Abstract

Mineral element contents of five wild rice were analyzed, including mineral nutrient elements such as phosphorus (P), potassium (K), calcium (Ca), sodium (Na), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), manganese (Mn) and selenium (Se), and the potential toxic elements arsenic (As), mercury (Hg), lead (Pb) and cadmium (Cd). The results showed that the contents of K, Mg, Fe, Zn, Cu, Mn and Se in five wild rice materials were much higher than the cultivate variety Zhou 903 in both brown and milled rice. Wild rice also had lower potential toxic element contents of Hg, Pb and Cd compared with Zhou 903 in brown rice and milled rice, respectively. Among five wild rice samples, WR-3 from Uganda had the highest level of P, K, Ca, Na, Mg, Fe, Zn, Mn and Se, and the lowest contents of Hg, Pb and Cd.

摘要

对 5 种野生稻的矿质元素含量进行了分析，包括磷（P）、钾（K）、钙（Ca）、钠（Na）、镁（Mg）、铁（Fe）、锌（Zn）、铜（Cu）、锰（Mn）和硒（Se）等矿质营养元素，以及砷（As）、汞（Hg）、铅（Pb）和镉（Cd）等潜在有毒元素。结果表明，5 种野生稻材料糙米和精米中的 K、Mg、Fe、Zn、Cu、Mn 和 Se 含量均明显高于栽培品种周 903。与周 903 相比，野生稻糙米和精米中的潜在有毒元素 Hg、Pb 和 Cd 含量也较低。在 5 个野生稻样本中，乌干达的 WR-3 具有最高水平的 P、K、Ca、Na、Mg、Fe、Zn、Mn 和 Se，以及最低水平的 Hg、Pb 和 Cd。
