In this study, we investigated the starch properties of Aegilops sharonensis (R7), tetraploid wheat (Z636), and their amphidiploid (Z636 × R7). The results of protein electrophoresis showed that waxy protein of Ae. sharonensis (R7) and tetraploid wheat (Z636) is expressed in the amphidiploid (Z636 × R7). The total starch content and amylose content of the amphidiploid (Z636 × R7) were higher than Ae. sharonensis (R7) and lower than tetraploid wheat (Z636). The amphidiploid (Z636 × R7) exhibits an intermediate type of starch granules morphology that the ratio of A/B-type starch granules and their shapes ranged between Ae. sharonensis and tetraploid wheat. The gelatinization parameters showed that the concluding temperature (Tc) and enthalpy change (ΔH) of Ae. sharonensis (R7) were significantly lower than those of tetraploid wheat (Z636) and the amphidiploid (Z636 × R7), while the values of onset temperature (To) and peak temperature (Tp) were similar among the Ae. sharonensis (R7), tetraploid wheat (Z636), and the amphidiploid (Z636 × R7). For the aging properties, the ΔH values of Ae. sharonensis (R7) and the amphidiploid (Z636 × R7) were close but lower than that of tetraploid wheat (Z636), whereas the parameters of To, Tp, and Tc did not differ significantly among three materials. The amphidiploid (Z636 × R7) possesses varied starch properties from wheat, which may be useful in wheat quality improvement.

在这项研究中，我们调查了沙棘鸡（R7），四倍体小麦（Z636）及其两性类（Z636×R7）的淀粉特性。蛋白质电泳结果显示蜡状蛋白质为Ae。Sharonensis（R7）和四倍体小麦（Z636）在二倍体（Z636×R7）中表达。二倍体（Z636×R7）的总淀粉含量和直链淀粉含量高于Ae。沙龙（R7）低于四倍体小麦（Z636）。二倍体（Z636×R7）表现出一种中间类型的淀粉颗粒形态，即A / B型淀粉颗粒的比率及其形状介于Ae之间。沙龙和四倍体小麦。糊化参数表明Ae的最终温度（Tc）和焓变（ΔH）。沙龙（R7）显着低于四倍体小麦（Z636）和两性小麦（Z636×R7），而Ae的开始温度（To）和峰值温度（Tp）值相似。沙龙（R7），四倍体小麦（Z636）和两倍体（Z636×R7）。对于老化性能，Ae的ΔH值。沙龙（R7）和二倍体（Z636×R7）接近但低于四倍体小麦（Z636），而To，Tp和Tc的参数在三种材料中没有显着差异。二倍体（Z636×R7）具有与小麦不同的淀粉特性，这可能有助于改善小麦的品质。
