作者对~(65)Zn在小麦中的几项示踪技术一茎部注射~(65)Zn,茎部注射~(65)Zn+ZnSo_4,叶面施用~(65)Zn和含~(65)Zn的溶液培养进行了比较。测定小麦颖果中~(65)Zn,结果分别为:茎部注射~(65)Zn,占注射量的62.6%;茎部注射~(65)Zn+ZnSO~4,占注射量的45.2%;叶面施用~(65)Zn,占施用量的57.5%;含~(65)Zn的溶液培养,占加入量的2.3%。全株小麦制成干粉末,脱脂后提取四种蛋白质成分,各处理中的蛋白质~(65)Zn的分布量为;清蛋白和球蛋白中为8.5～20.3%;谷蛋白中为47.4～60.3%,麦醇溶蛋白中为1～2.6%,其它蛋白质中为9.8～28.3%。用凝胶层析法分离,结果表明:各处理与对照,其蛋白质成分相似,Zn的分布相似。且~(65)Zn
Several tracers of ~ (65) Zn in wheat were inoculated with ~ (65) Zn in the stem, ~ (65) Zn + ZnSo_4 in the stem and ~ (65) Zn and ~ ) Zn solution was compared. The results showed that the content of ~ (65) Zn in wheat caryopses was (65) Zn, which accounted for 62.6% of the injected amount, and the content of Zn + ZnSO 4 in the stem was 45.2% (65) Zn, accounting for 57.5% of the applied amount; and the solution containing ~ (65) Zn, accounting for 2.3% of the added amount. The whole wheat was made into a dry powder, and four protein components were extracted after degreasing. The distribution of ~ (65) Zn in each treatment was 8.5-20.3% for albumin and globulin and 47.4-60.3 for gluten %, 1 to 2.6% for gliadin and 9.8 to 28.3% for other proteins. The results of gel chromatography showed that the protein components were similar in all the treatments and controls, and the distribution of Zn was similar. And ~ (65) Zn
