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.
Analysis of Trace Metal Levels in Wild Mushrooms
(Asian Journal of Chemistry, 2011) Kaya, A.; Genccelep, H.; Uzun, Y.; Demirel, K.
Three macro elements and nine trace elements contents of 30 wild edible mushrooms collected from Kahramanmaras province of Turkey, were analyzed. The minimum and maximum heavy metal amounts of mushrooms were analyzed as mg/g dry weight for Ca (0.072-8.32), Mg (0.33-6.56), K (8.11-28.15) and as mg/kg for Fe (65.56-7156), Zn (13.18-230.85), Cu (4.30-84.67), Cr (0.77-80.03), Mn (5.15-91.21), Pb (not detected-3.10), Ni (0.79-174.15), Cd (0.00-8.67) and Co (0.00-10.92). The potassium content was found to be higher than those of the other minerals in all mushrooms, studied and Morchella deliciosa was found to have the highest Fe, Cr, Mn, Pb, Ni and Co concentrations among the analyzed species.

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.
