Description

It has a well-developed root system, mainly distributed in the soil layer of 5-30 cm. It is an annual herb. The underground part has round, oval or spindle-shaped roots. The shape, skin color and flesh color of the roots vary depending on the variety or soil. The stem lies prone or ascending, occasionally entwined, multi-branched, cylindrical or ridged, green or purple, sparsely pilose or glabrous, and the stem nodes are prone to adventitious roots. The shape and color of the leaves often vary from species to species, and sometimes they have different leaf shapes on the same plant, usually broad ovoid. Because sweet potatoes are cross-pollinated, self-pollination often does not produce fruit, so sometimes only flowers and no fruit are seen.

Chemical Composition

It mainly contains protein, vitamins, mineral elements, cellulose, anthocyanins, flavonoids and so on.
