摘要
对红皮云杉（ＰｉｃｅａＫｏｒａｉｅｎｓｉｓＮａｋａｉ）第一次种源试验的３个代表试验林，８个种源１５年生子代生长性状的调查分析表明：红皮云杉天然分布区内存在着遗传变异；影响种源生长性状变异的主要地理因子为纬度和海拔；对３个试验林种源生长性状的遗传稳定性分析表明：高产稳产型种源仍然是柴河、天桥岭。
The results from the study on growth characteristics of eight provenances in 15 years old,three representative provenance trials of Picea koraiensis show that there are significant genetic variations within the natural distribution area of Picea koraiensis.The latitude and altitude are the main factors that affect the provenance growth characteristics. In addition,the growth stability of growth characteristics from three representative provenance trials is also studied. It indicated that Chaihe, Tianqiaoling, Dafeng and Wuyiling, as provenances with high yield and genetic stability, should be applied to the forestry production of Picea koraiensis in the future.
