چکیده مقاله:

The presence of some unique traits in pollen grains such as diversity in shape, surface ornamentation of Exine and a large number of pollen grains produced per plant has caused the attention of botanists to study pollen grains. The Asteraceae family is a group of natural plants with unique morphological characteristics such as pollen grains. The Chamomile (Anthemis) belongs to the Asteraceae family. The purpose of this research was the investigation of pollen morphology of three species Anthemis widemmaniana, Anthemis truimfetti (L.) D.C. and Anthemis tinctoria L. using scanning electron microscopy. The surface of exine was echinate with small pores in the base. The results showed that the shape of the pollen grain of Anthemis widemmaniana was elongated and in some samples of Anthemis tinctoria and Anthemis truimfetti was spherical and in some elliptical. Average pollen grain diameter of Anthemis widemmaniana, Anthemis tinctoria,and Anthemis truimfetti was 24.51, 23.41-23.76 and 22.78- 22.90, respectively. Colpus length in the species Anthemis widemmaniana, Anthemis tinctoria and Anthemis truimfetti was 5.51, 4.5 and 4.23 μm, respectively. Therefore, variation in shape, pollen diameter, and pollen grains length were observed among studied species
