Einkorn

life science Maturity 9-11 Next article →

Einkorn is a very special type of wheat. Its name comes from a German word that means "single grain." This name describes how the plant grows. Each tiny part of the plant holds only one single grain.

This wheat is very important to history. It was one of the first types of wheat that humans ever grew. It is a "covered wheat," which means the seeds have tough husks called glumes. These husks wrap tightly around the grain. This makes it a hard job to separate the shell from the seed.

There is a big difference between wild einkorn and the kind people grow. In the wild, the plant head shatters when it is ripe. This causes the seeds to drop onto the ground. Dropping seeds helps new plants grow in the wild. However, the kind humans grow is different. The seed head stays intact even when it is ripe. This happens because of a change called a mutation.

This change makes the wheat much easier for humans to harvest. People can pick the whole head and then break it apart by hand. Because humans plant and harvest it, the domestic kind stays alive.

Humans have a long history with this grain. Some evidence from Syria shows people gathered it 30,000 years ago. Scientists believe it was first domesticated about 10,000 years ago. This happened during the Pre-Pottery Neolithic periods. DNA tests suggest it was first grown near Karaca Dağ in southeast Turkey. Some people think growing einkorn helped support the nearby site of Göbekli Tepe.

The process of changing the plant likely took only 20 to 200 years. This was possible because the plants mostly pollinate themselves. This helped the good traits stay the same.

Many scientists have studied einkorn over many years. Carl Linnaeus described the cultivated form in 1753. He called it Triticum monococcum. Other experts gave it different names later on. For example, von Bieberstein named it Triticum pubescens in 1800. Clementi used the name Triticum hornemanii in 1818. The wild version is known as Triticum boeoticum.

These names help scientists keep track of different types. It is a diploid species, which means it has 14 chromosomes. Unlike bread wheat, einkorn is not a hybrid.

Einkorn is a very hardy plant. It can grow in poor or dry soil where other wheat fails. People eat it in many ways today. You might eat it boiled in a bowl of porridge. It is also used to make bulgur. It is a very nutritious food. It has more protein than some modern red wheats. It also has more fat, potassium, and beta-carotene.

Scientists even use it to help other wheat stay healthy. It has special genes that help plants fight off diseases like rust.
