| Abstract: | Morphological characteristics, of three peony species, Paeonia rockii; Paeonia suffruticosar and Paeonia ostii were compared using slanning electron microscope including seven vavisties. The taxonomic significance of these characteristics and evolufional relationship among these three species were discussed.The results showed there were certain interspecific differences among the three species on the basis of the morphology, size and exine sculpture of pollen grains. |
