This project was design to test the impact of putrescine and salt on different biochemical attributes [photosynthetic pigments (chlorophyll b, chlorophyll a and carotenoids), reducing and non-reducing sugars, carbohydrates, total flavonoids, total proteins, total antioxidants and total phenols] of Zea mays L (corn). Experiment was arranged in a complete randomized design with different concentration of salt (40mM, 80mM,) and putrescine with different concentrations (0.5mM, 1mM and 2mM) was applied as a foliar spray. Reducing and non-reducing sugars, total proteins, different photosynthetic pigments and total carbohydrates showed significant decrease due to salinity while total antioxidant, phenols, and flavonoids increased with increased salinity. After the application of putrescine above mentioned parameters exhibited significant improvement under non-saline as well as saline condition. Foliar application of putrescine overcomes the harmful impacts of salt stress in Zea mays L.
