example 1

[0014] Example 1: 1. Select a robust southern yew tree as the female parent tree.

[0015] 2. In the middle and late October, the peels of the seeds of Taxus chinensis turn dark red. They are harvested after they are fully mature and stored in a cool place indoors at a temperature of about 20°C.

[0016] 3. In late October, soak the harvested yew seeds in water for 40 days to rot the pulp, rub the pulp manually, wash the pulp and peel with water, and dry it in the air. Mix the wet sand with the seeds of Taxus chinensis at a ratio of 10:1, and store in a cool room at a temperature of 8-15°C until early April of the next year. Keep the sand moist at any time, and the humidity of the wet sand is about 30 %.

[0017] 4. In April of the next year, sieve out the mud and sand, wash the seeds of Taxus chinensis with clean water, soak them in 500ppm gibberellin aqueous solution at 40°C for 2 hours, and choose sunny days for sowing.

[0018] 5. Choose sandy loam soil with gentle slope...

Abstract

The invention relates to a method for breaking south Chinese yew seed dormancy. The method is characterized in that south Chinese yew seeds are processed by changing temperature and comprises the following steps of: a, immersion; b, storage; and c, sowing. The invention aims to solve the problems of long cultivation period, high cost and great technical difficulty for south Chinese yew introduction, and provides a simply-operated method for breaking the south Chinese yew seed dormancy at low cost. According to the invention, by the adoption of the method for breaking the south Chinese yew seed dormancy, emergence rate during the sowing year can reach 30%, and seedlings can emerge by 50% during the next year. Therefore, by the adoption of the method, seedling growing efficiency is raised.

Description

technical field [0001] The invention relates to a method for breaking the dormancy of southern yew seeds. Background technique [0002] Southern yew is a first-class protected wild plant in my country, and it is also a very important woody medicinal plant. It contains paclitaxel, one of the most effective anticancer drugs in recent years. According to statistics, the global annual demand for paclitaxel is 3000kg. At the same time that the market demand is huge and the supply is seriously in short supply, in order to protect the ancient and endangered plant yew, countries around the world have legislated to prohibit its commercial collection and utilization. It is also listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Appendix II requires strict regulation of its international trade to prevent excessive consumption of resources. As a result, the contradiction between supply and demand in the paclitaxel market has been exacerbated...
