How much do radiative transfer models influence red:far-red simulation and subsequent modelling of plant photomorphogenesis? Open
Red:far-red ratio (R:FR) plays an important role in the architectural dynamics of vegetation. The integration of its effects into the crop model and/or into modelling work on plant dynamics over years requires new methods for describing R:…

LightCue: An Innovative Far-Red Light Emitter for Locally Modifying the Spectral Cue in Outdoor Conditions with Global Consequences on Plant Architecture Open
Plasticity of plant architecture is a promising lever to increase crop resilience to biotic and abiotic damage. Among the main drivers of its regulation are the spectral signals which occur via photomorphogenesis processes. In particular, …

Investigation of complex canopies with a functional–structural plant model as exemplified by leaf inclination effect on the functioning of pure and mixed stands of wheat during grain filling Open
The present work demonstrates that FSPMs provide a framework allowing the analysis of complex canopies such as studying the impact of particular plant traits, which would hardly be feasible experimentally. The present FSPM can help in inte…
