Problems solved by technology

At present, the main breeding methods of Dianthus brevifolia are cutting and division breeding, but this breeding method is difficult to achieve a large number of seedlings in a short period of time, and after multiple generations of division, the toxins in the plant will increase, which will affect the robust growth of the plant; and The use of biotechnology tissue culture technology can accelerate its propagation speed and obtain a large number of test-tube seedlings, which can meet the needs of the seedling market

Abstract

The invention discloses a tissue culture and propagation method for brachystemma calycinum, and develops a culture medium used together with the same. By using stems with buds as explants, the method has the advantages of large number of raw materials, and convenience in material accessing. By tissue culture propagation, the culture cycle can be shortened and high-quality seedlings of brachystemma calycinum can be rapidly propagated. The propagation coefficient of 30d buds cultured by the method can reach 6.1 times, the rooting rate of tissue culture seedlings can reach more than 92.6% through expanding propagation, strong seedlings and rooting culture, and the survival rate after transplanting matrix can reach more than 89.5%. Therefore,the method solves the scale seedling problem of brachystemma calycinum, is beneficial to mass production of seedlings, meets market demands, and has a high application value.

Description

technical field [0001] The invention belongs to the technical field of plant tissue culture and propagation, and in particular relates to a method for tissue culture and propagation of Dianthus brevifolia. Background technique [0002] Dianthus short petals, derived from the plant Brachystemma calycinum D.Don of Caryophyllaceae, is a single genus plant of Caryophyllaceae; its root or whole herb is used as medicine and is called Achyranthes bidentata (zhuang), Cramp grass (yao) etc., taste sweet, light, flat in nature; have heat-clearing and detoxifying, relaxing tendons and collaterals, expelling wind and dehumidification, diuresis and detumescence, the effects of osteosynthesis and granulation, used for rheumatic arthralgia, bruises, osteosynthesis, nephritis edema, osteomyelitis, Sore boils, lymph node tuberculosis and other diseases. Dianthus short petals are distributed in Guangxi, Sichuan, Yunnan and other provinces and regions in my country, and are mainly produced in...
