【摘要】 通过对不同小麦品种高分子量谷蛋白亚基(HMW-GS)和低分子量谷蛋白亚基(LMW-GS)的分析表明;HMW-GS的含量及其比例与沉淀值呈正相关,Y型亚基主要起正向作用,而X型亚基主要起负向作用;A组亚基(HMW-GS)与B组亚基(LMW-GS-B)占谷蛋白的比例与沉淀值呈显著正相关,而C组亚基(LMW-GS-C)呈显著负相关,籽粒蛋白质含量的高低主要通过A和C组亚基比例的变化而影响品质。更多还原

【Abstract】 High and low molecular weight glutenin subunits of various wheat cultivars were analyzed with the following results. The content of high molecular weight glutenin subunits (HMW-GS) and its proportion were positively correlated with sedimentation value. The subunits of Y type had positive effects, while X type had negative ones. The proportion of subunit A group (HMW-GS) and B group (LMW-GS-B) of glutenin positively and significantly correlated with sedimentation value, while C group (LMW-GS-C) negatively. Grain protein content influenced wheat quality mainly by the changes of the proportion of A and C group subunits.更多还原
