摘要
Based on the main characteristics of growth, phenology and resistance at both seedling stage (one year old) and sampling stage (seven years old) of Dahurian larch (Larix gmelinii (Rupr.) Rupr.) from seventeen provenances in China ranging from 47 ° 10' to 52 ° 25' N and 119 ° 57' to 130 ° 25' E, the rules and patterns of infraspecific geographic variation have been studied by using variance analysis, correlation analysis, partial correlation analysis and regression analysis. The best provenance for local site and its neighborhood was selected according to the growth characteristics of seven years provenance test on Liangshui Experimental Forest Farm of Northeast Forestry University.
