Example Embodiment
[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, and then washed with water to remove the pulp and peel, 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 out the mud and sand, wash the southern yew seeds with clean water, and soak them in a 500ppm gibberellin solution at 40℃ for 2 hours, and choose sunny days for sowing.
