Allelopathic Potential of Macrofungi on Germinating Maize (Zea Mays L.) Grain
(Academic Journals, 2010) Uzun, Y.; Türker, M.; Kaya, A.; Demirel, K.; Işler, S.; Keleş, A.
The effect of methanol extracts of 10 macrofungi was evaluated on grain germination of maize (Zea mays L.). Germination percentage, radicle and plumule length and the level of carbohydrates and fatty acids were measured. Fungal metabolites inhibited germination up to 90.96%, plumule (97.77%) and radicle (92.83%) development. Plumule and radicle lengths were stimulated 35.26 and 10.60% in some assays, respectively. The fungal metabolites decreased the glucose (97.60%), sucrose (90.34%), fructose (96.85%), maltose (95.64%), oleic acid (97.50%) and linoleic acid (98.25%) levels, whereas increasing levels of the glucose (165.14%), sucrose (166.53%), fructose (83.18%), maltose (124.73%), oleic acid (6975.00%) and linoleic acid (5233.33%) were detected in some assays. It is concluded that macrofungi metabolites have commonly inhibitory effects on physiological and morphological processes of germinating maize grain except for considerable increases in the some parameters investigated. © 2010 Academic Journals.
Contributions To the Macrofungi Flora of Gümüşhane Province
(2006) Uzun, Y.; Keleş, A.; Demirel, K.
Some macrofungi specimens were collected from Gümüşhane province between 2001 and 2003. As a result of field and laboratory studies, 105 taxa belonging to 2 classes and 24 families were identified. These taxa are presented in a list. Of the 105 taxa, 14 are new records for the mycoflora of Turkey. © TÜBİTAK.
Macrofungal Diversity of Erzincan Province (Turkey)
(Asian Network for Scientific Information, 2010) Keleş, A.; Demirel, K.
The present study was carried out on macrofungi collected from Erzincan province between 2006 and 2007. The macroscopic and ecological features of macrofungi were recorded in field. The specimens were taken to laboratory. The microscopic data and the identification of macrofungi were carried out in the laboratory using related literature and mycological techniques. According to the field and laboratory investigations 191 taxa belonging to 33 families and nine orders in Pezizomycetes and Agaricomycetes classis were determined. All of the taxa are new to the province. Nine taxa are determined as new records for Turkish mycobiota. The new records are Helvella latispora Boud., Conocybe pubescens (Gillet) Kühner, Coprinus strossmayeri Schulz. Coprinus vosoustii Pilát, Leccinum atrostipitatum A.H. Sm. Thiers and Watl., Entoloma poliopus var. parvisporigerum Noordel., Psathyrella friesii Kits v Wav., Russula dryadicola Fellner and Landa and Russula silvicola Shaff. © 2010 Asian Network for Scientific Information.
Macromycetes of Genç District (bingöl-Turkey)
(2009) Uzun, Y.; Kaya, A.; Keleş, A.; Akçay, M.E.; Acar, I.
The study was conducted on the macrofungi specimens collected from Genç district (Bingöl-Turkey) between 2006-2009 to determine the macromycota of the region. Seventy eight taxa belonging to 23 families in Ascomycetes and Basidiomycetes classes were identified. Agaricaceae, Tricholomataceae and Strophariaceae are the most crowded families in the region. All of the taxa are new for the district. Omphalotus olivascens var. olivascens (Marasmiaceae) is determined as new record for Turkish macromycota. © 2009 Asian Network for Scientific Information.
