(After Slrasburger.) gluten occur in this part of the endosperm. The percentage of gluten increases from the center outward; those cells next to the aleurone layer contain the largest amount. Embryo.—A median lengthwise section of the grain of wheat shows well the structure of the embryo (Fig. 36). The seminal roots point toward the micropylar end. They consist of a primary rootlet with two pairs of laterals. According to Brenchley, a fifth lateral rootlet is foimed in addition to the two pairs usually described. These rootlets are surrounded by the root sheath or coleorhiza. A very short.
