Mineral elements are nutrients required by an organism to perform functions necessary for survival. Stress-induced metabolism following nutritional stress has been reported to increase levels of anthocyanin. However, the role of mineral elements commonly found in soil and their contribution to the accumulation of anthocyanin content in rice plants is uncertain.
Amongst the ten mineral elements investigated, the cultivation of rice plants in clean sand showed that the Mg-, Se-, and Cu-treated plants had the highest accumulated anthocyanin content in the leaves, whereas B, Cr, and Se had the greatest effect on grains. Yield component data showed major positive effects from Mg, Cr, and B. The interaction of ZnSe and MgCu positively affected the anthocyanin content in grains. The self-organizing map indicated that the total anthocyanin content was relatively proportional to the concentration of Mn, B, and Cr, but disproportional to that of Se. However, rice plants with added Fe produced the smallest amount of total anthocyanin content, less than the control, in the four stages of rice growth.

矿物质元素是生物体生存所必需的营养物质。据报道，营养胁迫后应激引起的代谢会增加花青素的水平。然而，土壤中常见的矿物质元素及其对水稻植物中花青素含量积累的作用尚不确定。
在所研究的十种矿物质元素中，在清洁沙中种植水稻表明，Mg、Se 和 Cu 处理的植物叶片中积累的花青素含量最高，而 B、Cr 和 Se 对谷物的影响最大。产量构成数据显示，Mg、Cr 和 B 有较大的积极影响。ZnSe 和 MgCu 的相互作用对谷物中的花青素含量有积极影响。自组织映射表明，总花青素含量与 Mn、B 和 Cr 的浓度成正比，但与 Se 的浓度不成比例。然而，在水稻生长的四个阶段，添加 Fe 的水稻植物产生的总花青素含量比对照少。
