The difference between oats and wheat is mainly reflected in the plants, flowers and fruits. In terms of plants, the stems of wheat are upright, the leaf sheaths wrap around the stems, and the leaves are long lanceolate; the stems of oats are upright and smooth, and the leaves are flat. In terms of flowers, wheat has upright spikes with three to nine florets in the spikelets; oat flowers have conical inflorescences with two or several florets in the spikelets. In terms of fruit, wheat caryopses are yellow-brown and oblate; oat caryopses are wide and grassy in texture.

Basic introduction to wheat: It is the collective name for plants of the genus Triticum. It has a long history of cultivation and is widely distributed. Its caryopsis is one of the staple foods of humans. After being ground into flour, it can be made into bread, steamed buns and other foods, as well as beer, liquor, etc. It is one of the three major cereals, and almost the entire plant can be eaten.

Oats: It is an ancient crop and one of the eight major cereal crops. It belongs to the family Poaceae, the oat family, and the genus Oat. It is an important grain that is widely grown all over the world. It can also be used as a feed crop. It has strong drought resistance, cold resistance, and can tolerate barrenness. It also has high nutritional value and has certain medical effects.

The difference between the two plants: the stems of wheat are upright and clustered, with a height of sixty to one hundred centimeters and a diameter of five to seven millimeters. The sheath of its leaves loosely wraps the stem, the ligule is membranous, about one millimeter in length, and the leaves are long lanceolate. The stems of oats are upright and smooth, and the sheaths of the leaves are also very smooth. There are micro hairs on the back, the ligule is relatively large, there are no ears, and the leaves are flat.

The inflorescences of wheat are upright and spike-shaped, with a length of about five to ten centimeters and a width of about one to one and a half centimeters. The spikelets contain three to nine flowers. The flowers of oats are in the form of cone-shaped inflorescences, the cob is pendulous or upright, the inflorescence is terminal, and the spikelet contains two or several small flowers.

The fruit of wheat is a caryopsis, with a yellow-brown peel and an oblate or oval shape. The ends of the fruit are somewhat pointed or blunt, and there are starch granules inside. The powder of the fruit is white, mixed with small pieces of yellow-brown peel. The caryopses of oats are wide and grassy in texture, and the lemma is hard and hairless, some with awns and some without awns. The abdomen of its caryopse has a longitudinal groove and is covered with sparse hairs. When it matures, the inner and outer lemmas tightly wrap the kernels, making it difficult for them to separate.
