Silver nanoparticles (AgNPs) have demonstrated their remarkable ability to significantly influence crucial processes in plants. These processes include but are not limited to seed germination, the photosynthetic apparatus, antioxidant system activity, and the expression of genes vital for plant function, operating under both optimal and adverse conditions. The variability in the effects of AgNPs on plant growth and development across different plant species highlights the importance of gaining a nuanced understanding of these interactions. Current research underscores that various factors, including dosage, size, shape, surface charge, and capping agent, exert a substantial impact on the uptake, translocation, distribution, and growth enhancement effects of AgNPs in plants. This chapter thoroughly explores the intricate interactions between silver nanoparticles and plants, shedding light on the underlying mechanisms that contribute to the observed diverse outcomes. Furthermore, the discussion extends to the profound influence of AgNPs on plant growth and development, underscoring their potential to enhance nutrient uptake and facilitate targeted delivery. This contribution ultimately plays a pivotal role in increasing plant productivity and yield. Additionally, the comprehensive investigation into the impact of silver nanoparticles on plant defense mechanisms against pathogens and pests reveals their promising antimicrobial and antifungal properties. This presents AgNPs as a potential eco-friendly alternative to traditional pesticides. The multifaceted nature of these interactions emphasizes the transformative potential of silver nanoparticles in revolutionizing agricultural practices. Their ability to contribute to sustainable and environmentally friendly crop management further solidifies their position as agents of positive change in the realm of agriculture.
