Rapid grafting method for atemoya

Abstract

The invention discloses a rapid grafting method for atemoya. The method comprises the following steps that tender stems with internodes of the atemoya are selected as explants, disinfection, callus culture, subculture and rooting culture are carried out so as to obtain tissue culture seedlings, then the tissue culture seedlings are subjected to seedling hardening so as to rootstocks; branches of the atemoya are selected as scions; and before grafting, the scions are firstly put into a disinfectant to be disinfected and are put into a rooting culture medium to be soaked, then the scions are grafted onto the rootstocks by adopting a conventional cut grafting method and then are wrapped by using plastic films, and then the grafted seedlings are managed by using a conventional method. The rapid grafting method has the advantages that the atemoya seedlings obtained by grafting can guarantee the excellent variety characteristics, the survival rate of the grafted seedlings can reach 92% or above, in addition, the operation is simple, the cost is low, the grafting time is obviously shortened, the application prospect is wide, and a powerful technical support is provided for accelerating the rapid development of the atemoya industry.

Description

technical field [0001] The invention belongs to the technical field of nursery stock propagation, and in particular relates to a rapid grafting method of pineapples. Background technique [0002] Pineapple custard, also known as pineapple custard or honey custard, is mainly produced in Taitung, Taiwan. With the strengthening of agricultural science and technology exchanges and cooperation between Guangxi and Taiwan in recent years, pineapple custard has begun to be favored by people from all walks of life. Currently, Guangxi The central and southern regions have shown a trend of large-scale planting. Pineapple Sakyamuni has high nutritional value, rich in protein, and also contains a variety of vitamins, a large amount of carbon carbohydrates, and also contains a large amount of calcium, phosphorus, iron and other nutrients. At the same time, Sakyamuni pineapple meat also contains some substances called "annon apple lactone". These substances have strong anti-tumor activity...

Problems solved by technology

[0004] When it is high, it can be planted in separate beds or moved into nutrient bags. It can be planted after one year of cultivation. This method not only slows the propagation speed but also is difficult to maintain good traits

Grafting and propagation can ensure that the offspring maintain the excellent traits of the mother tree. At present, the seedlings obtained by sowing are mainly used as rootstocks. After the seedlings grow to a certain height, they are grafted to the scion. This method has a slow propagation speed and is difficult to meet the current market demand.
