The focus of leaf development modeling in the last two decades has been on predicting commercial crop yields and identifying the constraints on them. The weakness of this approach: the implicit belief in the existence of a "global brain" deciding which parts of the plant are deficient and directing remedial action. Leaf Development and Canopy Growth presents an alternative view based on "local rules" - the simple results of metabolic processes within each cell. These rules and the interconnections between them provide the means for self-organization within the plant and emergent global...
