Palynological study of five genus of tribe Anthemideae (Asteraceae) in Iran

The pollen grains of 13 populations from 5 genera belonging to the tribe Anthemideae-Asteraceae (one to three pulations of each species) from Iran were studied by light and scanning electron microscopy. Pollen grains of all the samples studied were tricolporate. The pollen grains with oblate-spheroidal and spheroidal shapes were common among the genera studied. All genus have pollen grains of Anthemis-type .The pollen ornamentations were echinate perforate in SEM. The results showed that pollen micromorphological characters could be utilized in interpretation of intergeneric relationship of tribe Anthemideae. Also, pollen size and shape determined as taxonomic diagnostic characters
