【摘要】 水稻稃壳双峰乳突,纵列横行排列有序,是鉴别籼、粳亚种的主要性状之一;在缺乏古稻谷的情况下,稻壳印痕也不失一种鉴别古稻的方法。用此方法对100片石峡遗址M104古稻稃壳双峰乳突印痕的研究,确认石峡古稻是一个处于籼、粳分化,属性模糊的杂合种群,是古稻演化历史阶段的反映。石峡古稻所呈现的籼、粳模糊性和分化状态特征,表明石峡古稻是我国栽培稻起源与发展史上承上启下的重要一环。更多还原

【Abstract】 The Bi-peaked Tubercles on rice,arranged in a clear order,is one of the major characteristics helpful to distinguish different kinds of rice.In the case of being lack of ancient rice,the signs of ancient rice shell are also a good way for the differentiation of ancient rice,and can contribute a lot in understanding the characteristics and evolution state of ancient rice;useing this method,complementary effects will be produced.According to the survey of 100 husks of ancient rice in Shixia ruins,the author confirms that the kind of rice is a mixed category and it reflects the developing way of the ancient rice.Unclearness and dividedness reflected in the ancient rice,demonstrate that the ancient rice in Shixia ruins has played an important role in the origin and evolution of the cultivated rice,and prove to be valuable to the research of the origin and evolution law of the cultivated rice in Lingnan and across the country.更多还原
