普通小麦、小黑麦和黑麦花粉粒及其叶表皮结构的扫描电镜观察

Scanning Electron Microscope Observation on Pollen Morphology and Leaf Epidermis in Wheat, Triticale and Rye

普通小麦、小黑麦和丹麦黑麦在花粉粒形状。花粉粒表面纹饰和叶表皮结构等方面存在显著差异。小黑麦的上述特征介于普通小麦和丹麦黑麦之间。因此,花粉粒形状及其表面纹饰特征和叶表皮结构特征可能适于作为种属分类的重要依据之一,对新物种的鉴定和确定物种间的亲缘关系也有参考意义。

There are significant differences in the shape of pollen grains, the ornamentation of pollen grains and the structure of leaf epidermis among wheat, triticale and Denmark rye. Such characteristics of triticale are between those of wheat and Denmark rye. So, the characteristics described above may be used for taxonomy for genera and species. They are also of significance in identification of new species and determination of kinship in different species.
