The difference between grain buds and rice buds is that the ontology is different, the appearance is different, and the distribution area is different.

I, the ontology is different

1, grain buds: grain buds for the graminaceous plant corn's ripe fruit by germination and drying of the concoction of processed products.

2, rice buds: rice buds for the mature fruit of the graminaceous plant rice by germination and drying of the concoction of processed products.

Second, the appearance of different

1, grain buds: grain buds are spherical, about 2mm in diameter, bluntly rounded at the tip, the base is slightly pointed. The outer shell is a leathery lemma, pale yellow, with punctate wrinkles, with incipient fine fibrous roots at the lower end, about 3-6mm long, peeling off the lemma, containing pale yellow or yellowish-white caryopsis (millet) grains.

2, rice shoots: the shoots are oblong-elliptic, slightly pointed at both ends, 7-9mm long, about 3mm in diameter, with yellow lemmas, white velutinous, and 5-veined. The lemma is yellow, with white fine velvet, with 5 veins. There are 2 symmetrical white bar-shaped plasma sheets at one end, 2-3mm long, and 1-3 curved fibrous roots extending from the inner side of one plasma sheet, 0.5-1.2cm long.

Three, different distribution areas

1, grain buds: grain buds are cultivated in the north and south regions of China.

2, rice buds: rice buds are widely cultivated in the southern and central regions of China.
