Abstract:

 In this study, pollen morphologies of 5 species Astragalus guttatus Banks  Sol., A. cretaceus Boiss., A. caprinus L., A. brachystachys DC. and A. ancistrocarpus Boiss.  Hausskn. belonging to the Astragalus genus of the family Fabaceae, which are distributed in Şanlıurfa province, were exemined by light and electron microscope. As a result of the study, it was determined that the pollen of the taxa were monad, radial symmetrical and isopolar. Pollen of all studied species are trizonocolporate, colpus length Clg 16.5-27.62 µm, colpus width Clt 2.15-4.16 µm, pore length Plg 6.69-9.32 µm, pore width Plt was detected between 6.69-11.44 µm. Polar axis length was measured between 19.23-33.66 µm and equatorial axis diameter was measured as 14.95-28.61 µm. Ornamentation was determined as psilate, psilate-perforate, psilate-microreticulate, microreticulate in the polar region and aperture surround the while microreticulate in the equatorial region. As a result of the study, it was determined that the characters such as pollen shape, pollen size and surface ornamentation differ between species and these characters have taxonmic value in the systematic separation of species.

 Bu çalışmada, Şanlıurfa ilinde yayılış gösteren Fabaceae familyasından Astragalus cinsine ait 5 türün Astragalus guttatus Banks  Sol., A. cretaceus Boiss., A. caprinus L. subsp. caprinus, A. brachystachys DC. ve A. ancistrocarpus Boiss.  Hausskn. polen morfolojisi ışık ve elektron mikroskopları ile incelenmiştir. Çalışma sonucunda taksonlara ait polenlerin monad, radyal simetrili ve izopolar oldukları tespit edilmiştir. Çalışılan tüm türlerin polenleri trizonokolporat olup kolpus uzunlukları Clg16,5-27,62 µm, kolpus genişlikleri Clt 2,15-4,16 µm, por uzunlukları Plg 6,69-9,32 µm, por genişlikleri Plt 6,69-11,44 µm arasında tespit edilmiştir. Polar eksen uzunlukları 19,23-33,66 µm arasında, ekvatoral eksen çapları 14,95-28,61 µm olarak ölçülmüştür. Ornamentasyon polar bölge ve apertür çevresinde psilat, psilat-perforat, psilat-mikroretikülat ve mikroretikülat olarak saptanırken ekvatoral bölgede mikroretikülat olarak belirlenmiştir. Çalışma sonucunda polen şekli, polen büyüklüğü ve yüzey ornamentasyonu gibi karakterlerin türler arasında farklılık gösterdiği ve türlerin sistematik ayırımında taksonomik değere sahip olabilecek karakterler olduğu tespit edilmiştir.
