Abstract: The different concentration of se soulution was used for wheats to optimum enrich selenuim, the value of wheats tolerance to selenium was be determination, the main nutritional components and antioxidant activity of Se-enriched wheat were be determinated.The results were as follows:selenium-rich wheat could tolerant a maximum selenium concentration of 80μg/mL.The optimum germination condition was soak for 6h with a selenium dose of 40μg/mL, sprayed at 10h of germination, its germination temperature was 20℃ and germination time was 2d.Subsequent work suggested that germination of selenium-enriched effectively improve the selenium content of wheat especially organic selenium content, and the protein concent of wheat.Starch content was not significantly affected.The result of antioxidant analysis showed that selenium could effectively improve the antioxidant ability of wheat.
