Morphological characteristics of silica bodies from motor cells of rice from Luojiajiao site and their implication on rice evolution
Analysis of silica bodies was carried out for 15 earthenware fragments unearthed from 4 cultural layers of the Luojiajiao site, Zhejiang. As a result, the silica bodies of rice were detected in 5 carthenware fragments from the 2<sup>nd</sup>, 3<sup>rd</sup> and 4<sup>th...

| Summary: | Analysis of silica bodies was carried out for 15 earthenware fragments unearthed from 4 cultural layers of the Luojiajiao site, Zhejiang. As a result, the silica bodies of rice were detected in 5 carthenware fragments from the 2<sup>nd</sup>, 3<sup>rd</sup> and 4<sup>th</sup> cultural layers. Further, analyzing of morphological characteristics showed that the silica bodies were small comparatively, with short vertical, horizontal lengths and big shape coefficients, small discrimination scales based on the shape. The results implied that they were similar to the silica bodies driving from indica more than from japonica. Also, it appeared that the distributions of the silica bodies were of multi-peaks. From the results, it was supposed that rice cultivated in the Luojiajiao site or around it. 7000 years ago were varied populations, in which hsien (indica) was main and king (japonica) was contained too. |
