摘　　要：[目的]选育适宜高寒地区气候条件下的绿化用黄杨品系。[方法]对沈阳、丹东、大连3个种源地的黄杨进行播种试验,调查幼苗当年高、当年地径,统计千粒重、发芽率。[结果]3个种源朝鲜黄杨种子在千粒重、发芽率上存在不同程度差异,千粒重越大,发芽率越高;3个种源朝鲜黄杨幼苗当年高和当年地径差异显著(P<0.05)。[结论]从当年高和当年地径来看,沈阳种源最好,丹东次之,大连最差。Objective] To select suitable varieties of Buxus microphylla var.koreana.[Method] Sowing test on B.microphylla was carried out in three provenances of Shenyang, Dandong and Dalian.Seedling height, ground diameter, 1 000-grain weight and germination rate were investi-gated.[Result] Seeds from three provenances showed certain differences in 1000-grain weight and germination rate.Greater 1 000-grain weight led to higher germination rate.B.microphylla seeds from three provenances had significant differences in plant height and ground diameter （P ＆lt;0.05）.[Conclusion] According to the plant height and ground diameter, provenance in Shenyang is the optimal, followed with Dandong.And Dalian is the worst.
