The plant that【S3】______the graft is called the root stock. Over time, the【S4】______from the two plants grow together, the grafted plant begins to【S5】______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【S6】______of the letter V. A place is cut in the root stock to accept the scion. The scion is then【S7】______placed into the cut on the root stock. Growth medium is put on the【S8】______to keep it wet and help the growth.
Grafting can join scions with【S9】______qualities to root stock that is strong and resists disease and insects. Some common fruit trees such as sweet cherries have to be grafted.
