摘　　要：The pollen grain morphology and leaf epiderm shape and microstructural of Rye（ Secale cereal ）, common wheat and Octoploid Trititrigia were observed with the scanning electron microscope（SEM）. The results revealed that there were great differences between pollen and leaf epiderm microcosmic morphology in three species. Such characteristics of Octoploid tnticalwere between those of common wheat and Rye. The morphology of pollen grain and leaf epiderm shape counld be used as an index for taxonomy for genera and species, and had somewhat scientif- ic references to identify new multiploid species created by chromosome engineering.以普通小麦（2n=6x=42）作母本，与二倍体黑麦（2n=2x=14）进行杂交，并进行染色体加倍，所获得的新物种就是八倍体小黑麦（2n=8x=56）。八倍体小黑麦的植物学形态介于双亲之间，兼有两者的性状。
