Embodiment 1

[0053] The mountain grape variety Beibinghong was used as the test material, which was obtained from the National Fruit Tree Germplasm Zuojia Mountain Grape Resource Garden of the Institute of Special Products, Chinese Academy of Agricultural Sciences. Take the branches of Vitis vinifera and carry out germination culture in water, cut off the 1-year-old new shoots with 4 to 5 leaves, remove the leaves, cut into single-bud stem sections about 2cm long, and then put these single-bud stem sections into a small amount Shake in washing powder water for 10 minutes, rinse with running water for 20 minutes, disinfect the surface with 0.1% mercuric chloride on the ultra-clean workbench for 3 minutes, rinse with sterile water for 5 times, and cultivate according to the following steps. The specific steps are as follows:

[0054] (1) Induction culture: Inoculate the 2cm-long single-bud stem section of Vitis vinifera after disinfection and washing into the induction medium, and the culture...

Embodiment 2

[0064] The mountain grape variety Zuoyouhong was used as the test material, and the material was obtained from the National Fruit Tree Germplasm Zuojia Mountain Grape Resource Garden of the Institute of Special Products, Chinese Academy of Agricultural Sciences, and the mountain grape seedlings were cultivated according to the method steps described in Example 1.

[0065] Wherein, during the culturing process of Vitis vine seedlings in this example, the conditions for the induction culture are 23°C room temperature, 16h / d light hours, 2500Lx light intensity, and 50% indoor humidity, and the induction culture time is 25 days.

[0066] In the induction medium, the content of each component is 0.5 mg / L of 6-benzylaminopurine, 0.001 mg / L of naphthaleneacetic acid, 7.5 g / L of agar, 30 g / L of sucrose, and 0.8 g / L of activated carbon. L, the pH of the induction medium was 6.0.

[0067] In this example, the culture medium and culture conditions used in the rest of the culture steps ar...

Embodiment 3

[0069] The mountain grape variety Shuanghong was used as the test material, and the material was obtained from the National Fruit Tree Germplasm Zuojia Mountain Grape Resource Garden of the Institute of Special Products, Chinese Academy of Agricultural Sciences, and the mountain grape seedlings were cultivated according to the method steps described in Example 1.

[0070] Wherein, in the cultivation process of Vitis vine seedlings in this embodiment, the conditions for the transition culture are: transfer the transition medium to the bottom of the culture rack, turn off the fluorescent lamp, so that the transition medium does not receive light, and store the transition medium at room temperature 25°C. , and the indoor humidity was controlled at 50% for transitional cultivation for 10 days.

[0071] The transition medium is 1 / 2 MS basic medium, in which 6-benzylaminopurine, naphthaleneacetic acid, agar, sucrose are dissolved, and activated carbon is added. In the transition med...

Abstract

The invention provides a grape tissue culture medium. In the culture medium of the present invention, the water potential of the culture medium is reduced by increasing the concentration of substances such as agar and sucrose in the medium, which to a certain extent reduces the pressure of the tissue culture of the grape. The occurrence of seedling vitrification, especially in the induction stage. At the same time, the addition of activated carbon in the medium can avoid the browning of tissue culture seedlings caused by the increase of sucrose concentration in the medium, thereby improving the success rate of Vitis vine tissue culture. Simultaneously, the present invention also provides a kind of Vitis vine tissue culture method, in the method of the present invention, by further adding transition culture step in the existing tissue culture seedling process, and using the culture medium described in the present invention as induction medium and proliferation culture Therefore, through the optimization of the culture process and the medium used, the vitrification phenomenon in the process of induction culture and proliferation culture of Vitis vine was effectively controlled.

Description

technical field [0001] The invention relates to the field of plant tissue culture, in particular to a vine tissue culture medium and a vine tissue culture method. Background technique [0002] Mountain grape (Vitis amurensis Rupr.) is native to Northeast China, North Korea, and the Far East of the former Soviet Union. Mountain grapes are also the main raw materials for the wine-making industry in Northeast my country. The wines produced are bright and transparent, and have unique flavors, so they are very popular among consumers. At the same time, Vitis vinifera is also the most cold-resistant species in the genus Vitis, and it also has strong resistance to white rot, powdery mildew, anthracnose and black bean disease. Therefore, it is an important germplasm resource for cold-resistant and stress-resistant grape breeding, and has high economic value. [0003] The Institute of Specialty Products of the Chinese Academy of Agricultural Sciences has established a national frui...
