But many crops do not come from seeds. Many kinds of trees and plants are grown from __36__cur from existing trees and plants. This is called grafting ( 嫁接 ). Framers cut branches or young growths, called__37__, from one plant and place them on a related kind of plant. The branch or bud that is grafted is called a scion ( 接穗 ). The plant that__38__the graft is called the root stock. Over time, the__39__from the two plants grow together. The grafted plant begins to __40__the leaves and fruit of the scion, not the root stock. A graft can be cut in several ways. A cleft graft ( 割接,劈接 ), for example, requires a scion with several buds on it. The bottom of the scion is cut in the__41__of the letter V. A place is cut in the root stock to accept the scion. The scion is then __42__placed into the cut on the root stock. Growth medium is put on the __43__to keep it wet and help the growth. Grafting can join scions with __44__qualities to root stock that is strong and resists disease and insects. Some common fruit trees such as sweet cherries have to be grafted. In an age of high-technology agriculture, grafting is a low-technology method that remains__45__important.
