Buckwheat, Avena sativa, the difference between oats: different forms, different distribution, different nutritional value.

1, different forms

Buckwheat: annual herbs. Stem erect, 30 ~ 90 cm high, upper branches, green or red, with longitudinal ribs, glabrous or on one side along the longitudinal ribs with papillae.

Leaves triangular or ovate-triangular, 2.5-7 centimeters long, 2-5 centimeters wide, apically acuminate, base cordate, papillate along the nerves on both surfaces; lower leaves long-petiolate, upper smaller and nearly sessile; ocrea membranous, short cylindrical, ca. 5 millimeters long, apically oblique, ciliate-free, easy to rupture and fall off.

Oat: annual herb. The outside of the fibrous roots often with a sandy covering. Culms erect, tufted, 60-100 cm tall, usually with 2-4 nodes. Leaf sheaths loose, basal ones longer than internodes, often hirsute, sheath margins hyaline-membranous; ligules hyaline-membranous, ca. 3 mm, apices obtuse-rounded or slightly toothed; leaf blades flattened, soft, 8-40 cm long, 3-16 mm wide, slightly scabrous.

Oats: spikelets containing 1~2 florets; rachilla subglabrous or sparsely short hairy, not readily broken off; first lemma dorsally glabrous, basal disc with only a few short hairs or subglabrous, awnless, or with only 1 straight awn on dorsal side, second lemma glabrous, usually awnless.

2, different distribution range

Buckwheat: In general, buckwheat in China is mainly distributed in Inner Mongolia, Shaanxi, Gansu, Ningxia, Shanxi, Yunnan, Sichuan, Guizhou, followed by Tibet, Qinghai, Jilin, Liaoning, Hebei, Beijing, Chongqing, Hunan, Hubei and other regions.

Avena sativa: It is cultivated in the provinces and regions of northwest, southwest, north China, and Hubei, and is also found wild on mountain slopes, in alpine meadows, and in damp places.

Oats: mainly distributed in the northern hemisphere temperate regions. Provinces and regions where oats are grown are mainly Hebei, Mongolia and Shanxi, followed by Gansu, Ningxia, Shaanxi, Qinghai and the mountainous regions of Sichuan, Yunnan and Guizhou.

3, different nutritional value

Buckwheat is not only nutritionally comprehensive, but also rich in bioflavonoids, multi-skin, sugar alcohols and D-chiral inositol and other highly active medicinal ingredients, with hypoglycemic, hypolipidemic, cholesterol-lowering, antioxidant, anti-aging, and scavenging free radicals.

Avena sativa is recognized as one of the world's high nutritional value of grain species, its nutritional value of cereal grain. Avena sativa has the highest protein content in cereal grains. It contains a complete range of amino acids, the body's eight essential amino acids are not only high, and balanced. Avena sativa lysine content is rice, wheat flour, cornmeal, sorghum rice, millet more than two times.

Oats rich in vitamins, minerals and amino acids, etc., for the enhancement of health, promote development, participate in the metabolism, against disease, etc., have an extremely important role.
