| 摘 要： | 以生长于田间的玉米掖单13(耐旱性玉米)和丹玉13(不耐旱性玉米)为试验材料,应用ICP对供试玉米的初生根和第一、二、三、四、五、六、七、八和第九层次生根的铁、锰、铜、锌和钠元素含量等项指标进行了测定和比较分析。结果表明:除个别根外,耐旱性玉米不同类型根中的铜含量极显著高于不耐旱性玉米根系(P0.01);根中的锰元素含量和锌元素含量极显著高于不耐旱性玉米根系(P0.05);根系中铁元素含量和根系中的钠元素含量在两品种玉米根系之间差异未达显著水平(P0.05)。

| Abstract: | The primary roots and the first to ninth layers of secondary roots of two maize genotypes of Yedan-13(drought tolerance) and Danyu-13 non- drought tolerance) with different tolerance to drought in the field condition were investigated to study their content of iron, manganese, copper, zinc and sodium by ICP. The results showed that the
content of copper of Yedan-13 was higher than that of Danyu - 13 at extremely significant difference level(P< 0.01). And the content of manganese and zinc of Yedan - 13 was also significantly higher than that of Danyu- 13(P< 0.05). However, there were no significant differences in the content of iron and sodium of root between the two genotypes (P>0.05). |
