Türkiye Vincetoxicum Cinsinin Vejetatif Kısımlarının Taramalı Elektron Mikroskobu İle İncelenmesi

Vincetoxicum, Türkiye’de üçü endemik (V. coskuncelebiana S.Makbul & S.Güven, V. fuscatum (Hornem.) subsp. boissieri (Kusn.) Browicz ve V. parviflorum Decne) olmak üzere dokuz türe ait 11 takson ile temsil edilmektedir. Bu çalışmada, tüm Türkiye Vincetoxicum taksonlarının gövde, petiyol ve lamina mikro-morfolojisi taramalı elektron mikroskobu (SEM) kullanılarak ilk kez taksonomik yönden değerlendirilmiştir. Mikro-morfolojik incelemeler, farklı habitatlardan toplanan 21 populasyona ait herbaryum örnekleri üzerinde gerçekleştirilmiştir. İncelenen her takson için SEM fotoğraflarıyla desteklenen ayrıntılı birer gövde, petiyol ve lamina mikro-morfolojik betimi oluşturulmuştur. Türkiye Vincetoxicum taksonlarının ayrımında; gövde, petiyol ve lamina yüzeylerindeki tüylenme çeşidi, tüy dağılımı ve yoğunluğu ile yaprağın her iki yüzeyindeki stoma durumu gibi mikromorfolojik karakterlerin önemli rol oynadığı belirlenmiştir. Diğer taraftan, incelenen taksonlar arasında gövde, yaprak sapı ve lamina üzerindeki epikütikular mumun görünümü, epidermis hücrelerinin şekli ve içbükeylik/dışbükeylik özellikleri bakımından bir fark görülmemiştir.

A Scanning Electron Microscope Study of Vegetative Parts of the Genus Vincetoxicum in Türkiye

Abstract

In Türkiye, Vincetoxicum is represented by 11 taxa belonging to nine species, three of which (V. coskuncelebiana S.Makbul & S.Güven, V. fuscatum (Hornem.) subsp. boissieri (Kusn.) Browicz, and V. parviflorum Decne) are endemics. In this study, the micro-morphology of the stem, petiole, and lamina of all Turkish Vincetoxicum taxa was examined using a scanning electron microscope (SEM) for the first time. Micro-morphological observations were carried out on herbarium samples belonging to 21 populations from various habitats. A detailed micro-morphological description of the stem, petiole, and lamina, supported by SEM micrographs, was created for each examined taxon. It was determined that the micro-morphological characteristics such as the pattern of pubescence, the distribution and density of trichomes on the stem, petiole, and lamina, and the position of stomata on both sides of the leaf contributed to the distinction of the Turkish Vincetoxicum taxa. On the other hand, no difference was observed among the examined taxa in terms of the appearance of epicuticular wax, and shape and concavity/convexity properties of epidermal cells on stem, petiole, and lamina.
