    Germination Physiology and Autecology of Centaurea Kilaea Boiss. From Turkey
    (Penerbit Universiti Kebangsaan Malaysia, 2013) Eskin, B.; Özyiğit, İbrahim İlker; Doğan, İlhan; Altay, V.; Demir, G.; Serin, M.
    In this study germination requirements, plant-soil interactions and population biology of Centaurea kilaea was studied. The plant and soil samples were collected from Sofular Village (Sile District) and shore of Çatalca District (Istanbul) in Turkey by using standard methods. Methods like Scheibler, Wetdigestion, Kjeldahl and Olsen were employed for measurement of soil texture, structure and other physical and chemical characteristics (pH, total protein and electrical conductivity) using spectrophotometer, flame photometer, calcimeter and ICP. The results showed that ranges of different elements in the soil were 0.007-0.2% for N, 0.0007-0.001% for P, 0.001-0.01% for K, 0.0001-0.0002 % for Na. N, P, K and Na values in the plants were 2.17, 0.005, 0.1 and 0.006%, respectively. The data revealed that germination success of the seeds was influenced by the environmental factors such as pH, germination season and temperature.

    Distribution of Some Elements in Veronica Scutellata L. From Bolu, Turkey: Soil-Plant Interactions
    (Penerbit Universiti Kebangsaan Malaysia, 2013) Özyiğit, İbrahim İlker; Doğan, İlhan; Demir, G.; Eskin, B.; Keskin, M.; Yalçın, İbrahim Ertuğrul
    Veronica scutellata L. occurs in moist and wet habitats, such as ponds, marshes and other wetlands. This study was conducted on this species to examine its mineral element uptake status in terms of interactions between soil and plant. Experimental materials were taken from the Southern coast of Black Sea at coordinates 40°36'N and 31°16'E at an altitude of 1400 m above sea level from Bolu - Turkey; using standard methods and plant (root, stem and leaf parts) and soil mineral element measurements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, Ni and Zn) were done. During the study, ICP-OES was employed for the measurement of mineral elements. It was observed that considerable amounts of B, Ca, K, Mg, Mn, Na and Zn are accumulated by the plant.
