对9个种源兴安落叶松种子的发芽特性进行研究的结果表明，不同种源间的发芽率、发芽势、发芽指数及平均发芽速度显著不同，显著水平均达到0．0001。利用发芽率、发芽势和发芽指数对不同种源的种子进行聚类分析，利用类平均法筛选的兴安落叶松最佳种源，种子为黑龙江省呼中、内蒙古金河和黑龙江省阿木尔；利用最短距离法筛选的兴安落叶松最佳种源种子为呼中和金河。

The germination characteristics of Larix gmelinii seeds from nine sources was studied , results showed that germination rate , germination vigor , germination index , and germination speed of Larix gmelinii seeds from different sources were significantly different , and the significant levels were all reached to 0.0001.Three indexes include germination rate , germination vigor , germination index , and germination speed were used to conduct cluster analysis . Huzhong of Heilongjiang , Jinhe of Inner Mongolia and Amuer of Heilongjiang were selected as the best seed sources by group average method cluster analysis .Meanwhile Huzhong of Heilongjiang and Jinhe of Inner Mongolia were selected as the best seed sources by shortest distance method cluster analysis .
