Problems solved by technology

The blue skyflower mainly reproduces by bulbs, but the reproduction coefficient is extremely low. In addition, people have been digging extinctly for many years, which has led to the depletion of wild blue skyflower resources.
However, the demand in domestic and foreign markets is increasing year by year, and Qingtiankui is far from meeting the demand of the market.

Embodiment 1

[0019] An example of the rapid propagation method of the blue skyflower corm tissue culture of the present invention, comprises the steps:

[0020] (1) Extraction and disinfection of explants: As the explants, the bulbs of the blue skyflower are sterilized. First, 3-5 drops of detergent are dripped into a beaker with 50ml of tap water, and the explants are put into the beaker and stirred gently. 5min, then use cotton to clean the dirt on the surface of the explant, rinse with tap water for 20-30min; move the ultra-clean bench, soak in 75v / v% ethanol for 30s, rinse with sterile water, and then add 1-2 Sterilize 50ml of Tween-20 with 0.1v / v% mercuric chloride for 1-2min, rinse with sterile water for 3-5 times to obtain sterile explants, wherein the sterile water is distilled water sterilized by high temperature and high pressure ;

[0021] (2) Acquisition of sterile rhizomes: Place the sterilized explants in the induction medium for adventitious bud induction, at a temperature ...

Embodiment 2

[0028] Another example of the rapid propagation method of the blue skyflower corm tissue culture of the present invention, comprises the steps:

[0029] Other conditions are the same as embodiment 1, only the following content is different:

[0030] In step (3), the integrated medium for rhizome propagation and bulb induction is 1 / 2MS as the basic medium, and 5g·L-1 agar, 25g·L-1 sucrose, 1.5mg·L-1 of 6 - benzyl adenine, kinetin (KT) 0.3mg L-1, naphthaleneacetic acid 0.3mg L-1, pear juice 100g L-1, medium pH value 6.8; corm induction coefficient 22.

[0031] In step (4), the transplanting survival rate was 94%.

Embodiment 3

[0033] Another example of the rapid propagation method of the blue skyflower bulb tissue culture of the present invention comprises the following steps:

[0034] Other conditions are the same as embodiment 1, only the following content is different:

[0035] In step (3), the integrated medium for rhizome propagation and bulb induction is 1 / 2MS as the basic medium, and 5g·L-1 agar, 25g·L-1 sucrose, 1.5mg·L-1 of 6 - Benzyl adenine, kinetin (KT) 0.5 mg L-1, naphthalene acetic acid 0.5 mg L-1, pear juice 150 g L-1, medium pH 6.8; corm induction coefficient 24.4.

[0036] In step (4), the transplanting survival rate was 91.5%.

Abstract

The invention discloses a method for quickly propagating nervilia fordii corms by tissue culture. The method is characterized by comprising steps of (1), drawing and disinfecting explants; (2), acquiring aseptic rhizomes; (3), carrying out rhizome propagation and corm induction integral culture; (4), carrying out seedling exercising and transplanting on corms. Compared with the prior art, the method in the technical scheme has the advantages that the nervilia fordii corms can be quickly propagated by tissue culture by the aid of biotechnologies, accordingly, large quantities of nervilia fordiiseedlings which can be cultivated in fields can be bred within a short time, the propagation coefficients of the nervilia fordii seedlings can be obviously increased, the seedling quality of the nervilia fordii seedlings can be obviously improved, the nervilia fordii corms can be produced on a large scale, and the production requirements can be met.

Description

technical field [0001] The invention relates to a rapid propagation method for tissue culture of blue skyflower bulbs. Background technique [0002] Blue Sky Kwai is the leaf or bulbous leaf of orchid plant Nerviliafordii (Hance) Schitr, also known as unifoliate, uniped lotus, pearl leaf, falling jack, iron hat, samosa, and green lotus. Flat in nature, bitter in the mouth, sweet, cool. Astragalus is a rare and endangered plant in my country. It has the functions of clearing the lung and relieving cough, strengthening the spleen and eliminating stagnation, clearing away heat and detoxification, eliminating stagnation and dispelling pain. Scrofula, sores, swollen toxins, bruises, etc. The blue skyflower is mainly propagated by bulbs, but the reproduction coefficient is extremely low. In addition, the extinction-style excavation by people over the years has led to the depletion of wild blue skyflower resources. However, the demand in domestic and foreign markets is increasing...
