【Abstract】 Nitrate accumulation in vegetables has posed detrimental threats to food safety and human’s health. This review paper was concerned on differences of nitrate accumulation in plant spiecies and cultivars, as well as in different plant organs; absorption and tranporta tion of nitrate by plants, and its nutritional and physiological functions; the role of nitrate reductase in nitrate reduction; and induction and regulation of nitrate reductase activity. In the conclusion, issues needed further research in the field of plant nitrate accumulation was posed out.更多还原
