Veronica L. (Plantaginaceae) cinsine ait bazı taksonlarin polen morfolojileri ve onun sistematik önemi

Abstract

Bu çalışmada Plantaginacae familyasından Veronica L. (Plantaginaceae) cinsine ait V. bozakmanii M. A. Fisch., V. triphyllos L., V. persica Poir., V.triloba Opiz., V. anagallis-aquatica L., V. oxycarpa Boiss., V.cinerea Boiss. & Balansa, V. macrostachya Vahl. subsp. mardinensis (Bornm.) M. A. Fisch., V. orientalis L. subsp. orientalis, V. orientalis L. subsp. nimrodi (Richt. ex Stapf) M. A. Fisch. taksonlarının palinolojik özellikleri açısından incelenmiştir. Bu taksonlara ait örnekler yapılan arazi çalışmalarında toplanmıştır. Bu cinse ait taksonlar LM ve SEM kullanılarak incelenmiştir. Bu çalışma sonucunda polen tektat, polen şekillerinin subprolat prolat olması ve simetrinin heteropolar olması gibi bazı özellikler bulunmuştur. Ayrıca apertür gibi trikolpat SEM mikrofotoğrafları da ormentasyon yapılarının retikulat, skabrat-perforat ve striat-mikroretikulat olduğunu göstermiştir.

Abstract

In this study, the genus Veronica L. (Plantaginaceae) from the Plantaginacae family V. bozakmanii M.A.Fisch., V. triphyllos L., V. persica Poir., V.triloba Opiz., V. anagallis-aquatica L., V. oxycarpa Boiss., V. cinerea Boiss. & Balansa., V. macrostachya Vahl. subsp. mardinensis (Bornm.) M. A. Fisch., V. orientalis L. subsp. orientalis, V. orientalis L. subsp. nimrodi (Richt. ex Stapf) M.A. Fisch taxa were investigated in terms of palynological features. The specimens of this taxa were collected during the field surveys were investigated using Light Microscope (LM) and Scanning Electron Microscope (SEM). As a result of this study some common traits of the taxa found out such as polen tectate, the pollen shapes being subprolate, prolate and the symmetry being heteropolar. Also, the type of the aperture is tricolpate. The SEM microphotographs shows that the ornamentations are reticulate, scabrate-perforate and striate-microreticulate.
