Remarks:

Sweet potatoes are mainly eaten as fat tubers. The shape, size, skin and flesh color of the roots vary depending on the variety and cultivation conditions. The shape is divided into spindle, cylindrical, spherical and block-shaped; the skin color is white, yellow, red, light red, purple and other colors; the flesh color can be divided into white, yellow, light yellow, orange or with purple halo, etc. . The outer layer of the tuber is the skin containing anthocyanins, commonly known as potato skin. The several layers of cells below the epidermis are the cortex, and the inner side is the edible central column. There are many vascular bundle groups in the central column, as well as primary, secondary and tertiary cambium, which are continuously differentiated into phloem and xylem. At the same time, the xylem differentiates into secondary and tertiary cambial layers, and again differentiates into tertiary and tertiary vessels, sieve tubes and parenchyma cells. As the secondary cambium continues to differentiate into a large number of parenchyma cells and is filled with starch granules, the roots expand rapidly. The phloem in the central column has milk tube cells, which are initially limited to the outside of the phloem. Later, because various cambium layers can produce new milk tubes, they spread throughout the root tuber. The white pulp that flows out when the root tuber is cut is the milk secreted by the tuber tube. , containing purpurin.
