Model description

The dynamic virtual plant model L-Cucumber predicts growth and development of greenhouse grown cucumber plants under various light conditions and canopy architectures. Production of dry matter and growth of the shoot are dependent on the local light conditions of each individual leaf within the canopy, which are provided by acoupled light model. Using the L-System formalism, this FSPM combine a model for architectural development, a biochemical model of photosynthesis and a model for assimilate partitioning, the last including a fruit growth model based on a size-related potential growth rate. Starting from a distribution proportional to the size-related potential growth rate, the model was extended by including abortion and dominance. Abortion was related to source strength and dominance to sink strength.
