摘　　要：[目的]对不同种源朝鲜黄杨进行引种调查研究。[方法]采用随机踏查的方法对沈阳东陵区、丹东五龙背、大连旅顺口3个地方朝鲜黄杨的生长情况进行调查,对朝鲜黄杨的引种选择指标及3个种源间的差异进行分析。[结果]地径年生长量、枝径年生长量、株高年生长量、枝数、枝下高、冠型这6个调查指标可以作为引种选择指标,6个调查指标可以整合成2个主成分,分别代表生长特性和树形特性;在0.05显著性水平下,3个种源朝鲜黄杨在地径年生长量、枝径年生长量、株高年生长量、枝下高4个指标上差异显著;大连旅顺口种源和丹东五龙背、沈阳东陵区种源朝鲜黄杨在枝数指标上差异显著,丹东五龙背、沈阳东陵区种源差异不显著;3个不同种源朝鲜黄杨在黄杨冠型上差异不显著。[结论]该研究可为朝鲜黄杨引种指标的选择和分析提供参考。Objective] The aim was to investigate introduction of B.microphylla var.koreana from different provenance.[Method] The growth situation of B.microphylla var.koreana from Shenyang Dongling District, Dandong Wulongbei, Dalian Lushunkou was investigated by random surveying.[Result] Ground diameter, branch diameter and plant height annual production volume, branch number, shoot height and crown type can be used as introduction selective indicators, they were divided into two principal components, respectively representing growth features and tree shape features; B.microphylla var.koreana from three provenance had significant difference in four indicators of ground diameter, branch di-ameter, plant height annual production volume and shoot height at 0.05 level; B.microphylla var.koreana from Dandong Wulongbei and Sheny-ang Dongling District had no significant difference; B.microphylla var.koreana from three provenance had no significant difference in crown type.[Conclusion] The study can provide reference for selection and analysis of introduction indicators of B.microphylla var.koreana .
