The origin of sunflower

Sunflower, scientific name sunflower. According to research, it is native to Peru, and it is said that there are still wild sunflowers growing in Peru. Sun God in Greek means sun and flowers. Around 300 AD, Indians in the North American continent first planted sunflowers artificially, and used them as crops to make bread and snacks, and used sunflowers as medicinal materials to treat snake bites. Ornamental sunflowers are native to Peru and are called "Peruvian Chrysanthemum" locally. At the end of the 15th century, Spanish explorers crossed the ocean and brought sunflowers from America to Europe. Europeans developed sunflowers, 1769 used to extract oil and cultivate ornamental sunflowers. Since then, they have spread all over the world through Peru. Around 300 AD, North American Indian tribes planted sunflowers in what is now Arizona and New Mexico. They cultivated wild multi-corolla sunflowers into single-corolla sunflowers. Some archaeologists believe that sunflowers became plants earlier than corn. Europeans developed sunflowers around16th century, and Spanish explorers brought this kind of sunflowers to Europe. Soon, it was widely planted in western Europe, but it was mainly used for viewing. 1769, sunflower is used to extract oil. By 1830, merchants began to produce sunflower oil on a large scale. In the early19th century, Russian farmers planted 2 million acres of sunflowers. At that time, sunflowers were mainly divided into oil sunflowers and edible sunflowers. The government also began to study sunflowers. V.S. Pustovoit planted sunflower on a large scale in Krasnodar, and achieved remarkable results, greatly increasing the oil content. Today, the highest achievement award of sunflower research in the world is named Pustovoit Award. Sunflowers Return to North America/KLOC-In the late 9th century, Russian sunflower seeds began to be introduced to the United States. By 1880, "Russian sunflower seeds" have appeared in the product catalogs of some American seed companies. It is likely that Russian immigrants at that time brought sunflower seeds to North America. In the United States, the earliest use of sunflower in agricultural production is as silage. 1926, Missouri Sunflower Growers Association began to use sunflower seeds to extract oil. By the end of 1970s, due to the growing demand for sunflower oil in Europe, the planting area of sunflower in the United States exceeded 5 million acres. For health reasons, people are reluctant to use animal fats such as butter for cooking because the fat content is too high. Russian sunflower oil once dominated the European market, but the rapid growth of demand made the Russians unable to meet the market demand, which provided a rare opportunity for the development of sunflower seed industry in the United States. Today, western European countries are still the concentrated areas of sunflower oil consumption, but their own production has basically met the demand, and the number of sunflower oil and sunflower seeds exported to Europe by the United States has been very small. After several twists and turns, the sunflower originated in North America has returned to its "hometown". Indians and Russians completed the early genetic modification of this sunflower, and Americans hybridized it, eventually forming the sunflower crop we see today. If these predecessors are still alive, they will be proud of their contribution to today's commercial sunflower.
