Barley is a genus of the Tritici family in the subfamily Bluegrass

Wheat is a genus in the Tritici family of the subfamily Bluegrass

Oats are a species in the subfamily Brassicae family Oats Genus

(1) Wheat Morphological Characteristics

Wheat morphological characteristics, wheat belongs to the Poaceae family, with ***5 species. Wheat grain production is called seeds, which are indehiscent. Caryopses containing single seeds, the seeds are red or white in color.

When the wheat fruit matures, the seed coat and pericarp of the single seed are closely connected and difficult to separate.

Grain-shaped and oval, one side is flat, the back is smooth, and the side facing the lemma has an indented ventral groove.

There are short and tough fruit hairs on the top of the seeds. The embryo is implanted at the base of the back of the fruit and is about 1/4-/1/3 of the length of the seed. It is located on the opposite side of the ventral groove and is covered by the obviously shrunken seed skin. The two sides of the abdominal groove are called fruit cheeks, which are generally round and raised.

(2) Barley morphological characteristics and subspecies identification

Barley belongs to the genus Hordeum of the family Poaceae, which has nearly 30 species

Barley includes hulled barley (hulled barley) and naked barley. Barley usually refers to hulled barley.

The grain skin of most varieties of barley can secrete a sticky substance when mature, which tightly combines the inner and outer lemmas, so that it cannot be separated from the grain after maturity, so it is often called hulled barley, while the grains of a few varieties The skin does not secrete sticky substances, and the kernels are separated from the inner and outer lemmas, so it is called naked barley.

(3) Morphological characteristics of oats;

Oats are also called oats, oil wheat, corn wheat, etc., and belong to the genus Oat in the family Poaceae. There are 16 species of Oats.

The most widely cultivated in my country are hulled oats (Avena Sativa L.) and naked oats (a. nuca L.) among common oats.

The former has long and hard galls, while the latter has short and soft galls. Generally speaking, oats are naked oats, and their protein content can be as high as 21%. Oat kernels, except naked oats, are firm inside and outside, but shelling is easier than hulled barley.

The grains are oblong and have hairs on the surface. Their internal structure is roughly the same as that of wheat. There are two layers of cells in the aleurone layer, while wheat has only one layer.
