| 摘 要： | 通过研究4个种源(塔河、松岭、黑河、带岭)兴安落叶松(Larix gmelinii Rupr.)、多年生枝针叶和当年生枝针叶氮浓度的季节动态和种源差异,结果表明:4种源兴安落叶松多年生枝针叶和当年生枝针叶氮浓度均在8月份达到最大值,7月份出现最小值;当年生枝叶氮浓度仅在生长季初期的6月和7月存在显著差异(P0.05),而多年生枝叶氮浓度在整个生长季内都无显著差异。

| Abstract: | Based on the 4 seed source （ Tahe, Songling , Heihe, Dailing） of Larix gmelinii Rupr and the difference for the needle leaf nitrogen between perennial branch and the current branch. The resuhs showed that the needle leaf nitrogen between perennial branch and the current branch get the highest value at August and the lowest value at July. The needle leaf nitrogen has significant difference （ P 〈 0. 05 ） between June and July. It has no significant difference in the whole process. |
