Our project is aimed at monitoring externally visible phenological changes of Scots pine at high latitudes in Finland during the growing season and linking these intra-annual changes with the internally proceeding cambium dynamics and the seasonal formation of water conducting cells, as well as trying to detect climatic driving forces behind these processes. Other features, such as wood density, lignification and ion content in the cambial zone are analysed for their potential in signalling climate effects. Based on these results, we will try to estimate changes of tree growth in boreal forests in view of the expected rise of temperature.

我们的项目旨在监测外部可见的物候变化苏格兰松在高纬度地区在芬兰的生长季节，并将这些年内的变化与内部进行形成层动态和水传导细胞的季节性形成联系起来，以及试图检测这些过程背后的气候驱动力。其他功能，如木材密度，木质化和离子含量在形成层区进行了分析，其潜在的信号气候效应。根据这些结果，我们将尝试估计树木生长的变化，在北方森林鉴于预期的温度上升。
