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).
