The effects of silver nanoparticles on seed germination and seedling growth / Wan Nor Adlina Abdul Aziz

Silver nanoparticles have various applications in various fields. Silver nanoparticles positive role in the environment, especially in plant ecosystem, is extensively studied nowadays. Among the metal nanoparticles, the silver nanoparticles (AgNP) are receiving special attention because of their ability to increase the growth and yield in many crops. During this overview, there are many methods of synthesizing silver nanoparticles discussed, including chemical, bacterial-induced, fungal-derived and plant-mediated synthesis. Silver nanoparticles possess unique properties which find myriad applications such as antimicrobial and anticancer activities. It was concluded that cautious and sensible use of nanotechnology can warrant food security through boosting agricultural production. Although many studies are found containing toxic effects of AgNPs the perspective of the present review is to collect the information about their positive role in growth and yield enhancement of crops. This review is aimed at providing an insight into the syntheses of silver nanoparticles, its significant applications in various fields, and characterization techniques involved.
