The Measurement of the Contents of the Trace Elements by the Method of Flame Atomic Absorption Spectrometry (FAAS) in grape(Vitis vinifera Linn.)
The contents of Fe,Zn,Mn,Cu,Cr,Ni elements of the organs were measured by the method of flame atomic absorption spectrometry(FAAS)in 12 cultivars of grape from Sanming.The result showed that,six trace elements existed in all the organs of grapevine.The contents of these trace elements differed to some extent among different organs,trees or cultivars.Among them,the contents of the trace element(Fe、Mn)in the organs of grape were relatively high;The contents of Zn、Cu was the second in the organs of grape;The contents of the trace element(Ni、Cr)were relatively lower levels in the organs of grape.The contents of Fe,Mn,Zn,Cu of most organs in grape belonged to normal contents of the trace elements in plants,but the contents of Cr,Ni is slightly higher than that of the general plants.The variance of Fe content in 12 grape cultivars was the most obvious,the size order of Fe content is TengrengJufengJingyaShuangweizaohongtiHonggaoHeixiangjiaoJingxiu87-1TangmuxunJinxinwuheShifuluoshaWeiduoliya,but the contents of Ni、Cu、Cr in 12 grapevine cultivars have little difference.
