摘要 The global understanding of selenium(Se)in plant biology mainly comes from the fields of medicine and animal science,while the research on Se in plant biology in the field of plant science lags behind.This paper summarized the physiological functions of Se in plants.These studies indicate that Se can promote plant seed development and growth and plant photosynthesis,increase plant economic yield and quality,and enhance plant antioxidant capacity and resistance to stress.However,its effects have a"dual"character,and its concentration or dosage range is very narrow.At appropriate concentrations,Se has an important impact on the physiological processes of plants and is a beneficial element for many plants to maintain health and good growth and development.
