什么是花生

The domesticated peanut is an amphidiploid or allotetraploid, meaning that it has two sets of chromosomes from two different species.驯化的花生是一种二倍体或异四倍体，这意味着它具有来自两个不同物种的两组染色体。 The wild ancestors of the peanut were thought to be A. duranensis and A. ipaensis, a view recently confirmed by direct comparison of the peanut's chromosomes with those of several putative ancestors.This domestication might have taken place in Argentina or Bolivia, where the wildest strains grow today.花生的野生祖先被认为是du.rananensis和A.ipaensis，最近通过直接比较花生的染色体与几个假定祖先的染色体而证实了这种观点。这种驯化可能发生在最野生的阿根廷或玻利维亚如今，压力越来越大。 In fact, many pre-Columbian cultures, such as the Moche, depicted peanuts in their art.实际上，许多前哥伦布时期的文化，例如Moche，都在其艺术作品中描绘了花生。
Evidence demonstrates that peanuts were domesticated in prehistoric times in Peru.有证据表明，花生是在史前时期在秘鲁驯化的。 Archeologists have (thus far) dated the oldest specimens to about 7,600 years before the present.Cultivation spread as far as Mesoamerica where the Spanish conquistadors found the tlalcacahuatl (Nahuatl = "cacao", whence Mexican Spanish, cacahuate and French, cacahuète) being offered for sale in the marketplace of Tenochtitlan (Mexico City).考古学家迄今（迄今）已对最古老的标本进行了追溯，距今已有约XNUMX年的历史。耕种一直延伸到中美洲，西班牙征服者在那里发现了tlalcacahuatl（纳瓦特尔=“ cacao”），在那里提供了墨西哥西班牙语，cacahuate和法语，cacahuète。在Tenochtitlan（墨西哥城）的市场上出售。 The plant was later spread worldwide by European traders.该工厂后来被欧洲贸易商遍及全球。
The legume gained Western popularity when it came to the United States from Africa.从非洲来到美国，这种豆科植物在西方很受欢迎。 It had become popular in Africa after being brought there from Brazil by the Portuguese around 1800.它在XNUMX年左右被葡萄牙人从巴西带到非洲后开始在非洲流行。
