Chromium (Cr) toxicity can negatively affect plant growth and development, impacting agricultural productivity and posing risks to human health. Metallic nanoparticles (MNPs) such as titanium dioxide (TiO 2 ) and natural growth regulators such as melatonin (MT) become promising technology to manage heavy metal-contaminated soils and promote safe food production. The present work was conducted to nd the effect of foliar application of TiO 2 NPs (15 Mg L − 1 ) and MT (100 µM) on growth, biochemical attributes, and Cr accumulation in plant tissues of melissa o cinalis L. under Cr toxicity (50 and 100 mg Cr kg − 1 soil). The results showed that Cr toxicity led to decreased plant performance, where 100 mg Cr kg − 1 soil led to notable decreases in shoot weight (28%), root weight (27%), essential oil (EO) yield (34%), chlorophyll (Chl) a + b (33%), while increased malondialdehyde (MDA, 30%), superoxide dismutase (SOD) activity (51%), and catalase (CAT) activity (122%). The use of TiO 2 NPs and MT, particularly their coapplication, remarkably reduced Cr toxicity by enhancing plant weight, Chl content, and lowered MDA and antioxidant activity. Total phenolic content (TPC), total avonoid content(TFC), EO percentage, and rosmarinic acid in plants treated with Cr at 50 mg Cr kg − 1 soil and co-application of TiO 2 NPs and MT were relatively higher than in other treatments. Under 100 mg Cr kg − 1 soil, the synergic effect of TiO 2 NPs and MT enhanced rosmarinic acid content (22%) but lowered Cr accumulation in roots (51%) and shoots (72%). Heat map analysis showed that ACT, SOD, MDA, and EO yield had the maximum variability under Cr, TiO 2 NPs, and MT. Exogenous TiO 2 NPs and MT can be recommended to modulate Cr toxicity in lemon balm under soil Cr toxicity.
