- MakaleAçık Erişim2022Anatomical, Micromorphological, Karyological and Biochemical study of Scutellaria orientalis subsp. virens and Scutellaria salviifolia
Acar, Mikail; Tasar, Neslihan; Akbulut, Guelcin Beker
In this study, the anatomical and micromorphological structure, karyological characteristics and biochemical content of Scutellaria orientalis subsp. virens and endemic Scutellaria salviifolia, whose distributions areas overlap, were compared. Some anatomical and micromorphological differences were observed on the taxa; scleranchymatic pericycle layer on the stem, stomata density, distribution of trichomes, as well as the main vascular bundle and general shape of the petiole. The chromosome numbers of both taxa were determined as 2n = 22. However, there was a difference between chromosome length range and total chromosome length. The chromosome numbers and chromosome morphologies of these species have been defined for the first time in this paper. Differences in biochemical content were observed between species. Chlorophyll a (Chl a), total chlorophyll (Total Chl), total carbohydrate and malondialdehyde (MDA) contents were determined higher in leaf and stem samples of S. orientalis subsp. virens than S. salviifolia. There was no significant difference between the two taxa in terms of chlorophyll b (Chl b) content. Carotenoid (Car) content was detected higher in leaves samples of S. orientalis subsp. virens, but no significant difference was found between stems samples. Also, the effect of taxa on biochemical contents in relation to the habitat they live in is given in this study.

İncele - MakaleAçık Erişim2019Scopus SJRQ4MICROMORPHOLOGICAL AND ANATOMICAL INVESTIGATION ON SIX SPECIES OF ONOSMA L. (BORAGINACEAE) FROM TURKEY
Selvi, Selami; Polat, Ridvan; Babacan, Ebru Yuce; Rahman, M. Oliur; Çakilcioglu, Ugur
Micromorphology and anatomy of six Onosma L. species, viz. O. argentata Hub.Mor., O. neglecta Riedl, O. proballanthera Rech. f, O. rechingeri Riedl, O. sericea Willd. and O. stenoloba Hausskn. ex Riedl from Turky were investigated. Stem anatomy revealed that cuticle layer ranged from 0.6 mu m in O. argentata to 1.7 mu m in O. proballanthera. Parenchymatous cells of O. neglecta and O. stenoloba possessed more intense starch than the other species studied. In leaf anatomy, the longest palisade parenchyma was found in O. neglecta, while the smallest was noted in O. argentata. Mesophyll structure of O. argentata, O. sericea and O. rechingeri was equifacial (isobilateral), while O. neglecta, O. proballanthera and O. stenoloba presented bifacial (dorsiventral) structure. Rugose nutlet ornamentation was observed in O. argentata, O. neglecta and O. sericea, whereas reticulate type was found in O. proballanthera, O. rechingeri and O. stenoloba. Onosma stenoloba could easily be distinguished from other species by its aesterotrichous indumentum, and in contrary, other species possessed haplotrichous type of indumentum. Micromorphological features of nutlet surface, anatomical features of epidermal surface (trichomes and stomata), and lamina mesophyll structure (dorsiventral and isobilateral) could be useful in solving taxonomic problem of the genus.

Çakilcioglu, Ugur; Paksoy, Mehmet Y.; Babacan, Ebru Yuce; Polat, Ridvan
The micromorphological and anatomical characteristics of three species of Chrysochamela genus have been comparatively presented by using light microscopy (LM) and scanning electron microscopy (SEM). The micromorphological studies are related to the epidermal and seed surface. In anatomical studies, cross sections of the stems and leaves were examined and biometric measurement of cell and tissues were made. The stem and leaf anatomy of the genus were described. In addition, the stomatal index rate and stomatal index of these species were calculated. The leaf is dorsiventral in mesophyll-type. Except its C. noeana taxon, stellate trichomas are coincided in other taxon. Stoma can be observed on both sides of the leaf. Whereas stoma index rates of this genus were found in the range of 0.7 - 1.2, stoma types were observed as aniocytic and anomocytic. Seed surface of the genus can be found in reticulate, verrucae or in verrucaerugose types. In conclusion, the presence/absence of trichome over stem and leaves, the presence/absence of collenchyma in middle the vascular region, the seed shape, epidermal cell shape, and the characteristics of anticlinal boundaries and periclinal cell walls were found to be the important characters for identification of the Chrysochamela genus.

Paksoy, Mehmet Yavuz; Polat, Ridvan; Çakilcioglu, Ugur
Kundmannia Scop. is a genus of the Apiaceae (Umbelliferae) family which consists of 463 genera and ca. 3500 species. Kundmannia belongs to the Oenantheae tribe and are well represented in Spain, France, Italy, Turkey, Syria and North Africa where they grow on calcareous or siliceous soils. In this study; fruit micromorphology and the vegetative anatomy of the Kundmannia species growing in Turkey were compratively examined for the first time. The anatomical sections were taken from the stem, ray, leaf and and petiole of the plants for taxonomic deduction. Various tissues of taxa were given comparative micro anatomical measurements according to the anatomical studies, lignified or non-lignified medullary rays in stems, stomata types (diacytic and anomocytic), stomata index ratio (0.58 - 0.7), fruit shape and fruit epidermal surface are considered as important anatomical characters. In the fruit micromorphology, the cells on the mericarp surface have seen as striate and rugulate while the surface between the two ribs in the species have observed rugulate or striate. Fruit micromorphology and vegetative anatomy of the genus Kundmannia has not been studied before. However, the anatomical structure of the genus has been elucidated in this study, for the first time.

Polat, R.; Cakilcioglu, U.; Selvi, S.; Türkmen, Z.; Kandemir, A.
In this study, we comparatively investigated three endemic Salvia species spreading in Erzincan (Turkey) in terms of anatomy and micromorphology. For anatomical investigation, cross sections taken from stems and leaves of the species were examined under light microscope. For micromorphological investigation, epidermal surface and nutlet structure were examined using scanning electron microscopy. The S. euphratica and S. divaricata species were examined anatomically and micromorphologically for the first time, and S. hypargea was examined micromorphologically for the first time. In anatomical examinations, it was seen that stem and leaf structures of the species were similar. In micromorphological analyses, it has been seen that hairiness of the nutlet surface and nutlet ornamentations (verrucate and rugose type) created a difference between the species.
