Nitrogen is an important component of plant nucleic acids, proteins and chlorophyll. It is an essential nutrient element required for the plant growth and development. It is also one of the important factors limiting the growth of plants. This review introduces several important aspects of nitrogen metabolism including arginine metabolism, urea metabolism pathway and glutamine synthetase assimilation process, and also induces and summarizes the response mechanisms of nitrogen metabolism on the seed germination and seedling growth. In addition, it also importantly summarizes the research advances in the effects of the nitrogen metabolism on seed germination and seedling growth of plants. At the same time, this review briefly summarizes the application values of nitrogen in crop production, environmental pollution and ecological conditions and so on, and also discusses the limitations and deficiencies of nitrogen metabolism research, providing the certain theoretical foundations for the research of the effects of nitrogen metabolism pathway on the seed germination and seedling growth of plants.
