【摘要】：用性状差异显著性测定、欧氏距离比较、粒型判别函数等方法,对云南保山昌宁达丙营盘山新石器遗址出土的145粒完整炭化稻米,经过复原为新鲜稻谷后,通过综合分析认为:保山昌宁营盘山古稻属于倾粳稻类型的栽培古稻群。在判别函数和距离测定数据指标上都属于粳稻类型。与参照系的各个性状差异极显著,包括与粳稻亦然;表明粒型与现代粳稻亦有不相同之特点。其粒型短而厚重的演化特点,表现为近圆形的重粒类型。
[Abstract]:By means of significant difference of characters, Euclidean distance comparison and grain shape discriminant function, 145 intact carbonized rice unearthed from the Neolithic site of Dabang Yingpanshan in Changning, Yunnan Province, were recovered into fresh rice. Through comprehensive analysis, it is concluded that the ancient rice in Yingpanshan, Baoshan Changning, belongs to the cultivated rice group of tilting japonica rice type, and belongs to japonica rice type in discriminant function and data index of distance measurement, and the difference between each character of Baoshan Changning Yingpanshan rice and that of reference system is very significant. The grain type is also different from that of modern japonica rice, and the evolution of grain type is characterized by short and thick grain type, which is characterized by near round heavy grain type.
