Ever Wonder Where Seedless Fruits Come From?

These days, if we hear about two different plants being combined, the first thing we think of might is modern biotechnology. But the low-technology process of grafting remains an extremely important form of genetic engineering in agriculture. 

Many kinds of plants are grown not from seeds but from pieces cut from existing plants. Farmers cut branches or buds, young growths, from one plant and place them on a related kind of plant. The branch or bud that is grafted is called a scion. The plant that accepts the graft is called the root stock. 

Over time, the parts from the two plants grow together. The grafted plant begins to produce the leaves and fruit of the scion, not the root stock. 

A graft can be cut in several ways. A cleft graft, for example, requires a scion with several buds on it. The bottom of the scion is cut in the shape of the letter V. A place is cut in the root stock to accept the scion. The scion is then securely placed into the cut on the root stock. Material called a growth medium is put on the joint to keep it wet and help the growth.
