Abstract

The invention discloses an in-vitro preservation method of corydalis thalictrifolia. The method comprises the following steps: performing tissue culture two-step seedling development on corydalis thalictrifolia, and inoculating test-tube seedlings with 4-6 leaves obtained by utilizing tissue culture two-step seedling development into a preservation medium for performing in-vitro preservation. The preservation medium refers to 1 / 2MS+PPP3331.0mg / l+0.3% of AC+ 4.5% of cane sugar+0.4 % of agar. The pH value of the medium is 5.8, the temperature is 21+ / -1 DEG C, the illumination intensity is 1400-1600lx, and the illumination time is 8-10 hours per day. According to the method disclosed by the invention, lots of high quality seedlings of corydalis thalictrifolia can be provided in a short time, the steps of preparing the medium and spinning the bottle are reduced, and lots of manpower and material resources are saved; and therefore, the method is simple and feasible, the production cost is reduced, and the purpose of preservation and large-scale seedling growing of corydalis thalictrifolia germplasm resources can be effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of biological tissue culture, and in particular relates to an in vitro preservation method of Litectin chinensis. Background technique [0002] Corydalissaxicola Bunting (Corydalissaxicola Bunting) is a plant of the Papaveraceae family, a perennial herb, distributed in Guangxi, Guangdong, Fujian, Hunan and other provinces in my country. The whole herb is used as medicine, and it is a famous Zhuang Yao medicine variety. The whole herb contains active ingredients such as dehydrocarvitin (petidine); it has significant antibacterial, anti-inflammatory, analgesic and strong stabilizing effects, and it has been observed to inhibit tumor cells. Function; Indications for treating sores, furuncles, swollen toxins, hepatitis, cirrhosis, and liver cancer. Due to the poor habitat conditions, its natural reproduction rate is very low, and its seeds are small, so it is difficult to reproduce, the population development i...
