Data for "Age effect on tree structure and biomass allocation in Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies [L.] Karst.)"

VAPU dataset for tree biomass was collected from southern Finland in 1988-1990 by the Finnish Forest Research Institute (Metla, now Natural Resources Institute Finland, Luke) (VAPU data set). Those sample trees (162 Scots pine and 163 Norway spruce) are originated from the whole VAPU data set. The sheet 'Pine' and 'Spruce' data have been matched between 'sample branch measurements' and the 'biomass' information (by cluster X, Y, and plot, tree number). Biomass estimation for foliage and branches has been described here: https://doi.org/10.1016/j.ecolmodel.2004.04.024 and https://doi.org/10.1093/treephys/25.7.803<br>VAPU林木生物量数据集由芬兰森林研究所（Metla，现为芬兰自然资源研究所Luke）于1988—1990年在芬兰南部采集完成，即VAPU数据集。本次选取的162株欧洲赤松与163株挪威云杉均取自完整的VAPU数据集。数据表中「Pine」与「Spruce」工作表已通过聚类X、Y、样地信息及林木序号，完成「样枝测量数据」与「生物量信息」的匹配关联。叶部与枝干生物量的估算方法已在以下两篇文献中详述：https://doi.org/10.1016/j.ecolmodel.2004.04.024 与 https://doi.org/10.1093/treephys/25.7.803。
