Problems solved by technology

[0003] The reproduction method of wild Scrophulariaceae is to use seeds for sexual reproduction, while Yaonong adopts asexual reproduction method for cultivating Scrophulariaceae in order to preserve high-quality varieties, increase yield and shorten the growth cycle. Seriously, the output and quality have dropped significantly

Embodiment 1

[0025] 1. Strain screening

[0026] During the growth period of Scrophulariaceae Scrophulariae, the above-ground chip selection was carried out in Qiaocheng District, Bozhou City, and the underground traits were screened on the basis of the chip selection during the harvest period. garden.

[0027] Through the identification of variety characteristics, it is consistent with the characters of Scrophulariaceae Scrophulariaceae in Flora of China.

[0028] Perennial herb, plant height 140-160cm. Root hypertrophy, nearly cylindrical or spindle-shaped, with 3 to 6 branched roots, 3 to 4 cm thick, grayish-brown skin, many longitudinal wrinkles, lenticels, and most buds wrapped by white scales at the top. Stems erect, square, smooth or glandular pilose. The leaves are opposite, the leaves are ovate or ovate-elliptic, the apex is acuminate, the base is round or nearly truncate, the edge is serrated, and the tooth margin is recurved; the back of the leaf has sparse and scattered fine...

Embodiment 2

[0053] A method for breeding Scrophulariaceae, comprising the following steps:

[0054] a. Strain screening

[0055] During the harvest period of Scrophulariae scrophulariae, the plants with vigorous growth in the field, no pests and diseases, many roots, and hypertrophy of the root system are selected, and planted in the resource garden;

[0056] b. Material processing and stem tip stripping

[0057] (1) Pretreatment and disinfection

[0058] During the harvest period of Scrophulariaceae, take the buds wrapped in white scales at the top of the root, wash with tap water to remove the dirt and dust on the surface, and peel off the outer scales of the buds layer by layer to 1cm 3 , soak in 70% alcohol solution under aseptic conditions for 10 seconds, then soak in 0.1% mercuric solution for 10 minutes, and soak in sterile water for 6 times;

[0059] (2) Stem tip stripping

[0060] Under the dissecting microscope, the shoot tips of the terminal buds treated in step (1) were ca...

Abstract

The invention discloses a scrophularia ningpoensis hemsl breeding method. The scrophularia ningpoensis hemsl breeding method comprises the following steps: a, screening strains; b, treating materials; c, establishing a clone; and d, hardening and transplanting seedlings. According to the scrophularia ningpoensis hemsl breeding method, detoxified germchits have the excellent performance in a field; plants are strong and have the consistent growth vigor; leaves are green, plump and wide; and the quality of a product is extremely improved. Breeder's seeds have no plant diseases and insect pests in the field, and the occurrence possibility of the plant diseases and insect pests of foundation seeds and production seeds is extremely small; and the yields are increased by 166.6% and 152.8% respectively when being compared with that of conventional seedlings.

Description

technical field [0001] The invention relates to the field of tissue culture, in particular to a method for breeding Scrophulariaceae. Background technique [0002] Scrophulariaceae is the dried root of Scrophulariaceae Scrophulariae (Scrophularianingpoensis Hemsl.), which was first recorded in "Shen Nong's Materia Medica". Spots, bone steaming, labor cough, red eyes, sore throat, diphtheria, carbuncle and sores are endemic species in my country. At present, they are only naturally distributed in China. They are cultivated in most parts of the country. They are mainly produced in Zhejiang, Anhui, Hubei, Guizhou and other places. It is a commonly used bulk medicinal material. As a raw material of Chinese patent medicine, it can produce dozens of Chinese patent medicines such as Tianwang Buxin Pill, Tianma Pill, Mailuoning, Qingyanhou Mixture, etc. Now it is also used in the production of cosmetics as a plant lubricant, antifreeze, anti Wrinkle cream etc. [0003] The reproduc...
