us plants is generally similar. Maturelegume seeds have three major components: the seed coat, the cotyledons, and the embryoaxis, which

constitute 8, 9, and 2% of the seed, respectively. The structure of typicallegume seeds and their various anatomical parts of

the seed are shown in Figs. 8 and 9.The outer layer of the seed is the testa or seed coat.

In most legumes, the endosperm is short-lived and, at maturity, it is reduced to thin layer surrounding the cotyledons or

embryo. The external structure of the seed includes helium, micropyle, and raphe. Aftersoaking and removing the seed coat of bean, the endosperm comes off, and the reminderis composed of embryonic structure. The embryonic structure includes the shoot, whichconsists of two cotyledons, and short axis above and below the cotyledons, which has Fig. 8 Cross sections of mature broad seed with one cotyledon removed. (From Kadam et al., 1.) Structure and Composition of Cereal Grains 1 Fig. 9 Mung bean seed coat and cotyledon. (From Kadam et al., 1.) several foliage leaves, and terminates in the short tip. The embryonic stem and plumule are fairly well developed in the resting seed and lie between two cotyledons or seed leaves.The radicle or embryonic root has almost no protection except that provided by the seedcoat. Therefore, the seed is unusually breakable, especially when it is dried and roughlytreated. Usually, legumes have moderately thick seed coat. Legume seeds having thick seed coats have higher amounts of lipids. The outermost layer of the seed coat is usually known as the cuticle . The other two important features in the external topography of the seed include the hilum andmicropyle . The hilum of the legume is different from others in shape and size, ranging from round to oblong, oval, or elliptical. The micropyle shows variation, ranging from circular and triangular to fork-shaped. The cotyledons of legumes seeds are composed of numerous oarenchymatous cells. The size of the parenchymatous
