Palynological Investigation of Some Trifolium L. (Fabaceae) Species Distributed in Şanlıurfa

Öz

In this study, the pollen morphology of 5 species (Trifolium boissieri Guss. ex-Soy. -Will. & Godr., T. dasyurum C.Presl, T. pauciflorum d'Urv., T. scabrum L., and T. spumosum L.) belonging to the genus Trifolium L. from the Fabaceae family, distributed in Şanlıurfa province, was examined with light and electron microscopes. Within the framework of the palynological study, pollen shapes, ornamentations, pore and colpus lengths and widths were determined and their measurements were given. Pollen grains are generally monad in structure, have trizonocolporate aperture, and subprolate to prolate-spheroidal shape. Ornamentation generally shows significant differences in polar and equatorial regions. In the pollen grains examined, perforate, psilate-perforate, and reticulate ornamentation is seen in the polar region, while microreticulate and reticulate ornamentation is dominant in the equatorial region. While the polar axis lengths were determined to be between 38.67-29.19 μm on average, the equatorial axis length was determined to be between 33.79-23.45 μm on average. As a result of the study, it was determined that characters such as pollen shape, pollen size, and surface ornamentation differed among species and these were the characters that could have taxonomic value in the systematic distinction of species.

Şanlıurfa’da Yayılış Gösteren Bazı Trifolium L. (Fabaceae) Türlerinin Palinolojik Yönden İncelenmesi

Öz

Bu çalışmada, Şanlıurfa ilinde yayılış gösteren Fabaceae familyasından Trifolium L. cinsine ait 5 türün (Trifolium boissieri Guss. ex Soy.-Will. & Godr., T. dasyurum C.Presl, T. pauciflorum d'Urv., T. scabrum L., T. spumosum L.,) polen morfolojisi ışık ve elektron mikroskopları ile incelenmiştir. Palinolojik çalışma çerçevesinde polen şekilleri, polen yüzey ornamentasyonları, por ve kolpus uzunlukları ve genişlikleri tespit edilmiş ve ölçümleri verilmiştir. Polenler genel monad yapıda, trizonokolporat apertüre sahip ve subprolat ile prolat-sferoidal şekle sahiptir. Ornamentasyon ise genellikle polar ve ekvatoral bölgede belirgin farklılıklar göstermektedir. İncelenen polenlerde polar bölgede perforat, psilat-perforat ve retükalat ornamentasyon görülürken Ekvatoral bölgede ise mikroretikülat ve retikülat ornamentasyon baskındır. Polar eksen uzunlukları ortalama 38,67- 29,19 μm arasında tespit edilirken ekvatoral eksen uzunluğu ise ortalama 33,79- 23,45 μm arasında tespit edilmiştir. Polen şekli, polen büyüklüğü ve yüzey ornamentasyon gibi karakterlerin türler arasında farklılık gösterdiği ve türlerin sistematik ayrımında taksonomik değere sahip karakterler olduğu tespit edilmiştir.
