Abstract
Superscope (recently developed by Nippon Denshi Co., Ltd.) was used in this study. Starch granules from adzuki bean (Phaseolus chrysanthos) and smooth bean (Pisum sativum var. arvense) were molded into replica by use of Bioden R. F. A. (acetylcellulose film of Ôken Shoji Co.), Bioden was softened by the vapor of methyl acetate, and the sample granules were molded by their own weight. This method or the so-called self-molding method was presumed to cause less physical deformation on the samples than the method of methacrylate resin coating reported formerly (Part X, 1968). Satisfactory results were obtained at relatively lower magnifications of 2000-5000.
