摘要 通过徒手切片观察了红色水稻色素着生位置,并用等离子体质谱仪、原子吸收光谱仪测定了四种微量元素(Fe、Zn、Se、Ge)的含量,比较红宝石、杂交红米和普通白米中微量元素含量,以确定其营养差异.实验结果如下:①其色素主要存在种皮和果皮中;②微量元素铁(Fe)、锗(Ge)主要存在糙米的种皮和果皮中;③红宝石糙米中各微量元素含量和四种微量元素总含量均高于普通白米,说明红宝石营养成分含量高,并且由其遗传特性所决定.微量元素锗(Ge)、硒(Se)含量在杂交红米中与亲本常规红米中的含量持平,说明通过杂交方法来提高保健稻产量,降低其生产成本是有效的,因此红宝石是很有利用潜力的优质保健稻米资源. The location of the pigment was identified with hand-slide in the paper. Using plasma mass spectrograph and atomic absorption spectrometer to determine the amounts of Fe, Zn, Se and Ge, the aim is to compare the nutrient difference among the red rice, hybrid red rice and the common rice. The results were as follows: (1)The pigment was mainly in the seed coat and pericarp. (2)Fe and Ge was mainly in the seed coat and pericarp. (3)The red rough rice was more than common rice of the contents of every microelement and total contents of the four microelements. The hybrid red rough rice was more than common rice too. It was improve the yield and reduce the cost of health care rice because the nutrient of red rice was controlled by heredity. The red rice is potential resource of health care rice with high quality.
