Embodiment 1

[0039] 1) on the ultra-clean workbench, cut the young leaves of Sagittarius as explants, and sterilize the surface of the explants with 75% alcohol and 5% sodium hypochlorite solution;

[0040] 2) The explants after surface disinfection were cross-cut into 2mm squares along the vertical midrib direction, and the leaf backs of the explants were inoculated in the induction medium of culture bottles, and 10 plants of the explants were inoculated in each bottle. said explant;

[0041] 3) The explants inoculated in the culture bottle were first subjected to dark treatment for 3 days, and then cultured for 20 days under the conditions of light intensity of 800Lux, light time of 12h / d, and temperature of 20°C to obtain induced adventitious buds;

[0042] 4) Inoculate the induced adventitious buds into the rooting medium, and the number of inoculations in each bottle of rooting medium is 10, and the light intensity is 800Lux, the light time is 12h / d, and the temperature is 20°C. Take...

Abstract

The invention discloses a method for tissue culture and rapid propagation of Sagittarius, which comprises the following steps: 1) disinfection; 2) cutting the explant after surface disinfection into squares of 2 to 6 mm along the vertical midrib direction, and the explant The leaf back of body is inoculated in the induction medium of culture bottle downwards, and every bottle is inoculated 10 described explants; 3) the adventitious buds of induction; 4) the adventitious buds of described induction are inoculated in the rooting medium, It can take root after 60-70 days of culture. Through the in vitro culture of S. saxifolius, the tissue culture and rapid propagation system of S. The problems of scarcity of seeds, low germination rate and slow propagation speed are applicable to the industrialized seedling raising of Sagittarius; the propagation speed has been significantly improved, which has increased the amount of seedlings used for the rare Yi medicine Sagittarius, and expanded the production capacity of Sagittarius. The number of germplasm resources can be reduced at the same time, the operation is simple, and the economic benefit is high.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine planting, in particular to a method for tissue culture and rapid propagation of Sagittarius sativa. Background technique [0002] Anemones rivularis Buch.-ham.ex Dc, also known as Caoyumei, Jianfengqing, Jianfenglan, is a perennial herb medicinal plant of the family Ranunculaceae. , anti-cancer effects. Sagittarius often grows in mountains, grasslands, streamsides or other wetlands or forest edges in Yunnan at an altitude of 1750m to 3300m. Secondly, it is also distributed in Sichuan, Guizhou, southwestern Gansu, southeastern Qinghai, southwestern Hubei, western Guangxi, southern and eastern Tibet. However, with the change of environmental conditions, the wild Sagittarius is on the verge of extinction, resulting in a shortage of resources, and the supply exceeds demand. . [0003] Under natural conditions, the seed-setting rate of Sagittarius is very low, and the seed life ...
