Last Updated: 2024/11/24, The method of seed propagation and variable temperature treatment of Taxus mairei is as follows: Taxus seeds have the habit of double dormancy of radicle and Hypocotyl, and the radicle needs to go through the stage of high temperature above 25 degrees Celsius for one month to break dormancy. Hypocotyl needs to be at minus 3 degrees Celsius to minus 20 degrees Celsius for about one month. In order to accelerate seed germination early, as long as the seeds with damaged seed coat are mixed with wet sand and frozen in an environment below minus 3 degrees Celsius for 25 to 40 days, the Hypocotyl dormancy can be released after sowing in late winter or early spring.

In order to accelerate seed germination early, as long as Taxus chinensis seeds with damaged seed coat are mixed with wet sand and frozen in an environment below minus 3 degrees Celsius for 25 to 40 days, their Hypocotyl dormancy can be released. After sowing in late winter or early spring, radicle dormancy can be broken after 2 months or so when the temperature is above 25 degrees Celsius, and the seeds can sprout.
