蔬菜是补充人体微量元素的重要途径,但是蔬菜不同部位、特别是温室蔬菜不同部位各种元素的分配目前还没有研究清楚.利用同步辐射XRF法测定了温室油菜中各种微量元素中的分配情况.研究结果表明温审油菜中含有许多人体必需的微量元素,特别是Ca,Mn,Fe,Cu和Zn;但是不同的元素在叶片和根系的不同部位含量有所差异,总体上油菜根系中K,Ca和Mg的含量显著高于叶片,叶片中Fe,Zn,Co,Ni和Cu的含量则高于根系,其中侧根中的各种元素含量均很低.K,Ca和Co在叶片中间位置含量较高,由边缘向中部含量逐渐增加;Cu,Mn,Fe和Ni含量由叶片基部到叶尖处含量逐渐增高;Zn总体含量也比较均匀.在主根中各种元素普遍表现为根基部向根尖呈现先上升再降低的规律,根系中间部位各元素含最高,且普遍表现为根基部的含量要高于根尖处的含量.

The trace elements distribution in the root and leaf of greenhouse rape was determined with synchrotron radiation XRF,and many essential elements for human health were found,including Co,Mn,Ni,Fe,Cu,Zn,K and Ca,among which the contents of Ca,Mn,Fe,Cu and Zn are especially higher than the other elements.The results proved that the contents of different elements in different parts of leaves and roots were inequable.Generally,the contents of K,Ca and Mg in the roots are significantly higher than those in leaves,while the contents of Fe,CO,Ni,Cu and Zn in the leaves are apparently higher than those in roots.And the contents of all the elements in lateral roots are much lower.The contents of K,Ca and CO in the central section of leaf were higher than those in the edge,and the contents are gradually increasing from the edge to center;the contents of Cu,Mn,Fe and Ni in the tip of leaf were higher than those in base,and it increases gradually from the base to the tip of leaf;the content of Zn in the leaf is absolutely uniform;all the elements in the middle of root were higher than those in two ends,and the contents in the base of root are commonly higher than those in the tip of root.
