Glutathione (GSH) abundantly presents in plant and affects plants growth and development. To justify if GSH affects copper (Cu) induced corn production, photosynthesis (Pn) rate, and photosynthetically active radiation (PAR), chlorophyll (Chl) content and Chl fluorescence, relative water content (RWC) and yields were evaluated. Different Cu concentrations (0, 0.2, 1.5 and 3.0 ppm of Zn) with or without 100 μm of Nacetyl cysteine (NAC) were arranged as completely randomize design with 5 replications. Results showed that both NAC and Cu affected plant height and leaf numbers. Copper reduced Pn rate, and PAR and increased RWC but no effect was observed on Chl content and Chl fluorescence in leaves. On the other hand, NAC application increased Pn, PAR, Chl parameters regardless of Cu treatment. In the presence of 1.5 ppm of Cu, corn plants showed improve yield and cob length irrespective to NAC treatment. Taken together, this study suggests that NAC might improve some physiological functions in plants to enhance Cuinduced corn production.
