Problems solved by technology

However, since different plants have different sensitivities and resistances to the same infection virus, and different viruses are selective for the infected host plants, and the callus often undergoes some mutations after multiple subcultures, resulting in different host plants and different viruses. The detoxification methods and detoxification effects are not the same
Although potato, sweet potato, garlic, banana, citrus, apple, grape, lily, strawberry, petunia, carnation, rose, chrysanthemum, peony, taro, camellia, sugarcane, strawberry, etc. Widely used in China, but detoxification of lingonberry has not been reported

Abstract

The invention provides a cowberry detoxification breeding method. The cowberry detoxification breeding method comprises the following steps: accelerating germination of cowberry resting shoots, shearing off a bud when the length of the bud reaches 1-3 cm and carrying out sterilizing treatment; cutting off 0.3-0.8 cm of a stem tip from the sterilized bud, and inoculating the stem tip on a foundational medium, and culturing under the conditions that the temperature is 25-28 DEG C, the illumination intensity is 1,800-2,200 Lx, and the illumination time is 12-16 h / d; after the stem tip grows until the length of the stem tip reaches 1.5-2.0 cm, cutting off 0.03-0.05 cm of a stem tip in a sterile environment and inoculating the stem tip to a detoxification medium, carrying out dark culture for 5-9 days at the temperature of 22-25 DEG C, and continuing culturing in an environment in which the temperature is 23-26 DEG C, the illumination intensity is 1,800-2,200 Lx and the illumination time is 12-16 h / d; and inoculating a detoxification seedling to a medium, carrying out rapid multiplication culture, and then carrying out seedling hardening and rooting after the length of the seedling reaches 2.0-3.0 cm.

Description

technical field [0001] The invention relates to the technical field of plant virus-free culture and rapid propagation, in particular to a method for breeding virus-free cranberry seedlings and a virus-free culture medium. Background technique [0002] In actual production, many asexually propagated plants can be infected by viruses. Vaccinium is propagated by creeping rhizomes formed by the mother plant, and seedlings are susceptible to viruses during growth. Viruses can cause devastating damage to parasitic bilberry, resulting in Substantial reduction in production, or even the death of the whole plant, will also lead to the degradation of the species and the deterioration of the quality. It is the basic requirement of actual production and breeding to keep the excellent characteristics of varieties well. Therefore, it is very important for cranberry production to seek a treatment method that can not only maintain the excellent characteristics of varieties but also get rid ...
