石土壤中金属的吸收；然而，它经历了这些金属引起的氧化应激，使其与更具弹性的区别开来。
