ABSTRACT IN the creation and validation of plant simulation models, it is desirable to obtain experimental data of various growth response parameters of the plant. Typically, this has meant harvesting a large number of plants and destructively determining the characteristics of an '^average'' plant. Growth chamber studies with a limited population of plants do not allow destructive plant growth measurements. Futhermore, plant competition and special field studies of crop growth mechanisms are best accomplished by non-destructive analyses of individual plants. Electronic image analysis was evaluated as a method for non-destructive measure of in-situ leaf area, stem diameter, and leaf and petiole angles. These measurements were obtained using a lowcost electronic image analysis system with a personal computer.
