Türkiye’deki bazı Oleaceae türlerinde perforasyonlu özışını hücreleri

Öz

Türkiye’de Oleaceae familyası  Fraxinus L., Fontanesia Labill, Phillyrea L., Olea L., Osmanthus Lour., Ligustrum L., Jasminum L. olmak üzere 7 cins’e ait 14 doğal takson ile temsil edilmektedir. Familyanın Fraxinus dışındaki diğer cinsleri yalnızca bir takson ile yayılış göstermektedir. Oleaceae’nin bazı cins ve türlerinde perforasyonlu özışını hücreleri daha önce rapor edilmiş olsa da, Phillyrea latifolia L., Ligustrum vulgare L. ve Olea europaea L. türlerinde perforasyonlu özışını hücrelerinin varlığı ilk kez bu çalışma ile ortaya konulmuştur. İncelenen örneklerde, radyal çeperlerinde trahe hücrelerindeki gibi basit perforasyon tablası bulunduran, etrafındaki özışını hücrelerinden daha geniş olan perforasyonlu özışını hücreleri oldukça yoğundur.

Perforated ray cells of some oleaceae species in Turkey

Öz

Oleaceae family in Turkey, Fraxinus L., Fontanesia Labill., Phillyrea L., Olea L., Osmanthus Lour., Ligustrum L., Jasminum L. including 7 genus, is represented by 14 nature taxa, the others except Fraxinus are distributed in one species. Perforated ray cells in some species and genera of the Oleacaeae family have been previously reported. Perforated ray cells have been reported for the first time in Ligustrum vulgare L, Phillyrea latifolia L. and Olea europaea L. (Oleaceae) that grow in Turkey. In the specimens examined, the perforated ray cells are larger than the surrounding ray cells, more abundant and have a simple perforation plate in its radial walls similar to the vessel members.
