Abstract

The invention provides a rapid breeding method for Caesalpinia cucullata Roxb. According to the method, tissue like a stem of Caesalpinia cucullata Roxb. is cultured on an N6 culture medium, and a rhizome with one or two buds is exactly taken as an explant, then disinfected and inoculated into a culture medium consisting of N6, 0.5 mg / L of 2,4-D, 1.4 mg / L of 6-BA and 0.4 mg / L of IBA for culture; the bud germinates in about 6 to 8 days after inoculation, and a young seedling with leaves is formed in about 10 days; the young seedling is cut down and inoculated into a culture medium consisting of N6, 0.1 mg / L of 2,4-D, 1.8 mg / L of 6-BA and 0.4 mg / L of IBA so as to maintain high-speed progressive increase, and a propagation coefficient is more than 5; a culture medium consisting of N6, 0.5 mg / L of 6-BA and 1.5 mg / L of NAA is selected as a rooting medium, a rooting rate reaches more than 90%, and a complete plant is formed in only about 25 days; and a test-tube plantlet is transplanted into sandy soil, attention is paid to water retention and moisture retention, a transplanting survival rate reaches more than 90% in one month after transplanting, and a high frequency stable regeneration system is established. The method provided by the invention has the advantages of fast budding, a high propagation rate, simpleness, low production cost, capacity of batch production and a high application value.

Description

technical field [0001] The invention relates to the field of bioengineering, and relates to plant tissue culture technology, in particular to a tissue culture method of Jianxuefei. Background technique [0002] Plants are a natural treasure house of medicines. People have a long history of using medicinal plants. About 75% of the world's population uses plants as a source of medicine for treating and preventing diseases (Xing Jianmin, 2001). Humans have discovered many drugs with high physiological activity from plants, and the drugs derived from plants account for more than 25% of the total amount of drugs (Zheng Guangzhi, 1987). Our country's traditional Chinese herbal medicine has a history of thousands of years, and it is still widely used in our country and many countries and regions. However, because the traditional method of obtaining Chinese herbal medicine is at the cost of collecting and consuming a large amount of wild plant resources, when the amount of collecti...
