Temporal decoupling between photosynthetic carbon assimilation and wood formation across species and stand levels in a mixed broadleaf–Korean pine forest: implications for source-sink dynamics

This dataset provides daily relative photosynthetic rate and radial growth rate during the growing seasons of 2020–2024 for 12 dominant tree species in a mixed broadleaf–Korean pine forest in Northeast China: Pinus koraiensis, Tilia amurensis, Quercus mongolica, Fraxinus mandshurica, Acer mono, Ulmus japonica, Tilia mandshurica, Acer triflorum, Betula platyphylla, Acer mandshuricum, Phellodendron amurense, and Juglans mandshurica. The dataset was generated to investigate temporal lags between photosynthetic carbon assimilation and wood formation across species and years.
