Phenotypic traits, climate and biomass production
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.
