Background

Grafting is one of artificial propagation methods of plants. That is, a branch or bud of one plant is grafted onto a stem or root of another plant, and the two parts joined together are grown into a complete plant. The grafting method is divided into a branch grafting method and a bud grafting method. The grafting is carried out by utilizing the function of wound healing of the plant after being wounded.

In the production practice process, the grafting has very important significance for improving varieties and improving economic value. The grafting has great significance for the propagation of some fruit trees (such as some varieties of persimmon and citrus) which do not produce seeds. The grafting can not only keep the excellent characters of the scion variety, but also utilize the favorable characteristics of the stock to achieve the purposes of early fruiting, enhancing the cold resistance, drought resistance and disease and insect resistance, and also can economically utilize propagation materials and increase the number of seedlings. Is commonly used for the propagation of fruit trees, forest trees and flowers; also can be used for culturing melon vegetable seedlings. The grafting is divided into two categories, namely branch grafting and bud grafting, the former is suitable for the two seasons of spring and autumn, and the survival rate is higher particularly in spring. The latter is preferred in summer.
