Abstract

Türkiye’de yetişen gövdeyi saran yapraklı Potamogeton L. türleri P. praelongus Wulfen ve P. perfoliatus L.’tur. Bugüne kadar bu türlerin dağılımı, habitat tercihleri ve anatomik özellikleriyle ilgili detaylı çalışmalar yoktur. Potamogeton perfoliatus ülke çapında yaygın bir türdür ancak P. praelongus sadece bir lokaliteden kaydedilmiştir. Bu nedenle P. praelongus Türkiye’de nadir ve tehdit altındadır. Bu çalışmada 86 herbaryum örneğine dayanarak P. perfoliatus’u 54 sulak alandan kaydettik. Türlerin yetiştiği suların fiziksel ve kimyasal parametreleri P. perfoliatus için 24 noktadan, P. praelongus için bir noktadan ölçülmüştür. Bulgularımıza göre, P. praelongus oligotrofik, kalkerli ve alkali alpin bir gölde yetişmektedir. Potamogeton perfoliatus çok farklı habitatlarda bulunmakla birlikte, yüksek pH, düşük tuzluluk değerlerine sahip, derin ve durgun suları tercih etmektedir. Türlerin gövde anatomileri P. praelongus için 3 birey, P. perfoliatus için ise 35 bireyden örnek alınarak incelenmiştir. Türlerin morfolojik özellikleri de araştırılmış ve Türkiye’den toplanan materyallere dayalı olarak betimler hazırlanmıştır. Türler arasındaki ayırt edici anatomik ve morfolojik karakterler verilmiştir. Anatomi bulgularımız P. praelongus’un önceki bazı çalışmalara aykırı olarak sekiz iletim demetine sahip olduğunu göstermektedir. Bu çalışmada türlerin güncel dağılım ve habitat tercihleriyle ilgili sunduğumuz kapsamlı bulgular iki batık Potamogeton türünün gelecekte izlenmesinde faydalı olacaktır.

HABITAT PREFERENCES, DISTRIBUTION AND ANATOMY OF THE CLASPING-LEAVED PONDWEEDS OF TURKEY

Abstract

Clasping-leaved Potamogeton L. species growing in Turkey are P. praelongus Wulfen and P. perfoliatus L. There exists no detailed study about distribution, habitat requirements, and anatomical properties of the Turkish populations of the two species. Potamogeton perfoliatus is widespread throughout the country but P. praelongus was recorded only from a single locality. Therefore, P. praelongus is rare and endangered in Turkey. In this study, we recorded presence of P. perfoliatus in 54 wetlands based on examination of 86 herbarium specimens. Physical and chemical parameters of the water bodies where the two species occur were measured from 24 sites for P. perfoliatus and from one site for P. praelongus. According to our findings, P. praelongus grows in an alpine lake with oligotrophic, calcareous and alkaline water. Potamogeton perfoliatus occupies diverse habitats but prefers deep lentic water bodies with high pH and low salinity levels. Stem anatomy of the species were studied based on three individuals for P. praelongus and 35 individuals for P. perfoliatus. Morphological features of the species were also investigated and descriptions based on Turkish material were prepared. We provided the distinguishing anatomical and morphological characters between the species. Our anatomical findings showed that P. praelongus specimens have eight vascular bundles in contrast to previous reports on the species. Our results can be used for future monitoring of the two submerged Potamogeton species as we provide detailed information about their current distribution pattern and habitat features.
