Chromium (Cr) contamination in soil is a growing concern in sustainable agricultural production and food safety. Remediation of Cr from contaminated soils is a challenging task which may not only help in sustaining agriculture but also in minimizing adverse environmental impacts. Pot culture experiments were performed with the application of varied concentration of Cr⁺⁶ to assess the Chromium accumulation potential of Lemongrass and to study the impact of toxic concentration of Cr⁺⁶ on morphological, physiological and biochemical parameters of the plant. The results showed an increasing accumulation trend of Chromium with increasing Chromium concentrations in both root and shoot of 60 days old Lemongrass plants, while the protein and chlorophyll contents decreased. Similarly, accumulation of Cr increased the levels of proline and antioxidant enzymes indicating the enhanced damage control activity. The potentiality of the plant with the capacity to accumulate and stabilize Cr compound in Cr contaminated soil by phytoremediation process has been explored in the present investigation.

土壤中的铬（Cr）污染已成为可持续农业生产和食品安全中日益受到关注的问题。从受污染的土壤中修复铬是一项艰巨的任务，不仅有助于农业持续发展，而且还可以最大程度地减少对环境的不利影响。使用不同浓度的Cr ⁺⁶进行盆栽实验，以评估柠檬草的铬积累潜力，并研究有毒浓度的Cr ⁺⁶的影响。对植物的形态，生理和生化参数的影响。结果表明，60天龄柠檬草植株根部和茎部中铬的累积趋势均随铬浓度的增加而增加，而蛋白质和叶绿素含量却下降。同样，Cr的积累增加了脯氨酸和抗氧化酶的水平，表明增强了伤害控制活性。在本研究中，已经探究了具有通过植物修复过程在Cr污染土壤中积累和稳定Cr化合物的能力。
