Abstract—Using environmental scanning electron microscopy relative content of the different parts in oat grains, and
and X-ray electron probe microanalysis, Si, P, Mg, K, Ca, S, Cd, analyzed its distribution rule, the interrelationship of different
Al and Pb content was studied in the cortex, aleuronic layer, near parts as well as the relationship between Si content and Al, Cd,

genotypes of oat grains changed as cortex>aleuronic layer>near
