Light Interception by an Isolated Plant A Simple Model

Abstract

A simple model for light interception by an isolated plant is proposed. The model assumes that the leaves are uniformly distributed over a region of space bounded by an ellipsoid and a plane, and that light traversing this region is attenuated according to Beer's law. It is shown how the model can be extended to examine a closed row of plants, or a closed array of plants. Simulated light profiles have been calculated for single plants with different shapes, and an isolated row of plants, under uniform and standard overcast skies.
