小麦谷蛋白大聚合体含量的影响因素

小麦籽籽谷蛋白大聚合体（ＧＭＰ）的含量反映了谷蛋白聚合体的粒度分布情况，其高低与其他烘烤品质性状有密切的关系。本文对其影响因素进行了研究。结果表明，ＧＭＰ含量受Ｇｌｕ－１位点等位基因变异、亚基相对含量和环境因素等的影响。其中，Ｇｌｕ－Ａ１ｂ和Ｇｌｕ－Ｄ１ｄ对ＧＭＰ含量有正效应，而Ｇｌｕ－Ａｌｃ和Ｇｌｕ－Ｄ１ａ对ＧＭＰ含量有负效应；Ａ组和Ｃ组亚基的相对含量分别与ＧＭＰ含量正相关和负相关。ＧＭＰ含量也

Effects of Genetic and Environmental Factors on the Content of Glutenin Macropolymer

The effects of genetic factors and cultivation conditions on GMP content in common wheat ( T. aestivum L.) were studied in this paper. The results showed that the presence of Glu A1b and Glu D1d , the alleles at Glu 1 gene locus, associated with high GMP content while their allelic variations, Glu A1c and Glu D1a with low GMP content. The relative content of high molecular weight of glutenin subunits (i.e. group A) affected GMP content positively and that of group C of low molecular weight of glutenin subunits negatively. Also, different environments affected GMP content just like protein content and SDS sedimentation value.
