[Objective] To compare the morphological characteristics of the pollens of 13 germplasms of Lonicera japonica, and to provide reference for the classification of germplasms and the breeding of high-quality cultivars. [Method] Morphological characteristics of the pollens were observed by scanning electron microscope; data were analyzed by SPSS statistical software. [Result] There were significant differences in the pollen size and spike density of different germplasms of L. japonica. And the 13 germplasms of L. japonica could be divided into 6 categories. [Conclusion] The pollen size and spike density could be used as the references to divide different germplasms of L. japonica.
