One of the most harmful trace elements is cadmium (Cd) because of its persistence and high mobility. As Cdcontamination of soils increases worldwide, techniques to reduce the lettuce plant's Cd accumulation are required. The adverse effects of Cd can be reduced or eliminated using indigenous garlic peel (IGP) and, to a greater extent, mercerized garlic peel (MGP). In addition, the adsorption capacity of garlic peel after mercerization increased compared to indigenous garlic peel. This investigation explored the efficacy of IGP or MGP on the growth characteristics, Cd concentration, and biochemical processes in Cd-stress lettuce plants using a hydroponic growing system. The results demonstrated that IGP or MGP mitigated Cd's toxicity, improving lettuce growth, reducing Cd content, translocation factor, biological accumulation factor, tolerance index, malondialdehyde, and oxidative stress in both leaves and roots. In addition, the application of IGP and MGP significantly increased the non-enzymatic and enzymatic antioxidants in leaves and roots under Cd stress. Furthermore, all treated plants displayed high expression levels of certain regulatory defense genes, UBC21, LOX, and PAL.
