    THE CONTRIBUTION OF URBAN ROAD TREES ON IMPROVING THE AIR QUALITY IN AN URBAN AREA
    (Parlar Scientific Publications (P S P), 2015) Ozturk, Sevgi; Bozdogan, Elif
    Landscape plantings in avenues, boulevards, and medians play a prominent role in the construction of outdoor green areas, and contribute both aesthetically and functionally. Roadside planting requires ecological, biological, aesthetic, and technical knowledge and is considered to be multidirectional. One of the most significant functions of roadside planting is the improvement of air quality caused by decreasing atmospheric pollution. Within this scope, the purpose of this study was to determine the metal accumulation of the roadside plants in Kastamonu city, Turkey. Metal accumulation was measured in 80 individual leaves belonging to 18 species inhabiting a 10.5 kilometer-long route in Kastamonu. Results showed that, between the measured elements, zinc (Zn) was accumulated at the highest levels, followed by copper (Cu), lead (Pb), nickel (Ni), and cadmium (Cd), in the given order. Highest Zn, Cd, and Cu levels were detected in Betula pendula, Elaeagnus angustifolia, Catalpa bignonioides, respectively, and the highest Ni and Pb levels were found in Acer campestre. These species are frequently used in urban green areas due to their aesthetic characteristics and their ability to accumulate heavy metals and improving the air quality. We suggest that these plants may be useful for monitoring air pollution.

    DETERMINATION OF THE PERCEIVED QUALITY OF URBAN LIFE IN NEW AND TRADITIONAL HOUSING TEXTURES
    (Parlar Scientific Publications (P S P), 2014) Ozturk, Sevgi; Bozdogan, Elif
    In this study, the perceived life quality of individuals residing in the Kastamonu districts of Hepkebirler, where traditional texture is concentrated, and Inonu, one of the new settlement regions, were assessed on the basis of the issues of architecture and urban planning (7 scales), open and green areas (8 scales), and reinforcement components (12 scales). The study determined that the district of Inonu had a higher level of perceived life quality than the district of Hepkebirler for all criteria, excluding ease of transportation to the city centre and public areas, with respect to architecture and urban planning. This was also true for all criteria with respect to outdoor green area reinforcements, except lighting units, waste bins, and food and beverage units. It was also determined that perceived urban life quality was high in both settlements with respect to ease of transportation and, at the lowest level, sufficiency of parking space. This study can be the basis for a model for determining the perceived life quality of medium-sized cities in Turkey.

    Morphological characterization of Cyclamen sp grown naturally in Turkey: Part I
    (Elsevier, 2015) Curuk, Pembe; Sogut, Zerrin; Bozdogan, Elif; Izgu, Tolga; Sevindik, Basar; Tagipur, Ehsan Mohammad; Teixeira da Silva, Jaime A.
    Twenty cyclamen taxa belonging to the Primulaceae originate from the Mediterranean region and grow under trees and bushes. There are 10 cyclamen species growing naturally in Turkey, five of which are endemic. In this study, intact cyclamen plants were collected from nature with their tubers intact Collection took place in spring and autumn in Adana, Osmaniye, Kahramanmaras, Izmir and Eskisehir provinces, 50 samples per location. Sampled plants were propagated and cultivated in Adana. The morphology of four Cyclamen species (C. persicum Mill., C. cilicium Boiss.e.Heldr., C. pseudibericum Hildebr. and C. coum Mill.) was characterized using 1-year-old regenerated plants. A total of 27 phenotypic characters (13 flower, 11 leaf, 2 plant, 1 tuber) were evaluated based on a detailed descriptor's list. In addition to these morphological observations, 13 quantitative traits (7 flower, 5 leaf, 1 tuber) were measured. The measurements related to morphological characteristics had a wide range of variation, including in tuber diameter, leaf length and width, petal length, petal color, and leaf shape, indicating the vast morphological differences among these four cyclamen species. In most cases, the use of principal component analysis confirmed the gfouping of characters into species-specific clusters although one or two clusters could not differentiate species, indicating that morphological and cluster analyses alone are not enough for characterizing this complex Cyclamen germplasm and that molecular techniques may reveal more intricate and useful relationships.
