    Antimicrobial activity of the resins obtained from the roots and stems of Cedrus libani and Abies cilicica.
    (2002) Kizil M.; Kizil G.; Yavuz M.; Aytekin C.
    The antimicrobial activity of the ethanol extract of resins obtained from the roots and stems of Cedrus libani and Abies cilicica was investigated using a disc diffusion method. Results revealed that crude extracts of the resins of both plants are highly effective against tested microorganisms by preventing their growth to a greater extent.

    Forage yield and lodging traits in peas (Pisum sativum L.) with different leaf types
    (2010) Bilgili U.; Uzun A.; Sincik M.; Yavuz M.; Aydinoğlu B.; Çakmakci S.; Geren H.
    Two semi-leafless and four leafed pea (Pisum sativum L.) genotypes were evaluated for plant height, lodging scores, and forage yield in eight diverse locations with typical Mediterranean or Mediterranean-type climate in the 2001-2002 and 2002-2003 growing seasons. The genotypes used in this study were forage type with indeterminate growing habit. Significant differences among pea genotypes were found for all traits over years and locations. All interactions which related to G × E interaction showed significance (P>0.01) for all traits. The forage yield of the pea genotypes averaged 26605 kg ha-1 and the highest yield was obtained from the leafed genotype Urunlu. Its forage yield reached to 35970 kg ha-1 yield level at Samsun location.

    Trace metal determination in the medicinal plant hyoscyamus (solanaceae) by inductively coupled plasma optical emission spectrometry
    (Perkin - Elmer Corp., 2014) Keskin C.; Kisin E.; Yavuz M.
    The concentrations of Cd, Ni, Cu, Pb, Cr, Fe, B, and A1 were determined in four different medicinal plants of the Hyoscyamus species: Hyoscyamus reticulums L, Hyoscyamus leptocalyx STAPF, Hyoscyamus aureus L, and Hyoscyamus albus L by ICP-OES. By considering the sensitivity of ICP-OES with respect to the trace level determination of Cd, Ni, Cu, Pb, Cr, Fe, B, and Al in the studied plant samples and the limitations of sample amount possible in a microwave digestion procedure, the ashing method was applied before analysis and proved the quantitative measurements of the elements.The accuracy of the method was verified by comparison to the certified reference sample NCSZC 73014 Tea Leaves. The RSD values were between 0.14-10.4%, while the error values were in the 90-107% range. The results show that with the proposed method higher concentrations of Ni, Cr, Pb, Fe, and B were determined in H. aureus. Interestingly, the concentration of Cu in H. reticulatus was approximately 48.5 times higher than the mean Cu values of the other three Hyoscyamus species, while the Pb concentration levels in H. aureus were 17.8 times higher than in the H. reticulatus L, H. leptocalyx STAPF, and H. albus L species.
