The pollen morphology of some important and attractive plants for bees from Kermanshah province

In this research, pollen morphology of 10 species of 8 attractive plants for bees were studied using SEM microscopy from different parts of Kermanshah province. The methods used in this study included: 1- Field visit and pollen collection directly from the flowers; 2- Using the trapping device installed in front of the hive lid; 3- Removing the pollen from the inside of the hive. Several reference books and relevant websites were used for pollen identification. Results showed that the majority of pollen grains had medium size but there were few large and very large pollen grains. Their shape was prolate - spheroidal, prolate and the outline of pollen grain is as the oblate-spheroidal form in polar view and as an elliptical from in equatorial view. The position of aperture in studied pollens were monosulcate, tricolpate, tricolporate, monoporate and pantoporate. The exine ornamentation were reticulate, striate, granulate, psilate, echinate. Also, the highest pollen collected by the bee was, respectively, Asteraceae, Rosaceae, papilionaceae and Apiaceae.
