Determining the Structure of the Barley Kernel by Scanning Electron Microscopy.

Y. Pomeranz and I. B. Sachs. Copyright 1972 by the American Association of Cereal Chemists, Inc. 

The barley kernel consists of the husks (that include the lemma and the palea), the caryopsis, and the rachilla. The caryopsis is composed of the pericarp, seed coat, endosperm, and germ. The detailed structure of husks and awns, ridges and stomata-like cells on the husks, the rachilla, the pericarp, and the endosperm are illustrated by scanning electron microscopy. Detailed pictures and description of aleurone cells and their contents, subaleurone layer, and starchy endosperm and its contents in barley are given.
