Wheat belongs to the wheat family of Poa subfamily.
Oats belong to Poa subfamily.
(A) the morphological characteristics of wheat
Morphological characteristics of wheat, wheat belongs to Gramineae, with 5 species. In wheat grain production, it is called seed, which is the caryopsis of a single seed, and the color of the grain is red and white.
When the wheat fruit is ripe, the seed coat and pericarp of a single seed are closely connected and difficult to separate.
Grain-shaped oval, flat on one side, smooth on the back, with an invaginated abdominal groove on the side facing the lemma.
There are short and tough fruit hairs at the top of the grain. Embryo is attached to the back base of the fruit, and its length is about1/4-1/3 of the grain length. It is located on the opposite side of the abdominal sulcus and is covered by obviously shriveled seed skin. Both sides of the abdominal sulcus are called fruit cheeks, which are generally in a circular uplift state.
(2) Morphological characteristics and subspecies identification of barley.
Barley belongs to Gramineae, with nearly 30 species.
Barley includes hulled barley (hulled barley) and naked barley, and barley usually refers to hulled barley.
Most varieties of barley can secrete a sticky substance when they are ripe, so that the inner and outer lemmas are closely combined and cannot be separated from the seeds when they are ripe, so they are often called hulled barley. A few varieties of barley do not secrete sticky substances and the seeds are separated from the inner and outer lemmas, so they are called naked barley.
(3) Morphological characteristics of oats;
Oats, also known as naked oats, oil wheat, jade wheat and so on. , belonging to the genus Avena. There are 16 kinds of oats,
Oats and oats are the most widely planted common oats in China.
The former glume is long and hard, while the latter glume is short and soft. Naked oats are generally naked oats, and the protein content can be as high as 2 1%. Except naked oats, oat seeds are compact inside and outside, but hulling is easier than hulling of barley.
The seeds are oval with fluff on the surface, and the internal structure is roughly the same as that of wheat. Its aleurone layer has two layers of cells, while wheat has only one layer.
