title: [Observation and comparision on morphological characteristics of pollen of Lonicera japonica in different cultivars].
abstract: OBJECTIVE
  To compare morphological characteristics of pollen of Lonicera japonica in different cultivars cultivated in Shandong and provide a basis for distinguishing different cultivars and selecting fine breeding.
  
  
  METHODS
  The scanning electron microscope (SEM) was applied to observe and compare the outside characteristics of pollen,and the data were analyzed by SAS 9.1 software.
  
  
  RESULTS
  Some difference was found among pollen size, aperture length and the density of spine. The biggest pollen size and aperture length is Dajizhao with 61.97 microm polar axis and 61.79 microm quarter major axis and 18.03 microm aperture length,and the smallest is Honggengzi with 57.46 microm polar axis and 57.29 microm quarter major axis and 18.03 microm aperture length.
  
  
  CONCLUSIONS
  The morphological characteristics of pollen can provide a basis for distinguishing different cultivars of L. japonica.
