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,对亚公山遗址出土的200粒炭化稻米,经过复原为新鲜稻谷后,通过综合分析认为:亚公山古稻的综合性状特征已远离普通野稻和早期原始古栽培稻,更趋近栽培水稻中的粳亚种类型.其群体平均值的粒型判别为粳型,已倾向粳稻粒型方向演化.其在演化过程中,向大粒化方向演变.其属性皆趋向粳稻类型,而且粒大较重.这些特征与距今6000年前的城头山古稻和4000年前的后大堂古稻相似,而与现代岭南地区广泛种植的籼稻不同.
Two hundred complete carbonized rice grains from Yagongshan ruins 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 the general characters of Yagong Mountain ancient rice differ from common wild rice and early original ancient cultivated rice, which are simi- lar to japonica type of cultivated rice. The group average of character difference is japonica, which has the e- volution of tendency to japonica type rice. In the process of evolution, its direction of evolution enlarges and its property having tendency to japonica type with bigger and heavier grains. These characters are similar to the ancient rice in Chengtoushan （6000 years ago） and Houdatang （4000 years ago）, however, differing from, widely cultivated, indica type rice in present Lingnan areas.
