【 摘 要 】

It is possible to analyze the chemical constituents or physical properties of each rice grain, and attempts are being made to clarify the relationship between the analytical results and position of the grain on the panicle. The objective of this study is to develop a computer program for schematic presentation of the branching structure of rice panicle, and for illustrating the information of each grain corresponding to their position on the panicle. The branching structure of panicle was described in list-format in order to deal with their diverse structures. A programming language Prolog, with unique characteristics such as pattern matching and unification, was used to develop the drawing program by fully utilizing its recursive call function. For the effective utilization of the analytical results already recorded in table-format, another Prolog program was developed to convert them into the data described in list-format. Besides illustrating the qualitative information, such as existence or degeneration of spikelet, another function to illustrate the grains in specific colors, according to their quantitative information, such as fresh weight, was added to the drawing program. Although the drawn schematic illustration was not accurate in terms of the length of rachis and shape of grain, the relative positions of rachises and grains were precisely expressed, and it was concluded that this illustration was helpful in understanding the relationship between the qualitative or quantitative properties of grains and their positions on the panicle intuitively. Application of this drawing program to the panicle of Genus Oryza, which has similar branching structure, or the tillering system of rice, is thought to be possible.
