摘要
对147个小麦高代育种材料的全粉SDS沉淀值及其与面团揉混特性参数和Zeleny沉淀值的相关性进行分析,结果表明:SDS沉淀值与形成时间和峰值宽度均为正相关,相关系数分别为0.75和0.46,与衰落角为负相关,相关系数为-0.62;SDS沉淀值与Zeleny沉淀值为显著的正相关,相关系数达0.77。这说明全粉SDS沉淀值能够在一定程度上反映面团的耐揉性和弹性,且与Zeleny沉淀值反映的蛋白质特性在很大程度上是一致的。因此,全粉SDS沉淀值可以作为面粉品质快速评价的指标,特别是在种子量较少的小麦育种筛选世代。
The SDS sedimentation value of whole meal of 147 advanced wheat lines were detected and its correlation with mixograph characteristics and Zeleny sedimentation value were also analyzed.The SDS sedimentation value was positively correlated to development time and peak width with the correlation coefficients as 0.75 and 0.46 respectively.The negative correlation between SDS sedimentation value and weakness degree was found with the correlation coefficient as-0.62.The significant positive correlation was showed between SDS sedimentation value and Zeleny sedimentation value with the correlation coefficient as 0.77.All these indicated that the SDS sedimentation value of whole wheat meal could be used to deduce the dough flexibility and elasticity to a certain degree,which showed high consistent with the protein characters deduced by Zeleny sedimentation value.Therefore,the SDS sedimentation value of whole wheat meal could be used as one rapid evaluation indicator of wheat quality,especially for those progenies with small amount of seeds during the breeding process.
