    Anatomical, Micromorphological, Karyological and Biochemical study of Scutellaria orientalis subsp. virens and Scutellaria salviifolia
    (2022) AÇAR, MIKAIL; TASAR, NESLIHAN; AKBULUT, Gülçin 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.

    Anatomical, Palynological and Biochemical Studies on Gundelia dersim Vitek, Yüce & Ergin(Asteraceae) an Endemic of Turkey
    (2021) AÇAR, Mikail; AKBULUT, Gülçin BEKER; TASAR, NESLIHAN
    The Asteraceae family is the largest in the plant kingdom in the world. Gundelia is agenus that belongs to this family and is commonly referred to as the kenger name in Anatolia. Gundeliadersim is also an endemic species defined from Eastern Anatolia. In this study, anatomical,palynological and biochemical properties of G. dersim were discussed. When the anatomical structureof G. dersim was examined, it was seen that the mesophyll type, in which the midrib of the leaf wasdeveloped, was unifacial. There are too many sclerenchymatic cells in the vascular bundles. In addition,laticifer elements were seen on the stem and leaf. Also, it was observed that the pollen of the species isin echinate ornamentation and pollen grains are radial symmetrical, isopolar, tricolporate. Followingbiochemical analysis, pigment analysis, total carbohydrate and lipid peroxidation were performed. Thechlorophyll a and chlorophyll b content of the species in both stem and leaf were analyzed, and the mostchlorophyll content was found in the leaf. With this research, for the first time, a detailed anatomicalinvestigation was conducted on the genus Gundelia, and it is a current view with the first considerationof the anatomical, palynological and biochemical aspects of G. dersim.
