Nanotechnology: A promising field in enhancing abiotic stress tolerance in plants

Abstract

Heavy metals, drought, salinity, cold stress, and heat stress are some of the main abiotic stresses that adversely affect plant growth and crop productivity generally. For crop production systems to be sustainable in the face of abiotic environmental constraints, effective strategies must be used in conjunction with technological advancement to achieve this goal. In recent times, the emergence of nanotechnology as an intriguing field of study with application potential in the field of agriculture needs to be given the necessary attention to address some of the abiotic stresses. Due to their environmental friendliness, affordability, special physicochemical properties, and increased plant productivity, the use of nanoparticles (NPs) as nano fertilizers has enormous potential and much interest has developed in the field in recent times. Abiotic stress management involves NPs, according to several studies. In order to create a practical and environmentally responsible plan for the long-term sustainability of agriculture, this review focuses on the effects of abiotic stress on plants, synthesis, and the roles of NPs in managing abiotic stresses, and future prospects.
