| 摘 要： | 通过26年生长白落叶松种源试验的调查分析表明：长白落叶松在加格达奇试验区其性状及变异是稳定的，可以进行早期选择。各种源间的胸径、树高、材积生长都存在较显著差异。9个种源的生长性状可划分为5个种源区，即：Ⅰ、鸡西种源区；Ⅱ、小北湖种源区（包括小北湖、大海林）；Ⅲ、白刀山种源区（包括白刀山、穆棱）；Ⅳ、露水河种源区（包括露水河、白河）；Ⅴ、天桥岭种源区（包括天桥岭、和龙）。种源选择的效果较为明显。低海拔、低等效纬度的鸡西种源为加格达奇试验点的最佳种源，大海林、小北湖种源也是可选种源。

| Abstract: | Provenance tests of 26-year-old Larix olgensis were conducted.The result shows that characters and variation of Larix olgensis in Jiagedaqi test area are stable and it can be early selected.There are significant differences in DBH,tree height,and volume growth among different provenances.Nine provenances can be divided into 5 provenance region:Ⅰ.Jixi provenance region;Ⅱ.Xiaobeihu provenance region(including Xiaobeihu,Dahailin provenance);Ⅲ.Baidaoshan provenance region(including Baidaoshan,Muling provenance);Ⅳ.Lushuihe provenance region(Lushuihe,Baihe provenance);Ⅴ.Tianqiaoling provenance region(including Tianqiaoling,Helong provenance).The effect of provenance selection is significant.The optimal provenance in Jiagedaqi test area is Jixi provenance whose altitude and equivalent latitude are low.Dahailin,Xiaobeihu provenance are also provenance to be selected. |
