    Anatomical and nutlet differentiation between Teucrium montanum and T. polium from Turkey
    (DE GRUYTER OPEN LTD, 2011) Dinc, Muhittin; Dogu, Suleyman; Koca, Asli Dogru; Kaya, Basturk
    Teucrium montanum L. and T. polium L. are the two closest Teucrium L. species from sect. Polium (Mill.) Schreb in Turkey. In addition, they are sympatric for some part of their range in Turkey. In this study, comparative anatomical and micromorphological studies of the two species are carried out. They have been investigated by their leaf and stem anatomical features, as well as nutlet micromorphological characteristics. The results of anatomical studies show that the anatomical characters of both taxa are observed to be similar to the general features of the family Lamiaceae anatomy, except for lacking rich collenchyma at the corners. Both taxa are similar in stem anatomy and their leaves exhibit xeromorphy. However, trichome morphology on the stems and the leaves appear to have a taxonomic value in segregation of the two taxa. Light and scanning electron microscope studies on the nutlets also show that nutlet shapes, measures and surface micromorphologies are different in the two species. Whereas nutlet surfaces are bireticulate in both species, the nutlets are larger and primary sculpturing is more distinct in T. polium than in T. montanum. Moreover, the nutlets are oblong to oblong-ovoid and larger in T. polium, but ovoid and smaller in T. montanum.

    (AGRIMEDIA GMBH, 2017) Danton, Ombeline; Özcan, Mehmet Musa; Figueredo, Gilles; Chalard, Pierre; Dogu, Suleyman; Uslu, Nurhan; Chalchat, Jean Claude
    Chemical compositions of O.majorana, O. onites and O. saccatum oils were determined by GC and GC-MS. The yields of the essential oils were 0.276%, 0.395% and 0.261% v/w, respectively. The most abundant compounds of O.majorana, O. onites and O.saccatum oils were a-terpinene, p-cymene, gamma-terpinene and carvacrol. The highest carvacrol (10.920%) and linalool (10.271%) were found in O. onites oil. in addition, while myrcene is found as 10.471% and 4.817% in O. majorana and O. onites oils, respectively. Myrcene was determined as 0.662% in O.saccatum. The key component of Oregano species tested is p-cymene. The contents of p-cymene in O.majorana, O. onites and O. soccatum oils were determined as 33.416%, 17.417% and 73.143%, respectively. Also, gamma-terpinene contents of oil samples ranged from 17.798% (O. saccatum) to 29.932% (O. majorana).

    (ASSOC PHARMACEUTICAL TEACHERS INDIA, 2017) Bagci, Yavuz; Kan, Yuksel; Dogu, Suleyman; Celik, Sadiye Ayse
    Purpose: In this study, essential oil (EO) compositions of the dried and fresh aerial parts of Origanum majorana cultivated in the research field and collected from f from Mersin was investigated. Material and Methods: EO was distilled by using Clevenger type apparatus for 3 h and the chemical compositions were detected in GC-MS. While, the oil yields of the the collected marjoram was determined to be 2,5 ml both in dried and fresh aerial parts, the yields of the cultivated plants for fresh and dried parts were 3.6 ml and 5 ml, respectively. The cultivation of the plant had positive effects on the EO yield. Drying of the material also increased the oil yield in the cultivated marjoram. Results: While there were 42 and 35 of EO components were observed in the fresh and dried parts of the collected marjoram, respectively; in the cultivated plants there were 30 and 40 components detected. Besides EO yields, in this research the differences with respect to composition and components were determined between the cultivated and collected plants. On the other hand, in this study, it was determined that the EO compositions varied with respect to be fresh or dry of the plant parts. It was observed that carvacrol and linalool were the major EO contents. Conclusion: The aim of the study to compare of differences between the EO compounds and compositions varied according to be the plant fresh or dry and collected or cultivated.

    The Essential Oil Compositions of Rosmarinus officinalis L. Cultivated in Konya and Collected from Mersin-Turkey
    (ASSOC PHARMACEUTICAL TEACHERS INDIA, 2017) Bagci, Yavuz; Kan, Yuksel; Dogu, Suleyman; Celik, Sadiye Ayse
    Purpose: In this research, essential oil (EO) compositions of the dried and fresh aerial parts of Rosmarinus officinalis cultivated in the reearch field in Selcuk University Medicinal and Aromatic Plants Department Area in Konya and collected from Mersin was investigated. Material and Methods: EO was distilled by using Clevenger type apparatus for 3 h and the chemical compositions were detected in GC-MS. Results: Although, the oil yields of the collected rosemary was determined to be 0.4 ml (in fresh) and 0.6 ml (in dried) aerial parts, the yields of the cultivated plants for fresh and dried parts were 0.32 ml (in fresh) and 0.9 ml (in dried), respectively. In this research the differences with respect to composition and components were determined between the cultivated and collected plants. On the other hand, in this study, it was also determined that the EO compositions varied with respect to be fresh or dry of the plant parts. While there were 67 and 55 of EO compositions were observed in the fresh and dried parts of the collected marjoram, respectively; in the cultivated plants there were 46 (in fresh) and 79 (in dried) components detected. Conclusion: In this study, it was observed that the major EO compositions were camphor, 1.8-cineole, borneol, a-pinene, linalool, verbenone, bornyl acetate, limonene and camphene. The objective of the study to detect the differences between the EO compositions varied according to be the plant fresh or dry and collected or cultivated.

    MORPHOLOGICAL IDENTIFICATION OF VESICULAR-ARBUSCULAR MYCORRHIZA ON BULBOUS PLANTS (TAURUS MOUNTAIN IN TURKEY)
    (INST BIOLOSKA ISTRAZIVANJA SINISA STANKOVIC, 2015) Karaarslan, Emel; Uyanoz, Refik; Dogu, Suleyman
    This study was conducted to investigate the morphological identification of vesicular-arbuscular mycorrhiza (VAM) on bulbous plants in the Taurus Mountains in Turkey. Thirteen soil samples and bulbous roots were taken from the rhizosphere of bulbous plants. The soils were analyzed for the number of VAM spores and chemical and physical properties. In addition, the roots were examined for infection levels, and morphological identification of VAM spores was made. All tested plants are considered mycorrhizal plants. We determined three spore species (Glomus mosseae, Glomus hoi and Scutellospora calospora) from the surveyed soils. The spore distribution rates were as follows: G. Mossea 61.54 %, G. Hoi 23.07 % and Scutellospora calospora 15.38 %. Results suggest that VAM fungal spores and root colonization display variation in rhizosphere under bulbous plants in different ecological conditions.

    Taxonomic reinstatement of Teucrium andrusi from T-paederotoides based on morphological and anatomical evidences
    (WILEY-BLACKWELL, 2011) Dinc, Muhittin; Dogu, Suleyman; Bagci, Yavuz
    Teucrium andrusi, described by Post from Mardin province, Turkey, was synonimized with T. paederotoides in the flora of Turkey. According to the records in the flora of Turkey T. paederotoides was a steno-endemic species, only known from the type locality in Gaziantep and from Mardin province. Specimens of T. paederotoides s.l. were collected from both localities and a detailed comparison of the plants from Gaziantep with those from Mardin revealed that the two populations were sufficiently distinct from each other to be recognised as separate species. Thus, T. andrusi Post is reinstated from the synonymy with T. paederotoides. Teucrium andrusi is morphologically different from T. paederotoides s.s. in terms of its general indumentum, leaf margin, bract and calyx shape, corolla colour and nutlet macro-micromorphology. It can be anatomically distinguished from T. paederotoides s.s. by stoma type, stomatal distribution on the leaf surface, crystal content in the cells and cuticula thickness. Ecological data related with the accompanying species also support species status for T. andrusi. While the two taxa are very similar in pollen and nutlet morphology, trichome density on the nutlets are different.
