Last Updated: 2024/11/05, 1. Twenty thousand 3-year-old seedlings of Taxus mairei were introduced from Canada, which were mainly used in large-scale production of paclitaxel. The growth of Taxus in China is slow, the content of taxol is relatively low, and it is listed as a national first-class protected plant as a rare tree species. The taxol content in the branches and leaves of Taxus mairei is about 0.02%, and the content in the bark is 0.03%-0.04%, which is 2-3 times of the 60-year-old bark of Taxus mairei, and the growth rate is 3 times that of Taxus mairei. With unknown trunk
