    摘要:

    研究小麦及其土壤中微量铬的相关性,为富铬小麦品种的选育和富铬功能性食品的开发提供科学依据。用微波消解样品,建立流动注射化学发光法测定彩色小麦、普通小麦以其土壤中铬含量的方法。结果表明:在五个地区种植的六个品种小麦,铬含量在0.126 3~0.451 6 μg /g之间。不同品种小麦的铬含量有所不同,普通紫麦的铬含量较高;同一品种小麦在不同地区种植,其铬含量也不同,商丘地区小麦铬含量较高。在同一生长环境下,不同品种的小麦铬的生物吸收比不同, 普通紫麦的生物吸收比较大,商丘地区种植的普通紫麦的生物吸收比高达27.62%,是补充铬的理想原料,有一定的培育前景。

    Abstract:

    The relationship between wheat and trace chromium in soil was studied in order to provide a scientific basis for the breeding of wheat varieties enriched in chromium and development of functional food with rich chromium. With applications of microwave digestion sample, the determination method of chromium content in color wheat, common wheat and soil was established by flow injection chemiluminescence. The results showed that in six varieties of wheat grown in five areas, the chromium content was between 0.126 3~0.451 6μg /g. Different varieties had different content of chromium, chromium content in common purple wheat was higher; the same varieties of wheat planted in different area, the chromium content was different. Wheat planted in Shangqiu the chromium content was higher. Under the same growth environment, different varieties of wheat had different chromium biological absorption ratio, common purple wheat had higher biological absorption ratio, the biological absorption ratio of the common purple wheat planted in Shangqiu was as high as 27.62%, which was an ideal natural raw material to supplement chromium and had a certain cultivation prospects.
