Phytoremediation is an ecologically and economically feasible technique to remove heavy metal from soil. The aim of the study was to examine cadmium (Cd) toxicity and phytoremediation aptitude of Brassica juncea. In the present study, plants survived when exposed to different levels of Cd (0, 25, 50 and 100 mg/kg soil) and accumulated a large amount of Cd in its root and shoot. Translocation factor (TF) of Cd from root to shoot was > 1 at both 45 and 60‐day stage of growth suggesting that B. juncea is a hyperaccumulator and strong candidate for phytoextraction of Cd. Alongside, Cd impaired photolysis of water, PSII activity, nutrient uptake, photosynthesis and sugar accumulation in the plant. Cd-generated oxidative stress restricts the growth of B. juncea. The toxic effect of Cd was more pronounced at 45‐day stage of growth signifying the drifting of plant towards acquirement of exclusion strategy.

植物修复是一种从土壤中去除重金属的生态和经济可行技术。这项研究的目的是检查芥菜对镉（Cd）的毒性和植物修复能力。在本研究中，当暴露于不同水平的Cd（0、25、50和100 mg / kg土壤）时，植物得以存活，并且在其根和茎中积累了大量Cd。在生长的第45天和第60天，从根到芽的Cd转运因子（TF）均大于1，这表明芥菜芽孢杆菌是Cd植物超富集和强力提取的候选者。同时，镉会损害植物的水分，PSII活性，养分吸收，光合作用和糖分的光解。镉产生的氧化应激限制了芥菜的生长。在生长的第45天，镉的毒性作用更加明显，表明植物向获得排斥策略的漂移。
