Mitigating Cd stress in alfalfa: the role of melatonin and nano-calcium oxide in enhancing photosynthesis and antioxidant defense

Abstract Background Heavy metal contamination, particularly cadmium (Cd), is a significant threat to agricultural productivity and food security. Melatonin, as a key biostimulant, plant growth regulator and stress resistance hormone, along with nano-calcium oxide (nCaO), can enhance plant resilience...
