Method for rapidly releasing dormancy of brucea javanica seeds

Abstract

The invention relates to a method for rapidly releasing dormancy of brucea javanica seeds, which comprises the following steps: 1)storing ripe brucea javanica fruits for 7-14 days at low temperature of 4 DEG C; 2)immersing brucea javanica fruits for 1-5 days in warm water at 20-30 DEG C, kneading by using 5wt%-20wt% of fine sand and removing pulp; 3)processing brucea javanica seeds by concentrated sulfuric acid with concentration of 98% for 30-90 seconds, and using running water for flushing until no sulfuric acid is residual; 4)processing brucea javanica seeds by using 100-300mg / L of gibberellin (GA3) aqueous solution for 2-48 hours; and 5) sprouting the processed brucea javanica seeds. The method has the advantages of shortening of seedling growing period and tidiness of seedling, and can be widely used for seedling, breeding and cultivating of medicinal material brucea javanica seeds.

Description

technical field [0001] The invention relates to the field of germination of medicinal plant seeds, in particular, the invention relates to a method for quickly releasing the dormancy of the seeds of Brucea javanica. Background technique [0002] Brucea javanica (L.) Merr.Rhusjavanica L. is the dried fruit of Brucea javanica (L.) Merr. Rhusjavanica L., which is the best-selling Chinese patent medicine such as Brucea javanica oil soft capsule, Brucea javanica oil oral emulsion, Brucea javanica oil emulsion injection, etc. raw material. In recent years, Chinese patent medicines with Brucea javanica as functional raw materials have remarkable curative effects, and the demand has grown rapidly, which has caused the price of raw materials of Brucea javanica to rise year after year. The supply of raw materials is seriously insufficient, and the shortage of goods is serious. The huge demand for Brucea javanica as a raw material for medicine has led to serious damage to wild resourc...

AI Technical Summary

Problems solved by technology

The huge demand for Brucea javanica as a raw material for medicine has led to serious damage to wild resources, and the collection of wild resources can no longer meet production needs. Standardized production is an effective way to solve the shortage of medicinal materials, and seedling breeding is an important part of standardized production. Brucea javanica fruit has a long ripening cycle, different degrees of seed maturity, plus the difficulty of separating the pulp from the seeds, the seeds are perishable, and the seed coat is hard, etc., resulting in a long breeding cycle for the seedlings of Brucea javanica and inconsistent emergence, which seriously affects the growth of Brucea javanica. Standardized cultivation

[0003] Through the retrieval of domestic and foreign literature and patents, a total of 1 literature was retrieved on the germination of Brucea javanica seeds and seedling propagation, Li Xianghong et al. Chinese Horticultural Abstracts, 2009 (1): 42-45.) briefly introduced the germination technology of Brucea javanica seeds, and the result is that: Brucea javanica seeds need to be placed for a period of time to pass through the dormant period, and then heated at 50~55°C Soak the seeds in water for 15-20 minutes, wash them for 2-3 times, then soak them in water for 12-24 hours, and place them in an environment of 33-35°C for germination. During the germination process, keep the humidity. After 7-10 days, the seeds will germinate one after another. 10% to 20% of the bud points can be sown, but the germination of Brucea javanica is irregular, and the emergence of seedlings lasts for a year
