Abstract

The invention provides a method for fast culturing a new breed of gypsophila. The germchit of the new breed 'yunxing 23' of the gypsophila with excellent performance such as large clusters, white color, a plurality of polyphylls, hard branch, and the like, is obtained by sport deviation selection, selection of implant, sterilization of the implant, induction culture, multiplication culture, successive transfer culture, radication culture and transplantation and survival. The germchit source is sole, the method is easy for control, reproduction speed is fast, and the survival rate of transplantation is up to more than 95%; besides, annual production can be realized in a culturing room, thus saving the land resource, increasing the economic benefit, creating a short approach for culturing the new breed of the gypsophila and effectively shortening the period for culturing the new breed and reducing the cost. The invention also relates to research and improvement on a group-culture and rapid propagation system of the germchit of gypsophila, thus reproduction efficiency is improved, germchit with good quality is obtained, and the production on scale, standardization and industrialization of the germchit of the gypsophila is realized.

Description

technical field [0001] The invention relates to a rapid breeding method for a new variety of baby's breath flower, which belongs to the field of biotechnology. Background technique [0002] Gypsophila paniculata L., also known as Xiacao, Dianthus, and June Snow, is a herbaceous plant of the genus Dianthus in the family Caryophyllaceae. Gypsophila gypsophila has slender stems and luxuriant branches. Numerous small white flowers grow on many slender twigs, like stars, with a very three-dimensional effect. It can be used as a foil for various flower bouquets or flower baskets. It has unique charm and is the world's largest One of the most popular flower arrangements for fresh cut flowers. [0003] In recent years, due to the rapid development of the flower market, the planting area of ​​Gypsophila gypsophila has increased significantly, and the demand for seedlings has also increased accordingly. Most of the Gypsophila seedlings planted in the market are imported from abroad,...
