普通小麦品种籽粒矿质元素含量分析

山西省中部地区是山西小麦生产的重要地区，了解该区当前主栽小麦品种和骨干亲本的籽粒中矿物元素含量的基因型特点，对进一步选育富含铁、锌等元素的新品种具有指导作用。采用电感耦合等离子发射光谱仪(ICP-AES)分析了17个小麦品种的铁、锌、锰和铜元素含量。结果表明，供试材料中4种元素含量的变化范围较大，铁、锌、锰和铜的平均含量分别为38.19 mg/kg、29.30 mg/kg、38.44 mg/kg和6.89 mg/kg。其中，‘河东乌麦526’、‘京冬8号’和‘冬黑10号’的铁含量大于45 mg/kg，‘太10604’的锌含量最高为42.98 mg/kg，‘河东乌麦526’和‘冬黑10号’锰含量高于45 mg/kg，‘晋麦66’和‘冬黑10号’铜的含量较高，均高于8.50 mg/kg。籽粒中锰与铁、锰和锌元素含量间呈显著相关，其中锰和锌含量间呈极显著相关，相关系数为0.69，其他各元素间相关不显著。可以从小麦主栽品种中筛选高矿质元素含量的基因型，‘河东乌麦526’、‘京冬8号’、‘冬黑10号’和‘太10604’ 4个品种可作为进行籽粒富含铁、锌矿质营养小麦遗传改良的亲本。

Mineral Elements Concentration Analysis on Major Wheat Cultivars in Central Shanxi Province

The central region of Shanxi Province is very important for wheat production.Understanding the major mineral elements concentration of these cultivars and core parents will provide useful information for wheat nutritional breeding.The iron (Fe),zinc (Zn),manganese (Mn),copper (Cu) of 17 varieties/lines were investigated by an inductively couples plasma atomic emission spectroscopy (ICP-AES).The results showed that the 4 mineral elements content appeared to have a great variation,the mean grain content of Fe...
