Publication Additions to the lichen biota of the Kaz mountains (Çanakkale-Balıkesir, Turkey)(Blam E V, 2020-12-01) Oran, Seyhan; ORAN, SEYHAN; Bursa Uludağ Üniversitesi; 0000-0001-8196-2065; AAH-5039-2021In the present paper, 195 lichen taxa and one lichenicolous fungus are reported from the Kaz Mountains. Rhizocarpon jemtlandicum and Rinodina moziana are new to Turkey.Publication 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-5039-2021The 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.Publication Contributions to lichenized fungal diversity of Gorukle Vampus area (Bursa Uludag University-Bursa, Turkey)(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2019-01-01) Oran, Seyhan; ORAN, SEYHAN; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Biyoloji Bölümü.; AAH-5039-2021This investigation reports on 62 infrageneric taxa belonging to 38 genera from Bursa Uludag University Gorukle Campus Area. 43 of 62 taxa are new record for Gorukle Campus Area and 2 taxa are new for Bursa. A number of morphological, anatomical and ecological pecularities of the determined lichen taxa from the research area were evaluated. A great majority of the recorded lichen taxa were found as crustose and mesophytic form and low tolerance to eutrophication.Publication Effect of pollen sources on fruit set and quality of edible fig (Ficus carica L.) cv. 'Bursa siyahi'(Univ Agr Sci & Veterinary Med Cluj-napoca, 2022-01-01) ; AHI KOŞAR, DİLAN; KOŞAR, MEVLÜT BATUHAN; ORAN, SEYHAN; ERTÜRK, ÜMRAN; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; JCE-7775-2023; AAH-1653-2021; AAG-7343-2021The caprification practice has been used widely in fig cultivation because it affects the yield and quality of fig fruits, a phenomenon known as the 'xenia effect'. The present study was conducted to investigate the effects of pollen sources on fruit sets and fruit quality in the 'Bursa Siyahi' fig cultivar in 2017 and 2018. The eleven male genotypes and five cultivars were used as pollen source. The findings obtained in the present study showed that pollen sources significantly affected fruit set, early fruiting rate, fruit size, ostiole width, skin and flesh thickness, titratable acidity (TA), pH, and soluble solids content (SSC). The fruit set ratio varied from 32.02% ('16 03 06') to 76.66% ('16 08 07'), and fruit weight varied from 77.29 g ('16 03 06') to 106.88 g ('16 00 01') based on pollen sources. The ostiole diameter ranged from 3.84 mm ('16 ZF 08') to 7.67 mm ('77 00 01'). The skin thickness ranged from 3.01 mm ('Havran') to 5.35 mm ('16 00 01'). The principal component analysis was performed to distinguish the pollen sources for the 'Bursa Siyahi' cultivar. The analysis proposed that the most important factors affecting the fig quality can be reduced to five components. Fruit weight (0.958), skin thickness (0.810), flesh l* value (0.821), pH (-0.872), and SSC (0.836) value could be regarded as the characteristic indicators for PC1, PC2, PC3, PC4, and PC5, respectively. The results showed that '16 09 10', '16 05 03', '16 08 07', and '16 08 12' pollen sources are adequate pollinators for the edible 'Bursa Siyahi' Ig.
