Subgeneric and Specific Differences in the Chemical Composition of the Seed in the Genus Glycine

[摘要] The chemical composition of the seed of the genus Glycine was investigated on Glycine max (8 samples), G. gracilis (4 samples) and G. soja (7 samples) belonging to the subgenus Soja, and G. tabacina (3 samples) and G. tomentella (2 samples) belonging to the subgenus Glycine. On the chemical composition, characteristic differences between 2 subgenenus were observed, namely, the subgenus Soja was higher in protein and potassium content, and lower in carbohydrate and calcium content than the subgenus Glycine. In the subgenus Soja, the highest oil and potassium content and the lowest phosphorus and calcium content were observed in G. max, and the highest protein content and the lowest oil content were observed in G. soja. In the subgenus Glycine, however, the chemical composition, except calcium and magnesium was almost the same between G. tabacina and G. tomentella. Among the species, significant differenccs were observed in protein, oil, carbohydrate, potassium, and calcium content. Between chemical components, positive correlations were observed in the pairs of ash and potassium, phosphorus or magnesium content, potassium and phosphorus or magnesium content, and phosphorus and magnesium content. On the other hand, negative correlations were observed in the pairs of protein and carbohydrate content, oil and phosphorus content, and carbohydrate and potassium content.
