Study of pollen morphology of some Solanum L. (Solanaceae) species in Iran

Solanum L. is the largest genus of Solanaceae that consisting of about 1400 species all over the world. The morphology of pollen grain from 6 species of Solanum was examined. The size, shape, polar area, polar view, equatorial view, aperture type, colpus features, sexine ornamentation of pollen grains were studied in detail using light microscopy (LM) and scanning electron microscopy (SEM). This investigation revealed spheroidal to subprolate shape, the tricolporate nature and the granular surface sculpturing, typical of Solanun pollen. The three colpi were distinct and deeply infolded or closed. Our study determined that the possible diagnostic value of various micromorphological characters in the differentiation of taxa belonging to this genus
