Abstract

The seed of Taxus chinensis ( Pilger) Rehd . has a long postmature duration only with the germination of 29.5 %~
37 .5 % after 4070 d when its dormancy is relieved.The low limit of mean temperature for shooting is 15
, the mean height of 1-year-old and 2-years-old seedlings is 8 .12 cm and 16.10 cm respectively, mean basal diameter of 2-years-old seedling is 0.19 cm.Soft-wood + 50 mg/ kg ABT + sandy bed in spring and hard-wood +100 mg/ kg NAA +sandy bed in autumn are the best treatments for cutting propagation, the survival rate of afforestation may reach 100 %.Their mean height is 70.48 cm, basal diameter is 1 .01 cm, and branch is 40 50 cm in second year for plantation.
