I. Plant Differences

Wheat has erect, tufted stalks with 6 to 7 nodes, 60 to 100 centimeters tall, 5 to 7 millimeters in diameter, leaf sheaths loosely wrapped around the stalks, ligules membranous and about 1 millimeter long, and long lanceolate leaf blades.

The stem of oats is erect and smooth, the leaf sheaths are smooth and slightly hairy on the back, the ligule is large and without auricles, and the leaf blades are flattened.

The difference in flowers

Wheat has an erect spike, about 5 to 10 centimeters long and 1 to 1.5 centimeters wide, with 3 to 9 flowers in the spikelet.

Oats has a panicle of flowers with an erect or pendulous rachis, the inflorescence is terminal, and the spikelets contain two or more flowers.

Three, fruit difference

Wheat fruit is caryopsis, pericarp yellow-brown, oblate or ellipsoid, the ends of the fruit is slightly sharp or obtuse rounded, there are starch grains, the powder of the fruit is white, with yellow-brown pericarp flakes.

The glumes of oats are broad, herbaceous, the lemmas hard and glabrous, some with awnless awns; the ventral surfaces of the glumes are longitudinally furrowed, and sparsely tomentose; at maturity, the palea and lemma are tightly clasped around the kernel, and are not readily separated.
