薯类作物主要包括甘薯(Ipomoea batatas)、马铃薯(Solanum tuberosum)、木薯(Manihot esculenta)和山药(Dioscorea ssp.)等,归属不同的科属,其收获的产品器官是地下储藏根(storage root)或块茎(tuber)。在英文中没有直接与“薯类”对应的词汇,以“root and tuber crops”翻译最为合适,因此用“根茎类作物”更为恰当。甘薯的拉丁学名中种加词“batatas”即为印度群岛阿拉瓦克人(Arawak)对甘薯的叫法;而马铃薯学名中的“tuberosum”意为“膨大的”。这些薯块常常富含淀粉,间或富集胡萝卜素和花青素等次生代谢营养物,是植物最常见的变态器 Potato crops mainly include Ipomoea batatas, Solanum tuberosum, Manihot esculenta and Dioscorea ssp., Belong to different families, and the harvested plant organs are underground storage roots, Or tuber. In English, there is no direct term corresponding to “potato”, most suitable for translation of “root and tuber crops”, so “rhizome crop” is more appropriate. The Latin name for sweet potatoes, “batatas”, is the name for sweet potato in the Arawak Indies, while “tuberosum” in potato names means “bloated.” These tubers are often rich in starch, occasionally enriched with secondary metabolic nutrients such as carotenoids and anthocyanins, and are the most common metamorphoses of plants
