    Ecological-social-economical impacts of vertical gardens in the sustainable city model
    (Centenary University, 2016) Başdoğan, Gülçinay; Çiğ, Arzu
    Issues such as utilization of natural resources, environmental problems and global climate change increase the awareness on “green design” in the built environment and give direction to the attempts of creating cities with natural environment. In this context, planting works are done on the facades of the buildings to reduce the negative impacts of urbanization and create a sustainable city model. These practices are called vertical gardens- living walls- green facades. Vertical gardens, which allow growth of various species of plants in the complicated city life, balance urban ecology and enhance the quality of urban life. Strengthening the urban ecosystem and improvement of economic-social balances constitute the essence of a sustainable city model. Vertical garden practices contribute to increasing air quality, reduction of urban heat island affect, increasing energy efficiency, reduction of noise pollution in addition to reduction of stress caused by the urban life by improving city aesthetic and provide new job opportunities in the economy. In this study, it is aimed to determine ecological-economical-social impacts of vertical gardens to create liveable, ideal and healthy environments and to reveal how they contribute to sustainable urban model. © 2016, Centenary University.

    Effects of treatments of gibberellic acid, citric acid and stratification on germination of seeds of Salvia siirtica Kahraman, Celep & Dogan sp. nov. (Lamiaceae)
    (Nobel Science and Research Center, 2017) Arslan, Dogan; Çiğ, Arzu; Arslan, Hüseyin; Bayraktar, Önder Volkan; Tülücü, Faruk
    Salvia siirtica Kahraman, Celep & Dogan sp. nov. (Lamiaceae) have been recently reported as a new species from southeaster Turkey. It is currently grown in remote areas, where locally adapted and sparsely populated. The study will be of paramount importance for understanding of germination behavior in Salvia siirtica, possibly due to encouraging its propagation, but not being endangered. For this reason, conducted a study, consisting of a set of germination tests, under the tissue culture laboratory. In this study, Salvia siirtica seeds were treated with gibberellic acid (24 h and 48 h in GA3 of 250 mg l-1), citric acid (5 and 10 min in its solution of 4 %) and stratification (14 and 28 day in fine sand maintaining in refrigerator of + 4 °C). Experiment was set up in completely randomized factorial design with three replications. Comparing with control, sole gibberellic acid treatment or combined with other treatments had no effect on Salvia siirtica germination and rooting behavior. But, combined effects of citric acid and stratification treatments were statistically significant (p < 0.01). The highest germination and rooting rates (21.25 and 17.97 %, respectively) were measured on stratification treatment of 28 day.
