The origin and development of tomato;

The wild ancestor of tomato is Solanum pimpinellifolium, which is native to the Andes in western South America (now Peru, Ecuador and Bolivia). These wild species are as big as peas, weigh only 1-2g, and have a strong sour taste. Occasionally, birds spread tomato seeds to Mexico through feces.

The earliest cultivation records can be traced back to at least 500 BC, and the evidence of domestication points to the Aztecs and other peoples in Central America. Spanish missionary Desa Argonne recorded in detail the grand occasion of selling all kinds of tomatoes and their products in the market in tenochtitlan (now Mexico City), the capital of Aztec Empire.

In France, Italy and northern Europe, tomatoes were originally planted as ornamental plants. In Britain, Dr. John Gerald first planted tomatoes in the 65438+90' s.
