    摘要:

    用AAS方法测定了弥勒县相同生态条件下种植的27份有色稻和34份普通稻糙米4种矿质元素含量,并对有色米和普通米Fe、Zn、Cu和Mn含量进行了比较研究。结果表明,有色稻米4种矿质元素含量明显高于无色稻米,其差异均达显著水平,其含量高低依次为Zn>Fe>Cu>Mn;对黑、褐、红、黄、绿5种不同种皮颜色的稻米4种矿质元素含量进行比较研究,发现稻米Fe含量(mg/kg)依次为黑>绿>褐>红>黄,Zn含量(mg/kg)依次为绿>红>黑>褐>黄,Cu含量(mg/kg)依次为黑>褐>红>黄>绿,Mn含量(mg/kg)依次为褐>黑>红>黄>绿;并且Fe和Mn含量在不同颜色稻米间差异均达显著水平,与有色米种皮颜色密切相关,而Zn和Cu差异不显著,与有色米种皮颜色关系不大。黑米和褐米富Fe、Zn、Cu和Mn,绿米富Fe和Zn,红米富Zn和Cu,黄米4种矿质元素含量较低,Fe、Cu和Mn均低于普通稻米。

    Abstract:

    The different color rice were evaluated based on four mineral concentrations of brown rice from 61 accessions harvested from Mile experiment farm under the uniform ecological conditions by AAS method. The results showed that the Fe, Zn, Cu and Mn concentration of the color rice was higher than that of the write rice, and the four mineral concentrations in brown rice was Zn > Fe > Cu > Mn. In addition, Fe and Zn concentration of color rice were affected by pigment content in pericarp of it, Cu and Mn of color rice were not influenced by pigment content in pericarp of it. Fe concentration of the color rice was in turn black rice>green rice>brown rice>red rice>yellow rice, Zn concentration of the color rice was in turn green rice > red rice > black rice >brown rice >yellow rice, Cu concentration of the color rice was in turn black rice>brown rice >red rice>yellow rice >green rice, Mn concentration of the color rice was in turn brown rice >black rice> red rice>yellow rice >green rice. There were some differences among Fe, Zu, Cu and Mn average concentrations in brown rice of the different color rice, black rice and brown rice rich on Fe, Zn, Cu and Mn, green rice rich on Fe and Zn, red rice rich on Zn and Cu. Four concentration of yellow rice were lower than that of the other color rice.
