摘要
对八十土当遗址 T4 3( 18) 80 0 0年 b P的 2 0 0粒出土炭化米进行研究 ,证明炭化米的长、宽、厚缩变率分别为 5.36%、 2 .2 7%和 1.0 4 % ,炭化稻谷的长、宽、厚缩变率分别为 10 .71%、 3.0 3%和 2 .0 8%。复原后古栽培稻的粒形特征具有单一性状变异的广域性 ,性状组合的多型性 ,性状演化的近野性和原始性 ,是一种含有野、籼、粳基因的 。
The 200 carbonized rice of Bashidang remains T 43 (18) 8000 bP were studied. The reductional ratio of length, width and thickness of carbonized rice was 5.36%, 2.27% and 1.04 %, and for the carbonized grain was 10.71%, 3.03% and 2.08% were affirmed respectively. There fore, the ancient cultivated rice was restored from the carbonized rice had wide variation of a character, multitypes of character unite and the wildness of character evolution. It was a non wild. non indica and non japonica, dividing original cultivated rice type.
