What do sweet potatoes and potatoes belong to?

The reproduction of sweet potato, also known as sweet potato, sweet potato and potato belongs to asexual reproduction. ? The propagation of sweet potato is to germinate long seedlings with adventitious buds lurking under the skin around tubers, and then cut them in the field, or cut them in the nursery for propagation, and then cut them in the field from the nursery. Potatoes are cut into blocks according to the eyes of tubers, and both of them belong to asexual reproduction.

Seed propagation is rarely used in general production, and it is mainly used to cultivate excellent new varieties. Because sweet potatoes are cross-pollinated, self-pollination is often not fruitful, and sometimes only flowers are not. However, the seeds of potato are too small, 1g is about 1600 ~ 2000. If the potato (seedling potato) is directly sown with seeds, it is not easy to get the whole seedling, the character is unstable and the variety is difficult to maintain.

Using tuber asexual propagation is not only conducive to maintaining the Excellence of its original varieties, but also convenient for cultivation and management, shortening the growth period and easily obtaining high yield. Therefore, artificial cultivation of sweet potato and potato usually adopts the method of asexual reproduction.
