    Morphological, anatomical and ecological studies on Hyacinthella lineata (Liliaceae)
    (Ekoloji, 2008) Selvi, Selami; Erdoğan, Eyüp; Daşkın, Ruziye; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 15749906000
    In this study, the morphological characteristics of the species of Hyacinthella lineata (Liliaceae), which is an endemic species for Turkey; and the anatomical characteristics of its root, scape and leaf have been examined. In the morphological observations, the biometric mesaurements of the plant parts have been carried out. In the root anatomy, the pith region is comprised of metaxylem elements and in the cortex layer crystal sands have been encountered. In the scape anotomy, scleranchyma cells cover a wide part of area. The leaves are hypoamphistomatic and mesophylles are isolateral. As for, ecological studies, it was observed that this species generally prefers the soils which are clayed-loam-textured, neutral in terms of pH, rich in nitrogen, adequate phosphorus and potassium, slightly saline or nonsaline and show varying amounts of organic matter.

    Some evidence for infrageneric classification in Ziziphora L. (Lamiaceae:Mentheae)
    (Taylor & Franscis , 2015-03-04) Selvi, Selami; Martin, Esra; Satil, Fatih; Dirmenci, Tuncay; Sevcan, Çelenk; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 0000-0003-4925-8902; K-2981-2012; 24170598000
    The genus Ziziphora L. (Lamiaceae) consists of annual herbs, except Ziziphora clinopodioides, and is represented by six taxa in the flora of Turkey: Z. clinopodioides, Z. capitata, Z. persica, Z. tenuior, Z. taurica subsp. taurica and Z. taurica subsp. cleonioides. They are strong aromatic herbs and important medicinal plants. This study has been conducted to determine the palynological and karyological features of these taxa. The pollen morphology and exine structure of Ziziphora species were investigated by light microscope and scanning electron microscope. Pollen grains were determined as hexacolpate, medium in size and a circular or elliptic amb. The shape of pollen grains varies from oblate to prolate spheroidal. Ornamentation types of pollen grains are bireticulate, microreticulate or perforate. Somatic chromosome number has been determined and counted as 2n=16, 18. Results indicate that the pollen characters and chromosome numbers of the genus are valuable for taxonomic applications and may be useful for infrageneric classification.
