 This model produces a virtual plant canopy, initially consisting of 16 plants (four rows of four plants each). When you run the model, you will get the 3D visual output and also some curves (in the chart "MODEL OUTPUT") indicating the dynamics of several yield-related state variables: light absorbed by lower and upper leaves, light absorbed by soil, number of shed leaves, number of flowers and fruits, and the assimilates produced by lower and upper leaves (where ranks 1 - 4 are lower leaves, and ranks 5 - 9 are upper leaves). At this stage you are not supposed to understand all the workings of the model, the objective of this exercice is for you to play the grower and to change a limited number of agronomic and genetic parameters (planting density, plant architecture).  This model produces a virtual plant canopy, initially consisting of 16 plants (four rows of four plants each).
