Abstract: In this review paper，we summarize current knowledge about the absorption，transformation，and accumulation of selenium in plants. We also review the influence of exogenous selenium application on the yield，quality，and total selenium content of vegetables. The effect of exogenous selenium on organic selenium transformations in vegetables is also reported. Existing research indicates that the application of exogenous selenium can increase not only the transformation of organic selenium to inorganic selenium in vegetables but also the total selenium content of vegetables. The exact effect depends on the species and growth stage at the time of selenium application. Future research about selenium-rich vegetables should focus on the standardization of selenium application methods.
