Pollen morphology of Cornus mas L. and Cornus sanguinea L.

The pollen morphology of 2 species of the genus cornus l. distributed in turkey was studied with light and scanning electron microscope. the pollen of genus cornus is 3-colporate. pollen of the cornus mas is spheroidal and cornus sanguinea is subprolate. size varies of cornus mas pollen with the polar axis ranging from 21.54 to 27.36 μm and equatorial axis from 21.31 to 26.72 μm. size varies of cornus sanguinea pollen with polar axis ranging from 54.41 to 71.69 μm and equatorial axis from 46.03 to 63.42 μm. the equatorial outline of cornus mas pollen is triangular and cornus sanguinea pollen is circular. the results showed that pollen of these two species can easily be identified as species level.
