Research on the Characteristics of the Heavy Metal-Cu Accumulation in Wheat Plants

WEI Xin et al(College of Environment and Survey/Mapping,China Mining University,Xuzhou,Jiangsu 221116)  
[Objective] The characteristics of the heavy metal-Cu distribution in the wheat and its accumulation were understood.[Method] The amount of Cu accumulation in the different organs in seedling,elongation,heading and mature stage of wheat was tested under the treatment of the different concentrations of Cu solution added in the soil grown with wheat.The characteristics of heavy metal-Cu enrichment in wheat plant were analyzed and the effect of the content of the heavy metal-Cu in wheat grain on the human life was determined.[Results] The results showed that most of Cu was accumulated in wheat root and little,in aerial part of wheat plant.The content of Cu in root,stem and leaf of wheat was highest in wheat elongation stage.There was little variation in the content of Cu in wheat glume and grain in heading and maturity stage within the range of treatments.The content of Cu in grain in wheat maturity stage was met the requirement of the Safety Standard of China′s Non-polluted Food.[Conclusion] The content of Cu accumulation in the different parts of same wheat growth period,as well as in different periods in same part of wheat was different.
