Analysis of Fe,Zn and Se Contents in Different Wheat Cultivars (Lines) Planted in Different Areas

The microelement contents of zinc (Zn),iron (Fe) and selenium (Se) in 62 wheat samples grown in different areas were determined by ICP-AES and atomic emission fluorescence spectrometry.The results showed that the Fe,Zn and Se contents were different in different wheat cultivars (lines) planted in different areas.Absorptions of the three elements by wheat affected one another.Zn and Fe promoted each other,while mutual inhibition was found between the absorptions of Zn/Fe and Se.It is concluded that both wheat genotypes and soil affected elements contents.Selecting microelement-rich genotypes is an important work for further wheat breeding.
