| Abstract: | This paper studied the content distribution and species of selenium in the accumulating selenium corn grain. The results indicated that the selenium content achieved above 90% from the organic matter in the corn, the main species of selenium were combined with polysaccharide and protein, and selenium in protein occupied the total selenium 61.51%. The contents of salt dissolved protein and alkali dissolved protein combining selenium of the selenium in protein were higher, separately occupying the total selenium 19.83% and 25.64%. |
