Cornus mas L. ve Cornus sanguinea L. türlerinin polen morfolojisi

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

Cornus mas L. ve Cornus sanguinea L. turlerinin polen morfolojisi Ozet: Turkiye’de yayilis gosteren Cornus L. cinsinin 2 turunun ( Cornus sanguinea L. ve Cornus mas L.) polen morfolojisi isik ve taramali elektron mikroskobuyla calisilmistir. Cornus cinsinin polenleri trikolporat aperture sahiptir. Cornus mas ’in polen sekli sferoid iken Cornus sanguinea ’nin ise subprolat’dir. Cornus mas polenlerinin polar eksen uzunlugu 21.54-27.36 μm ve ekvatoral eksen uzunlugu 21.31-26.72 μm arasinda degismektedir. Cornus sanguinea polenlerinde ise polar eksen uzunlugu 54.41-71.69 μm ve ekvatoral eksen uzunlugu 46.03-63.42 μm arasinda degismektedir. Cornus mas ’in ekvatoral dis gorunusu ucgenimsi iken Cornus sanguinea ’nin ise dairemsidir. Elde edilen sonuclar bu iki turun polenlerinin kolaylikla ayirt edilebilecegini gostermistir.
