红米色素与微量元素硒之间关系的初步研究

Preliminary Study on Relationship Between the Pigment and the Contents of Microelement Selenium in Red Rice

利用3个富硒红米材料R319、R329、红宝石分别与白米材料蜀恢527、621A杂交配成6个组合,并随机抽取其F2植株上所获得的红、白糙米样本各50份进行硒元素含量检测。结果显示,红糙米的硒含量平均值显著大于白糙米。对红米品种(红宝石)的糙米,按其着色深浅不同分别进行检测,发现其硒含量随着着色程度的升高而增加。结果表明:红米色素与微量元素硒含量之间存在着一定的关联,红米的富硒能力要大于白米。

The white rice shuhui527 and 621A crossed with three selenium-rich varieties of red rice R319,R329 and ruby,respectively.Selenium content in the red and white brown rice from the F2 of 50 samples’ were determined respectively.The results showed that the average selenium-content of red brown rice was significantly higher than that of white brown ones.To the brown rice of the red rice varieties（ruby）,content of selenium were determined according to color shades,and selenium content increased with the degree of the color.This study indicated that there were certain relation between the red pigment and the contents of microelement selenium.The ability of accumulating selenium of the red rice was stronger than that of the white ones.
