Nanotechnology consists of large surface area particles at atomic level ranging from 1-100 nm in diameter. Given such properties, this technology is widely used in various fields of agriculture due to its easy penetration and mobility in plant cells. One of the main functions of nanoparticles is antimicrobial action which makes them an effective preservative solution to enhance the vase life of cut flowers. Apart from inhibiting growth of microorganisms, particularly, bacteria by increasing membrane permeability in vase solution, they also prevent ethylene biosynthesis and increase the activity of antioxidant enzymes. This review discusses different nanoparticles (including carbon nanotubes, silicon, copper, and zinc), their function, synthesis method, concentration and their effect on enhancing postharvest life of cut flowers.
