In this subproject, we will screen relevant poplar phenology traits important for biomass production (e.g. spring bud break, autumn bud set and leaf shedding) across various sites in the Nordic-Baltic region, These traits will then be related to climate data, frost damage and biomass production.
To meet these goals, we will develop a mathematical mechanistic model, describing poplar biomass growth as a function of climatic conditions and specific traits. The model will link leaf-level traits to biomass accumulation, by combining a mechanistic description of the leaf-level activity, including temperature acclimation, with a simple plant resource allocation model.
