本试验以龙辐麦３号为材料，研究磷酸缓冲液通过花粉管通道导入小麦胚囊中的诱变效果，结果表明磷酸缓冲液对小麦有诱变效应，特别表现在小麦熟期上差异比较显著，在株高、主穗小穗数、千粒重性状上也有较大变异。磷酸缓冲液通过花粉管通道导入小麦胚囊的研究，将为小麦诱变育种创造一种新的处理途径 In this experiment, we used Longfumai 3 as material to study the mutagenic effect of phosphate buffer introduced into wheat embryo sac through pollen tube channel. The results showed that the phosphate buffer had the mutagenic effect on wheat, especially in wheat maturity Significantly, in plant height, the number of main spikelets, thousand grain weight traits have greater variation. Introduction of phosphate buffer into wheat blastocysts via pollen tube channels will create a new approach to mutation breeding of wheat
