The Identification Standards and Methods of the Carbonized Soybean in Archaeological Excavations

Zhao Zhijun;Yang Jingang;  
The soybean remains found in archaeological sites are mainly charred beans. This article attempts to establish the identification criteria for domesticated soybean and wild soybean, through the observation of the morphological characteristics of the modern specimens of soybean, the experiments of carbonization of specimens of soybean, and the examination of charred soybeans unearthed from the archaeological sites. The identification criteria include the characteristics of seed coat and cotyledons, as well as the size of beans. The results suggest that in order to distinguish domesticated soybean from wild soybean, the changes of seed coat after carbonization are the most useful criteria, followed by the changes of cotyledons after carbonization. While the size of beans is not reliable criteria and has only a reference value.
