Problems solved by technology

In the study of seed germination characteristics, although it has been found that gibberellin treatment can increase the germination rate of Begonia chinensis seeds, the effect is not good, and the germination rate is only 28%, which cannot effectively break the dormancy of Begonia chinensis seeds and solve the problem of artificial breeding

Embodiment 1

[0027] Collect the ripe yellow crabapple fruits from September to October, remove the shell after natural drying, remove impurities by winnowing, and select the clean seeds. Soak the seeds with a sodium hypochlorite solution with a mass concentration of 1% for 15 minutes for disinfection, rinse them with clean water, and dry the water on the surface of the seeds. Soak the sterilized seeds in 0.1 mM gibberellin GA 3 After 24 hours in the solution, the seeds were taken out, rinsed with clean water, placed on a glass petri dish with two layers of wet filter paper, sealed with plastic parafilm, and stored at 4°C for 3 weeks at low temperature. During the process, water was added to the Petri dish every 4 days to keep the filter paper moist. The filter paper and petri dishes used were sterilized by high temperature and high pressure at 120°C for 20 minutes before use. After wet storage, the petri dishes were taken out and placed in an incubator at 15°C with a light-dark cycle of ...

[0029] Collect the ripe yellow crabapple fruits from September to October, remove the shell after natural drying, remove impurities by winnowing, and select the clean seeds. Soak the seeds with a sodium hypochlorite solution with a mass concentration of 1% for 20 minutes, rinse them with clean water, and dry the water on the surface of the seeds. Soak the sterilized seeds in 0.1 mM GA 3 After 24 hours in the solution, the seeds were taken out, rinsed with clean water, placed on a glass petri dish with two layers of wet filter paper, sealed with a parafilm, and stored at 2°C for 3 weeks at low temperature. The wet storage process Water was added to the Petri dish every 3 days to keep the filter paper moist. The filter paper and petri dishes used were sterilized by high temperature and high pressure at 120°C for 20 minutes before use. After wet storage, the petri dishes were taken out and placed in an incubator at 15°C with a light-dark cycle of 12h / 12h for 28 days to accelera...

Embodiment 3

[0031] Collect the ripe yellow crabapple fruits from September to October, remove the shell after natural drying, remove impurities by winnowing, and select the clean seeds. Soak the seeds with a sodium hypochlorite solution with a mass concentration of 1% for 18 minutes, rinse them with clean water, and dry the moisture on the surface of the seeds. Soak the sterilized seeds in 0.2mM GA 3 After 24 hours in the solution, the seeds were taken out, rinsed with clean water, placed on a glass petri dish with two layers of wet filter paper, sealed with a parafilm, and stored at 4°C for 4 weeks at low temperature. The wet storage process Water was added to the Petri dish every 4 days to keep the filter paper moist. The filter paper and petri dishes used were sterilized by high temperature and high pressure at 120°C for 30 minutes before use. After wet storage, the petri dishes were taken out and placed in an incubator at 15°C with a light-dark cycle of 12h / 12h for 28 days to accele...

Abstract

The invention discloses a method for increasing the germination rate of Hypericum ascyron seeds. The method comprises the following steps: preparing mature Hypericum ascyron fruits, naturally drying in the shade, removing shells, and removing impurities by virtue of an air blast method, so as to pick out pure seeds; soaking the seeds in a 1% sodium hypochlorite solution for 15-20 minutes, flushing the seeds with clean water, and airing the surface moisture of the seeds; soaking the aired seeds in a 0.1mM-0.3mM gibberellins solution for 20-24 hours, taking out the seeds, flushing the seeds with clean water, and carrying out wet preservation on the seeds at 2-5 DEG C for 3-4 weeks; and after the wet preservation, carrying out germination accelerating on the seeds in an incubator, wherein the temperature is 15 DEG C, the light-dark period is that 12-hour illumination and 12-hour dark are alternate, and the culturing time is 25-30 days. By virtue of the method, the germination rate of the Hypericum ascyron seeds can be substantially increased, the artificial breeding difficulty is reduced, and the large-scale planting of Hypericum ascyron is realized.

Description

technical field [0001] The invention relates to the field of plant cultivation. More specifically, the present invention relates to a method for improving the germination rate of Begonia chinense seeds. Background technique [0002] Yellow Begonia (Hypericum ascyron L.) is a perennial herbaceous plant of the genus Hypericum in the Garciniaceae family. It grows in hillside forests, forest margins, bushes, grasses or meadows, beside streams and river bank wetlands. Huang Haitang is one of the commonly used Chinese medicinal materials in my country. The aboveground part is used for medicine. It has the functions of calming the liver, stopping bleeding, detoxification, reducing swelling, anti-inflammatory and analgesic. It is mainly used for vomiting blood, uterine bleeding, traumatic bleeding, sores, boils, Rheumatism, dysentery, and irregular menstruation. In addition, the yellow crabapple has many and large flowers, and its color is gorgeous, so it has a very high applicatio...
