Problems solved by technology

This culture method not only has the problems of long induction culture period and high cost, but also has the problem that the culture material is prone to cell variation during the long-term culture process, making it difficult to ensure the stability of the original species
At present, there is no report of obtaining regenerated plants by cultivating Fritillaria fritillaria embryoids

Abstract

The invention discloses a method for inducing generation of fritillaria cirrhosa embryoids, belonging to the technical field of biologics. The method comprises the following steps of selecting tender leaf sheath of a fritillaria cirrhosa plant as an explant, sterilizing, subsequently carrying out callus induction, grafting the callus into an MS (Mass Spectrometry)+cefotaxime sodium culture medium, culturing for 50 days to grow embryoids on the surface of the callus, further cutting down the embryoids taking 1-3 embryoids as one group, grafting into a rapid growth culture medium with 0.1-1mg.L<-1> MS+6-BA+100-450mg.L<-1> cefotaxime sodium, culturing for 60 days under the condition that the culture temperature is 15-25 DEG C, the embryoids are shined for 6-20 hours every day, and the shining intensity is 800-2,500lx, so as to grow the embryoids into green small fritillaria cirrhosa plants. According to the method, the fritillaria cirrhosa embryoids can be induced by utilizing antibiotic chemical factors of a certain concentration, and a novel way is provided for breeding of the fritillaria cirrhosa embryoids.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for inducing the embryoid body of Fritillaria fringiosa to produce. Background technique [0002] Fritillaria cirrhosa D.Don is a perennial herb of Liliaceae. Its bulbs are used as medicine. It grows at an altitude of 3500m~4500m. It is mainly produced in Sichuan, Tibet, Yunnan and other provinces. Chuan Fritillaria likes cold and cool climate conditions, and has the characteristics of cold resistance, humidity, high temperature, and shade. Chuan Fritillaria is an important good medicine for treating cough. It is used for symptoms such as lung heat dry cough, dry cough with little phlegm, yin deficiency and labor cough, and expectoration with blood. Fritillary fritillary plants grow in alpine shrubs or grasslands at an altitude of 2800-4700m, and mainly rely on seeds for sexual reproduction. However, because of the morphology and physiological after-ripening cha...
