禾本科3个物种花粉粒及叶片扫描电镜观察

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 tritical were 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 scientific references to identify new multiploid species created by chromosome engineering.
