In this study, seeds of 5 species of Acanthophyllum in Turkey were examined with stereomicroscope and scanning electron microscope (SEM) to evaluate the systematic significance of seed microstructure. The seeds of Acanthophyllum were characterised by oblong or obovate shape. Seeds dorsal and ventral side are generally convex. The largest seeds are found in A. acerosum (2.45 mm in length and 1.16 mm in width). The smallest seeds are found in A. verticillatum (1.61 mm in length and 0.84 mm in width). Seeds surface of Acanthophyllum species are fine tuberculate arranged with elongate or polygonal cells like jigsaw puzzle. The shape of suture is sinuous, undulate or dentate. The colour of seed is reddish-brown or yellowish-brown. The radicle is on the one side of each seed and just out beyond the hilar notch. Colour of seeds, seed length and width, hilum length and width, suture shape, testa cell shape and the number of suture points per plate are important characters in differentiating Acanthophyllum species. By this study, similarities and differences between the species of Acanthophyllum genus are revealed and contributed to taxonomic studies.Keywords: Caryophyllaceae, Acanthophyllum, Micromorphology, Seed, Scanning Electron Microscope (SEM) Türkiye Acanthophyllum C.A.Mey. (Caryophyllaceae) cinsi tohum morfolojisi Özet: Bu çalışmada Türkiye Acanthophyllum cinsine ait 5 türün tohum mikroyapısı sistematik önemini değerlendirmek için stereomikroskop ve taramalı elektron mikroskopu (SEM) ile incelenmiştir. Acanthophyllum tohumları oblong veya obovat şekli ile karakterizedir. Tohum dorsal ve ventral yüzeyleri genellikle konvekstir. En büyük tohumlar A. acerosum'da bulunur (2.45 mm uzunluğunda ve 1.16 mm genişliğindedir). En küçük tohumlar A. verticillatum'da bulunur (1.61 mm uzunluğunda ve 0.84 mm genişliğindedir). Acanthophyllum türlerinin tohumları, yapboz gibi uzun veya çokgen hücrelerle düzenlenmiş ince tüberküllüdür. Sütur şekli sinuous, undulate veya dentattır. Tohum rengi kırmızımsı kahverengi veya sarımsı kahverengidir. Radikula yalnızca bir tarafta ve hilum açıklığından daha ileride sonlanmaktadır. Tohum rengi, tohum uzunluğu ve genişliği, hilum uzunluğu ve genişliği, sütur şekli, testa hücrelerinin şekli sütur başına gözlenen diş sayısı Acanthophyllum türlerini ayırmada önemli karakterlerdir. Bu çalışmada, Acanthophyllum cinsi arasındaki benzerlikler ve farklılıklar ortaya çıkarılmış ve taksonomik araştırmalara katkıda bulunulmuştur.
The aim of the present work is to provide an account on the morphological features of pollen of Veronica species in Turkey, as a contribution to future research. Pollen morphology of 20 species of the Veronica were investigated using Light Microscope (LM) and Scanning Electron Microscope (SEM). Different palyno-morphological features including; pollen ornamentation, colpus ornamentation, size of polar and equatorial diameter, P/E ratio, exine thickness, and size of colpus were observed. The study revealed that the pollen grains of the studied Veronica species were in all cases tricolpate, radially symmetrical and isopolar, oblate-spheroidal or prolate spheroidal. The surface pattern of the exine varied from striato-reticulate and striato-microreticulate to microechinate-perforate, which allows recognition of three homonymous types of pollen grains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
