A, cutting, showing two nodes and a bud at each node. B, cutting, showing a new plant which has developed from a bud at the node. Adapted from N. A. Cobb. When grafting is successful, the cion becomes as closely related to the activities of the stock as ordinary branches are. Through the stock the cion receives water and mineral elements from the soil, while the stock receives some of the foods made by the leaves of the cion. However, with all of this close connection, the nature of both stock and cion remains in most cases practically unchanged and each, therefore, continues to produce fruit unchanged in type. This feature is important for two reasons. First, it enables one to combine the desirable features of two plants into one individual where the desirable features, although remaining unchanged in nature, may assist each other in functioning. Some fruit trees bear delicious fruit, but on account of poor root systems or other.
