Abstract

Tree-ring anatomical structure is the key to understanding of adaptive specifics of xylem of various species to climate change. This is especially significant in the permafrost zone due to likely permafrost degradation. We compared anatomic features of annual rings of Dahurian larch (Larix gmelinii (Rupr.) Rupr., Larix cajanderi Mayr.), Scots pine (Pinus sylvestris L.) and Siberian spruce (Picea obovata Ledeb.) growing in the permafrost zone in Central Siberia for 1960–2011. Climatic factors affecting tree radial growth and anatomic features of tracheids of coniferous species were revealed.

西伯利亚中部多年冻土区落叶松，松树和云杉年轮年轮解剖特征的长期变化

摘要

树环的解剖结构是理解各种物种木质部适应气候变化的关键。由于多年冻土可能退化，这在多年冻土区尤为重要。我们比较了在中部多年冻土带中生长的Dahurian落叶松（Larix gmelinii（Rupr。）Rupr。，Larix cajanderi Mayr。），苏格兰松树（Pinus sylvestris L.）和西伯利亚云杉（Picea obovata Ledeb。）的年轮的解剖特征。 1960年至2011年的西伯利亚。揭示了影响针叶树种径向生长和气管解剖特征的气候因素。
