Conclusion
Environment eco-friendly synthesized zinc oxide nanoparticles effect on the mung bean seed germination. It penetrates easily inside the plant cell wall and causes effects on biomass and growth parameters of mung bean plant. Deposition of small size nanoparticles inside the cell wall and vacuoles causes disturbance in metabolic activity of plant. Mungbean (Vigna radiata) are economically important crop plant, nanoparticles can easily find their way in human body through food chain. More investigations are needed to determine the positive and negative impact of nanoparticles on crop plant and its consequences in other living organisms.
