Chromium (Cr) is considered one of the most hazardous metal contaminant reducing crop production and putting human health at risk. Phytohormones are known to regulate chromium stress, however, the function of melatonin and strigolactones in Chromium stress tolerance in tomato is rarely investigated. Here we investigated the potential role of melatonin (ML) and strigolactone (SL) on mitigating Chromium toxicity in tomato.

Application of GA and Si enhanced the antioxidant enzyme activities of (APX, CAT, GR, SOD) in seedlings under NaCl toxicity. The exogenous Si application decreased Na uptake and enhanced the K and Ca in salt stressed .

The metal concentration was much higher in FA compared to the garden soil/(control).

FA stress caused significant changes in different leaf attributes like sugar, protein contents, photosynthetic pigments, nitrate content and nitrate reductase activity in foliar tissues of plants growing at a highly contaminated site, as compared to a low-pollution site.
