Method for breeding dwarfed interstock cherry seedlings

Abstract

The invention discloses a method for breeding dwarfed interstock cherry seedlings. The method includes the first step that daqingye cherry seeds are seeded and grow into seedlings, the seedlings are used as grafting stocks, and cherry dwarfed stocks Gisela Five are used as dwarfed interstocks; the second step that the portions, close to the ground, of the grafting stocks are used for carrying out grafting with the dwarfed stocks Gisela Five, the grafting stocks are used for carrying out budding with the dwarfed stocks Gisela Five from the end of August to the beginning of September in the current year, and grafting between the grafting stocks and the Gisela Five is completed; the third step that Gisela Five bud seedlings pass the winter and sprout and grow long branches in spring of the next year, and when the interstocks bud, the grafting stocks are trimmed at positions 0.5-1 above budding healed wounds in spring of the next year; the fourth step that from May to June of the next year, cherry varieties are connected at positions about 25 cm from the Gisela Five interstocks in a budding mode, interstock leaves are reserved, when the budding varieties bud, the interstocks are trimmed at positions 0.5-1 cm above the budding healed wounds, seedling cultivation can be completed after leaves fall off in the next year, and dwarfed interstock biennial cherry seedling finished products can be bred. The method has the advantages of being high in practicability, low in cost and easy to operate.

Description

technical field [0001] The invention relates to a method for breeding dwarf intermediate stock cherry seedlings. Background technique [0002] For decades, arborization cherry trees have been planted in our country. The trees are tall and bear fruit after seven or eight years, and enter the high-yield period after ten years. The general output is about 1,000 catties. [0003] In recent years, my country has introduced Gisela No. 5 and No. 6 series of rootstocks from Germany. These series of rootstocks have strong dwarfing properties and can only be reproduced asexually. Thus, a method of using Gisela series rootstocks as dwarfing rootstocks to breed dwarf cherry seedlings has been produced. The dwarf cherry seedlings bred by this method first need to establish tissue culture rooms and greenhouses. It is the use of Gisela Series cultivation is carried out in tissue culture rooms and greenhouses, using certain temperature and humidity for tissue culture and cuttings. The tech...

Thus, a method of using Gisela series rootstocks as dwarfing rootstocks to breed dwarf cherry seedlings has been produced. The dwarf cherry seedlings bred by this method first need to establish tissue culture rooms and greenhouses. It is the use of Gisela Series cultivation is carried out in tissue culture rooms and greenhouses, using certain temperature and humidity for tissue culture and cuttings. The technical requirements are relatively high. After surviving, they grow to a certain thickness, and then they are moved to the field, and then grafted with cherry varieties. This method of breeding dwarfs Cherry seedlings belong to the dwarf self-root stock cherry seedlings, which are made of Gisela series rootstocks for tissue culture and cutting, as both the base stock and the intermediate stock, that is, both the root and the dwarfing intermediate stock, although it can bear fruit early, and High yield, its shortcomings are also obvious, there are few vertically downward roots, shallow root distribution, poor ground fixation, support after fruiting, and short tree life
