2. The difference between the two

Plant difference: the stem of wheat is upright and tufted, with a height of 60 to 100 cm and a diameter of 5 to 7 mm. The sheath of its leaves loosely wraps the stem, the tongue is membranous, the length is about 1 mm, and the leaves are long lanceolate. The stem of oat is upright and smooth, the sheath of leaves is also very smooth, there are micro hairs on the back, the tongue is relatively large, there is no auricle, and the leaves are flat

Flower difference: the inflorescence of wheat is spike like and erect, with a length of about 5 to 10 cm and a width of about 1 to 1.5 cm. The spikelet contains three to nine flowers. The flowers of oats are paniculate inflorescences, the rachis is pendulous or upright, the inflorescence is terminal, and the spikelets contain two or more florets

Fruit difference: the fruit of wheat is caryopsis, the pericarp is yellowish brown, and the shape is oblate or oval. There are some sharp or blunt circles at both ends of the fruit, with starch grains inside. The powder of the fruit is white, mixed with small pieces of yellowish brown peel. The caryopsis of oats is broad and herbaceous in texture. The lemma is hard and glabrous, some awned and some awnless. The abdomen of its caryopsis has longitudinal grooves and is covered with sparse hairs. The lemma is easily separated from the inner lemma when it is not mature
