This method is used as the basis of identifying the two species. To research the effect of the morphological change of unearthed carbonized millet grains upon their identification, a test of artificial carbonization is carried out on caryopses of modern foxtail and broomcorn millets. The results indicate that, although the baked caryopese have blackened and a little decreased in size, the basic differences and distinctive features of the two species remain unchanged. The sharply-heated caryopses have been broken and their contents have distinctly swollen, but the embryo area remains intact and so still can be used as the morphological basis of specimen identification.展开更多
