Studies on the Nitrogen Metabolism of Rice Plant. (I) : The Protein Content and Quality of White Rice as Affected by Latest Nitrogen Application After Heading. (3)

Abstract

The proteins, especially oryzenine, in white rice are increased about 10% or more by nitrogen application at heading. The nitrogen content of the bran layer is also increased, but the layer's thickness is not affected. Further the increase of lysine and threonine contents in white rice are seemed to be possible.
