    The determination of the changes in epiphytic lichen diversity at microclimatic conditions the Quercus petraea (Mattuschka) Liebl. forest in the Uludag Mountains (Bursa, Turkey)
    (Gebruder Borntraeger, 2019-11-01) Öztürk, Sule; ÖZTÜRK, ŞULE; Güvenç, Şaban; GÜVENÇ, ŞABAN; Oran, Seyhan; ORAN, SEYHAN; 0000-0001-8724-9981; AAD-7322-2019; AAG-7065-2021; AAH-5039-2021
    The aim of this study is to determine the effects of microclimatic factors and tree size on epiphytic lichen diversity in different parts of Quercus petraea. The microclimatic factors used were tree size, the base and trunk of the tree. bark surface moisture, and environmental factors such as the amount of relative humidity and light in the environment. A total of 35 epiphytic lichen species was found in the Quercus petraea forest in the Uludag Mountains. Parmelia sulcata was the most common species. The highest species diversity was found in small trees. Shannon diversity on the trunk of the tree decreased with the increase in the tree size. The relationship between tree size and species richness on the trunk of the tree was found to be more significant than that found on the base. It has been determined that the frequency of some species on the base and trunk of the tree was increased as a result of an increase in the amount of relative humidity and light in the environment and an increase in the bark surface moisture. At the same time the frequency decreased when the amount of relative humidity and light in the environment and bark surface moisture decreased.

    Antifungal activity of evernia prunastri, parmelia sulcata , pseudevernia furfuracea var. Furfuracea
    (Pakistan Botanical Soc, 2015-08-01) Karabulut, Gözde; Öztürk, Şule; KARABULUT, GÖZDE; ÖZTÜRK, ŞULE; Uludağ Üniversitesi/Karacabey Meslek Yüksekokulu/Bitkisel ve Hayvancılık Bölümü/Organ Tarım Programı; 0000-0002-1284-7992; AAD-7322-2019; JCI-8505-2023
    The aim of this study was to investigate the In vitro efficacy of 96% alcohol extracts of Evernia prunastri and Pseudevernia fiirfitracea var. furfuracea that were in foliose-fruticose form and Parmelia sulcata in foliose form against important plant pathogens. The growth of fungal colonies in Petri plates amended with lichen extracts at 25 degrees C was measured a day before covering all surface of Petri plate in control treatment. Data were analysed according to statistic analysis test LSD at p <= 0.05. The in vitro efficacy of extracts of E. prunastri, P. sulcata and P. furfuracea var. furfuracea showed a significant inhibition against mycelia and spor growth of Aspergillits niger, Botrytis cinerea, Fusarium culmorum, F. solani, Macrophomina phaseolina, Penicillium expansum and Rhizoctonia solani. The level of inhibition among extracts showed variation. It was concluded that secondary metabolites of lichens may be used as biological chemicals against some plant pathogens.
