The potential effects of quantum dots (QDs) on plant growth and development have recently attracted attention, opening up a new line of inquiry for plant science research. This review offers a thorough summary of how QDs affect different facets of plant physiology, with an emphasis on how they affect growth, metabolism, and stress reactions. According to recent research, QDs can control plant growth processes like biomass accumulation, root elongation, and seed germination because of their special optical and physicochemical characteristics. Furthermore, QDs have been linked to improved nutrient uptake, antioxidant defense mechanisms, and photosynthetic efficiency in plants, all of which support general growth and stress tolerance. Still, there is a need to carefully consider the potential toxicity and environmental impact of QDs, as their effects on plant physiology are not fully understood. Additionally, although stability, biocompatibility, and regulatory approval present obstacles, the development of QD-based nanobiotechnologies holds promise for applications in plant imaging, sensing, and targeted delivery systems. Future research should focus on refining QD synthesis to enhance their safety and efficacy in agricultural settings, as well as on long-term studies to assess the environmental impacts of their widespread use. To sum up, the application of QDs in plant science presents stimulating prospects for deciphering the complex mechanisms that dictate plant growth and for formulating novel approaches for environmentally sound farming practices.
