内容記述 |
We quantitatively evaluated the shape and size variations of stones of Japanese and Chinese cultivars of Japanese apricot (Prunus mume Sieb. et Zucc.). We also examined ways of identifying cultivars based on quantitative evaluations of the stone shape and size. Stones were photographed from two directions, i .e lateral side and front side, and the contours of the stones were extracted by image analysis and delineated by elliptic Fourier descriptors. Principal component analysis of the descriptors was conducted, and the scores of the components were used as shape characteristics. Regarding size, we measured height, width and thickness of the stones by digital caliper, and the products and ratios of these measurements were used as size characteristics. Using the Ward's cluster analysis based on these characteristics, 64 samples, which consisted of Japanese and Chinese cultivars/selections, were classified into seven groups. Four samples from the two Chinese cultivars were all classified into one group (A), and the 60 Japanese cultivars/selections were classified into the remaining groups (B-G). Using support vector machines, a model was constructed to classify a stone into one of the seven groups based on the shape and size characteristics. The model was applied to stones extracted from 50 ume-boshi (pickled mume) products sold on the Japanese market. As a result, 31 products labeled as made from Chinese cultivars were all classified into group A. Over 60% of the 19 products labeled as made from fruit of cultivars of Japanese origin were assigned to one of the remaining groups (B-G). The results suggested that the method presented here may allow us to distinguish stones of Chinese cultivars from Japanese ones and to detect mislabeling of the country of origin. |
