摘　　要：收集新疆落叶松天然分布区 14个种源种子 ,在富蕴林区播种育苗和造林 ,对各种源多个性状进行测定分析。研究结果表明 :( 1)种源间生长物候和适应性无明显差异 ,选择最佳造林种源以生长性状为主。 ( 2 ) 2～ 5龄苗各年度间高生长量秩次相关紧密 ,种源间生长差异的遗传稳定性较好。 ( 3)主分量综合分析 ,该营林生态区重点发展奇台种源的新疆落叶松 ,辅以选择布尔津、阿尔泰。This paper studied the multi characteristics of Larix sibirica seeds from 14 provenance in Fuyun forest area. The results are as follows: (1) It is not remarkable for the phonological period and adaptability amony different provenance. Growth properties are the main factors in provenance selection. (2) The annual growth heights of 2~5 year old seedlings are closely related among 14 provenance. The genetic stability of the growth is good among the provenance. (3) Principal component analysis shows that the Qitai provenance is the best one, then and Buerjing, Aertai, Habahe and Qinghe provenance in this forest region.
