example 1

[0014] Example 1: 1. Choose a sturdy southern yew tree as the female parent tree.

[0015] 2. In mid-to-late October, the pericarp of the seeds of Taxus chinensis var. mairei turns dark red, and is harvested after being fully matured, and stored in a cool indoor place at a temperature of about 20°C.

[0016] 3. In late October, the harvested southern yew seeds will be soaked in water for 40 days to rot, and the pulp will be manually rubbed off, then the pulp and peel will be washed off with water and dried. Mix the moist silt with the southern yew seeds at a ratio of 10:1, and choose a cool room for storage, at a temperature of 8-15℃, and store until the beginning of April of the next year. Keep the silt moist at any time, and the humidity of the wet sand is about 30 %.

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

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 seed dormancy of the southern yew. Background technique [0002] Taxus chinensis var. mairei is a first-level 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. While the market demand is huge and the supply is in short supply, in order to protect the yew, an ancient endangered plant, countries around the world have enacted legislation to prohibit commercial collection and use of it. The Convention on International Trade in Endangered Species of Wild Fauna and Flora also included it. Appendix II requires strict regulation of its international trade to prevent excessive consumption of resources. This intensified the contradiction between supply and demand in the paclitaxel market, and resources became a bottle...
