Abstract

The invention belongs to the technical field of biology, and relates to a method for obtaining regenerated plants by tissue culture of flowers of Amorphophallus bulbifer (Roxb.) Blume. The method comprises the processes of explant disinfection, callus induction, corm like body induction and proliferation, corm like body germination, rooting induction and the like. The method is simple in process,convenient to operate and relatively low in energy consumption; the flowers of Amorphophallus bulbifer (Roxb.) Blume are used as explant materials for induction to obtain callus, and then corm like bodies are obtained by induction and then are proliferated, so that the proliferation efficiency is relatively high; the corm like bodies are cultured into complete plants, and the obtained clone plantsare derived from clean organs without germs or viruses; healthy seedlings (seeds) of Amorphophallus bulbifer (Roxb.) Blume can be efficiently bred in a large scale; the problem of serious shortage ofthe healthy seeds of Amorphophallus bulbifer (Roxb.) Blume in development of the industry of Amorphophallus bulbifer (Roxb.) Blume is solved; and the method has practical significance for promoting development of the industry of Amorphophallus bulbifer (Roxb.) Blume, and has reference value for developing a new way for researching a detoxification technology for seedlings of Amorphophallus bulbifer (Roxb.) Blume.

Description

technical field [0001] The invention belongs to the field of biological technology, and relates to a method for obtaining regenerated plants by plant tissue culture, in particular to a method for obtaining regenerated plants by tissue culture of bulbil bud konjac flower organ. Background technique [0002] Konjac is a perennial monocotyledonous herb belonging to Araceae Konjac, with well-developed underground bulbs. It is the only higher plant found in the plant kingdom that can synthesize glucomannan in large quantities. Its enlarged underground bulbs are rich in glucomannan, starch, Protein, etc. Konjac flour processed by it has good gelling properties, water holding capacity, compounding properties, high viscosity and stability, etc., and is widely used in food, health care, medicine, construction, daily chemicals, oil drilling, etc. field, with extremely high development and utilization value. Konjac has a history of more than 2,000 years of cultivation in my country. A...
