Description
Technical Field
The invention relates to the technical field of tissue culture and propagation, in particular to a tissue culture method of radix sophorae flavescentis.
Background
Radix Sophorae Flavescentis, radix Stemonae and radix Sophorae Flavescentis, which is one of the main drugs in YA YAJIAO HAIDU powder, is the dry root of herba Eichhorniae saddle of the genus Ecliptae of the family Asclepiadaceae, and is widely used in Yunnan and Guangxi provinces for treating dysentery, diarrhea due to damp-heat, heart and stomach pain, common cold and fever, chronic gastritis, traumatic injury, etc.
In the prior art, the propagation method of the vine radix sophorae flavescentis generally adopts seed propagation, layering propagation, tissue culture and the like; the propagation of the sophora vine seeds is time-consuming and labor-consuming, seedlings can emerge in 30 to 40 days, the seedlings can be transplanted after 2 to 3 years, and the time for growing the sophora vine seeds into medicinal materials is longer. The survival rate of layering propagation of the radix sophorae flavescentis is low, and standardized planting is not facilitated. The tissue culture (rapid propagation) efficiency of the vine radix sophorae flavescentis is high, and the tissue culture method is simple, convenient, easy, quick in effect taking and good in effect, so that the tissue culture method is recommended to be adopted in production. Once the tissue culture seedling of the sophora flavescens is survived, the drought resistance is strong after the root is deeply pricked, and the environment survival ability is strong.
Therefore, how to provide a tissue culture method capable of significantly improving the quality of a tissue culture seedling of radix sophorae flavescentis is a technical problem to be solved urgently by the technical personnel in the field.
Disclosure of Invention
In view of this, the invention provides a method for tissue culture of sophora moorcroftiana, which uses plant growth regulators with different concentrations at different development stages of sophora moorcroftiana, so as to significantly improve the number and quality of buds, differentiated buds and seedlings of sophora moorcroftiana, and improve the survival rate of tissue culture.
In order to achieve the purpose, the invention adopts the following technical scheme:
a tissue culture method of radix sophorae flavescentis comprises the following steps:
1) And (3) explant sterilization: pretreating the fruit pods of the radix sophorae flavescentis, taking out seeds in the fruit pods, and disinfecting the seeds for later use;
the process of pretreating the fruit pods of radix sophorae flavescentis and disinfecting the seeds comprises the following steps:
11 Washing the fruit pod of radix Sophorae Flavescentis with sterile water for 3 times, each for 1-2 min;
12 Taking out the seeds in the fruit pods of the vine and lightyellow sophora root, soaking the seeds in 75% alcohol for 20-30s, and then washing the seeds with sterile water for 3 times, each time for 1-2 minutes;
13 Soaking the seeds treated in the step 12) with 0.1 percent mercuric chloride for 10-15min, and then washing with sterile water for 4-5 times, 1min each time for later use;
2) Seed germination culture: inoculating the seeds sterilized in the step 1) into an MS culture medium added with 0.8-2.0mg/L6-BA, 0.2-0.5mg/L LNAA and 1g/L active carbon for germination culture, and obtaining vine sophora flavescens sprouts after 20-25 days;
3) And (3) differentiated culture of cluster buds: inoculating the stem lightyellow sophora root sprouts obtained in the step 2) into an MS culture medium added with 3.0-4.0mg/L6-BA and 0.2-0.5mg/LNAA for differential culture, and obtaining stem lightyellow sophora root differentiated sprouts after 35-45 days;
4) Rooting and seedling strengthening culture: when the stem sophora flavescens differentiated bud in the step 3) grows into 3-4cm seedlings, transferring the stem sophora flavescens differentiated bud into an MS culture medium added with 1.0mg/LNAA and 1g/L of activated carbon to carry out rooting and seedling strengthening culture, and obtaining rooted seedlings after 45-55 days;
5) Hardening and planting: culturing the rooted seedlings obtained in the step 4) in natural light for 3 days, opening the bottle caps of the test tube seedlings, hardening the seedlings for 3 days, then slightly clamping the test tube seedlings by using forceps, washing off agar at the base part, transplanting the test tube seedlings into sandy soil added with 1/2MS nutrient solution, transplanting the test tube seedlings into soil after 4 weeks, and performing field planting.
The technical effect achieved by the technical scheme is as follows: in the tissue culture, the reasonable matching of hormone and auxin is the key for achieving the optimal culture effect, and in the stages of seed germination, cluster bud differentiation, rooting and seedling strengthening, plant growth regulators with different concentrations are added into an MS solid culture medium, so that 6-BA and NAA with specific concentrations have a synergistic interaction effect, the germination rate and cluster bud differentiation amount are obviously improved, and the seedling quality is improved;
in the process of plant rooting culture, the light irradiation time is properly increased to be beneficial to the rooting of the plantlets, but the direct irradiation of the roots by strong light can inhibit the growth of the roots, so that the active carbon is added into the rooting and strong seedling culture medium to provide a dark rooting environment and prevent browning; the active carbon can also adsorb some harmful substances released in the growth process of plants, and is beneficial to the growth of seedlings.
The activated carbon can adsorb some harmful substances released in the growth process of plants, so that the seedlings grow strongly by adding the activated carbon in the rooting and strong seedling culture stage in the experiment.
As a preferable technical scheme of the invention, in the steps 2) -4), the temperature of the culture room is 23-27 ℃, the illumination intensity is 1000-1200lx, and the illumination is 12-14h every day.
The technical effect achieved by the technical scheme is as follows: and (3) promoting the rooting and seedling growing of the plant at proper temperature, illumination intensity and time, and otherwise, inhibiting the production of the culture tissue by strong illumination if the temperature is too high or too low.
As a preferred technical scheme of the invention, in the steps 2) to 4), the pH value of the MS culture medium is controlled to be 6.2 to 6.7 (measured by a precision pH test paper).
According to the technical scheme, compared with the prior art, the tissue culture method for the radix sophorae flavescentis provided by the invention has the advantages that the germination rate, the growth amount of the buds, the differentiation amount of the cluster buds, the number and the quality of seedlings of the radix sophorae flavescentis seeds are obviously improved;
moreover, stem tips, cotyledons, leaves and the like are selected as the explants for tissue culture of other plants in the same family, the stems and leaves of the bittersweet root have milk and are densely covered with villi, and the explant is selected in consideration that the stem tips are taken and are not easy to sterilize, and the injury of the explant can release the milk to influence the survival rate of the explant after being inoculated to a culture medium and the like.
