Last Updated: 2024/11/05, The method of seed reproduction and seed coat damage of Taxus chinensis is as follows: the seed has a long post-maturity period and dormancy characteristics, and can germinate only after two winters and one summer under natural conditions, that is, it can be frozen outdoors in winter, exposed to high temperature and rain in summer, sown in autumn of the following year, if sown in spring, it can still be frozen outdoors after winter, and sown in a greenhouse after germination from late March to early April. It can germinate more than 20 days after sowing. If the seeds can be repeatedly rubbed with coarse sand and soles on rough cement ground, the inconspicuous tough seed coat will be worn out and the hard seed shell will be thinned (

If the seed can be repeatedly rubbed with coarse sand and sole on rough cement ground, the inconspicuous tough seed coat can be worn, and the hard seed shell can be worn thin (do not wear the seed kernel), so that the seed can be easily permeable to water and air, and the seed germination can be faster.
