摘要
用欧氏距离比较、粒型判别函数等方法,对广西资源晓锦遗址第二期出土的154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:晓锦二期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。在形态上最近于粳稻,与普通野稻最远,表明己是栽培稻。该群古稻与参照系差别较大,粒型大而重。
154 complete carbonized rice grains from Xiaojin ruin II of Ziyuan County in Guangxi were restored by calculation and compared with O.rufipogon, other ancient rice, indica and japonica in grain shape, character difference and Euclidean distance coefficient. The result indicates that Xianjin ruin II ancient rice belongs to the group of trend-japonica type ancientrice. Discriminant function and distance measurement data indicators belong to japonica. These rice are closer to the character of japonica, but far from common O.rufipogon; which indicate that they are O.sativa. This group of ancient rice differs much from the reference systems, because every rice is big and heavy.
