Melatonin (MT) and brassinolide (BL) are phytohormones that regulate various physiological processes in plants. This study investigates their effects on Wolffia arrhiza when exposed to cadmium (Cd). Plant hormones were quantified using liquid chromatography-mass spectrometry, while photosynthetic pigments phytochelatins (PCs) analyzed through high-performance chromatography. Protein, monosaccharide levels, antioxidant activities also spectrophotometrically measured. The findings reveal MT BL treatment decreased Cd accumulation W. compared plants only Cd. was particularly effective reversing Cd-induced growth inhibition reducing stress markers more significantly than BL. It enhanced activity maintained higher levels of pigments, proteins, sugars. Although less these aspects, it promoted greater synthesis glutathione PCs Cd-exposed duckweed. Overall, both alleviate the negative impact arrhiza, confirming crucial role supporting plant health under metal conditions.
