Problems solved by technology

However, this patent-applied technology only involves the roots of Panax notoginseng, and does not involve the induction of adventitious roots from callus from the flower buds, leaves, petioles, stems and fibrous roots of field cultivated Panax notoginseng, nor does it involve the direct induction of regenerated seedlings of Panax notoginseng The method of adventitious roots, but the induction of Panax notoginseng is not only limited by the place of origin and cannot meet the needs of various places, but also grows slowly and is seriously polluted by endophytic fungi; this technology does not involve the analysis of adventitious root induction rate and main active ingredients saponins, and Method for establishing liquid culture system not involving adventitious roots

Embodiment 1

[0023] Example 1: Induction of Panax notoginseng adventitious root in vitro and establishment of liquid culture system

[0024] Take the callus pieces induced from the stem explants of Panax notoginseng, place them on MS (containing 10mmol / L ammonium nitrate) solid medium supplemented with 2mg / L indolebutyric acid and 0.7mg / L kinetin, and place them at 25°C Adventitious roots formed after 20 days of induction under sterile light-proof conditions. Take the above-mentioned induced adventitious roots, transfer them together with the parental callus to MS liquid medium containing the same composition, and continuously subculture for 3 generations at 26°C with 28 days / generation interval (shaking table speed 100r / min). Adventitious roots were cultured separately from parent tissues. Take the isolated and cultured adventitious roots and transfer them to MS liquid medium containing 5mg / L indole butyric acid, and culture them in the dark at 80r / min at 25°C for 35 days to obtain the a...

Embodiment 2

[0026] Example 2: In vitro induction of Panax notoginseng adventitious root and establishment of liquid culture system

[0027] Take the callus pieces induced from the leaf explants of Panax notoginseng, place them in solid MS (containing 10mmol / L ammonium nitrate) containing 0.1mg / L indolebutyric acid, 5mg / L naphthaleneacetic acid and 0.1mg / L kinetin On the culture medium, adventitious roots formed after being induced for 35 days at 20°C under sterile and dark conditions. Take the adventitious roots induced above, and transfer them together with the parental callus to the MS liquid medium containing the same composition, and continuously subculture at 20°C for 4 generations at an interval of 21 days / generation (shaking table speed 120r / min). Adventitious roots were cultured separately from parent tissues. Take the isolated and cultured adventitious roots and transfer them to MS liquid medium containing 5mg / L naphthaleneacetic acid, and culture them in the dark at 120r / min at...

Embodiment 3

[0029] Example 3: In vitro induction of Panax notoginseng adventitious root and establishment of liquid culture system

[0030] Take the callus pieces induced from the explants of the petiole of Panax notoginseng, put them on the solid medium of MS (containing 5 mmol / L ammonium nitrate) containing 10 mg / L indolebutyric acid and 0.1 mg / L kinetin, at 25 °C Adventitious roots formed after 35 days of induction under sterile and dark conditions. Take the adventitious roots induced above, and transfer them together with the parental callus to the MS liquid medium containing the same composition, and continuously subculture at 26°C for 5 generations at an interval of 35 days / generation (shaking table speed 80r / min). Adventitious roots were cultured separately from parent tissues. The adventitious roots that were isolated and cultured were transferred to MS liquid medium containing 0.1mg / L indolebutyric acid and 5mg / L naphthaleneacetic acid, and cultured in the dark at 120r / min at 25...

Abstract

A method for inducing the adventitious root of notoginseng and its tissue culture includes such steps as taking the callus and explant of notoginseng, putting them on the fixing culture medium MS containing one or more of indole-butanoic acid, naphthylacetic acid and kinetin, inducing adventitious root in aseptic and dark condition, transferring the induced adventitious root and its mother tissue the liquid MS culture medium, culturing, separating the adventitious root from its mother tissue, and culturing the adventitious root in liquid MS culture medium containing indole-butanoic acid and / or naphthylacetic acid.

Description

technical field [0001] The invention relates to a method in the technical field of medicines, in particular to a method for inducing and tissue-culturing Radix Notoginseng adventitious roots. Background technique [0002] Panax notoginseng is one of the unique, precious and most commonly used Chinese herbal medicines in my country. It has the functions of dispelling blood stasis, stopping bleeding, reducing swelling and relieving pain. Important raw materials for health care products and medicines, such as Xuesaitong, Yunnan Baiyao, Compound Danshen Dripping Pills and Compound Sanqitongluo Tablets, etc. However, due to the limitation of its growth by geographical conditions and the influence of "cultivated land cannot be reused", the cultivated area is very limited, resulting in a shortage of medicinal materials, which cannot meet the needs of the medical care market. In order to solve the problem of shortage of land resources and non-reuse of land resources, it is urgent to...
