 note = {A method was developed for the simple evaluation of tree canopies, and the relationship between leaf canopy density and chemical adhesive properties in apple trees was analyzed. This simple tree canopy evaluation method uses a leaf canopy density rating value. This value is measured with the use of a sheet of plywood (length 90 cm × width 180 cm) on which twenty-eight red circles (diameter 20 cm, four circles × seven lines) are drawn. The rating board is across a farm road from an evaluator, who then gives a numerical value to the extent of each red circle that can be seen though the tree canopy. Tree growth factors such as total leaf area per tree, total leaf area per planting area, relative luminous intensity under the tree canopy, total shoot length, and trunk girth were correlated with the leaf canopy rating value and chemical adhesive property of apple trees. The leaf canopy rating value was correlated with the chemical adhesive property. It is thought that with this simple tree canopy evaluation method the chemical adhesive property in an apple orchard can be measured in a short time. It is also thought that a new tree form training system with little drift can be developed with the use of this simple tree canopy evaluation method.},
