摘　　要：本研究采用SDS—PAGE分析了冀麦七号、冀麦18和冀早15三个品种激光后代籽粒贮藏蛋白的变异情况。结果表明,高分子量麦谷蛋白和醇溶蛋白亚基变异较小,其控制位点为Glu—1和Gl—3或Gli—1;而低分子量部分变异较大,其控制位点多在Glu—3、Gli—2和Gli—3。这些变异具有一定的随机性。有关激光诱变对小麦面粉品质的影响有待进一步研究。Variation of seed storage protein subunits from laser treatment offsprings of Jimai 7, Jimai 18, Jizao 15 was analyzed by SDS-PAGE. The resault showed that mutation is less in the HMW glutenins and gliadins (coded by Glu -1,Glu-3 and Gli-1) and more in the LMW subunits (coded by Glu-3,Gli-2 and Gli-3). And the mutation is random. A further study is needed on the influence of wheat grain quality by laser treatment.
