摘要
以6处不同种源的南方红豆杉种子为研究对象，对种子千粒重、优良度、生活力、发芽率和发芽势进行比较分析的结果表明：不同种源的南方红豆杉种子千粒重范围为86．0—90．25g、优良度为85．0％-90．0％、有生活力的平均值为80．2％；发芽率的范围为64．6％-79．4％、发芽势的平均天数为15．17天；综合分析可知，九江市和桑植县的发芽特性最好，采用40％温水浸种20min，0．5g／kg赤霉素溶液浸种24h后，翌春播种后发芽率最高，为89．33％。
Take six different provenances seeds as the research object, thousand kernel weight, excellent degree, viability, germination rate and germination potential were analyzed. The results showed that different provenances of Taxus chinensis var. mairei weight of the seed ranges from 86. 0 - 90. 25g, excellent degree of 85.0% - 90. 0% , viability average of 80. 2%, the germination rate being in the range of 64. 6% -79.4%, germination potential average of 15. 17 d. The germination characteristics were the best in Jiujiang City and Sangzhi, using 40 ~C warm water soaking them for 20min, and 0. 5g/kg gibberellin solution soaking for 24h, sowing after the next spring resulting in the highest germination rate（89. 33% ）.
