Aegean climate compatible ornamental grass species and visual properties for landscape design
(Bursa Uludağ Üniversitesi, 2020-06-22) Wallace, Meltem Yağmur; Salman, Ali
Landscape architecture is a multidisciplinary branch based on the principle of conservation and / or re-creation of ecological balance. Landscape design is the fusion of both living and inanimate material based on this principle. The plant material, which is absolute for ecological balance, is classified hierarchically and used in the form of trees, shrubs, climbers, groundcovers, and grass groups. Within this structure, ornamental grasses constitute a group which is relatively new and infrequently used in Turkey. Ornamental grasses - the group of plants that develop mainly in ground covering or bushy form - are ecologically prominent, due to relatively low water consumption and design prominent, due to contribution to landscape colour and motion. In this research, 21 species and its 14 cultivars of 10 grass genera, Acorus gramineus ‘Ogon’ and ‘Variegatus’; Carex comans ‘Bronze’; Carex morrowii ‘Ice Dance’; Carex oshimensis ‘Everest’ and ‘Evergold’; Carex testacea; Cortaderia selloana ‘Gold Band’ and ‘Silverstar’; Leymus arenarius; Liriope muscari and L. muscari ‘Variegata’; Miscanthus sinensis ‘Flamingo’ and ‘Zebrinus’; Muhlenbergia capillaris; Ophiopogon japonicus and O. japonicus ‘Variegatus’; Pennisetum viridescens; Pennisetum setaceum ‘Rubrum’ and P. villosum with Stipa tenuissima, were observed over a four season period in Aegean climatic conditions; in this process, the plants’ adaptation to the area together with the visual changes they demonstrated were examined. As a result, among the grass group plants sold for the landscape sector in the Bayındır district of Izmir, the species which provided open field adaptation and avoided visual deterioration were determined. Therefore, a guiding source has been produced for compatible ornamental grass species and their visual characteristics which can be used in landscape designs in Aegean and Mediterranean climates. In this direction, it is aimed to spread the use of these grasses in order increase biodiversity and expand the visual richness of environmentally friendly landscape designs.

(Bursa Uludağ Üniversitesi, 2020-04-04) Karapınar, Hacer Sibel; Kılıçel, Fevzi
Aromatic plants are repositories of various elements in a wide concentration range with significant negative or positive health effects. It is known that there are more than twenty elements with physiological activity in mammals and humans. Elements like copper, nickel, cobalt and chromium are necessary ingredients of biological structures. Such elements may be toxic at concentrations above the limit values required for their function. In many biochemical reactions, elements such as lead, cadmium and arsenic have toxic effects. In this study, the amounts of some toxic elements in cumin and cinnamon samples were determined. Elemental amounts of Cr, Cd, Cu and Pb in 8 samples were analyzed with flame atomic absorption spectrometry (FAAS) method. According to the results, Cr element was found to be higher in the studied samples. Cu, Pb and Cd elements were found to be normal. In addition, the analytic method was confirmed by detection limits, accuracy, linearity and recovery experiments, sufficient values were obtained in each case.

(Bursa Uludağ Üniversitesi, 2020-06-19) Salman, Ali; Budak, Bülent; Wallace, Meltem Yağmur
The research was carried out in the experimental fields of Bayindir Vocational Training School at Ege University between the 2017-2018 vegetation periods. Five different commercial tulip varieties (Canadian Liberator, Van Eijk, Pink Impression, Carousel, Holland Beauty) were used as plant material. The research was carried out with three replications of randomized block design with two factors (cultivars, bio fertilizer application). In this study, first sprouting time, the beginning of flowering time, end of flowering time, flowering longevity, plant height, stem length and bulb yield values were examined. According to the data obtained from the research; the first sprouting occurred 49-72 days after planting date, the beginning of the flowering was in the range of the first week to the last week of March, and the end of flowering took place in the last week of March and mid-April. The flowering longevity was between 13 and 20 days, plant length was measured between 33.8 - 44.6 cm. Following to this stem length was measured and the value recorded between 27.3 - 36.2 cm. It was determined that the application of bio fertilizer increased bulb yield and did not reveal any impact on the other characteristics which was emphasized in this study.
Floristic properties of different commercial tulip varieties under the ecological conditions of Bayindir
(Bursa Uludağ Üniversitesi, 2020-06-22) Salman, Ali; Wallace, Meltem Yağmur
The research was carried out over a vegetation period at Ege University, Bayindir Vocational Training School’s trial fields between 2011 and 2012 to determine the adaptation performance of different commercial tulip cultivars under regional conditions. The research was carried out with three replications of randomized block design. Twenty different commercial tulip varieties of 10-12 sizes (Rai, Aladdin, Carnaval De Nice, Monte Carlo, Rem’s Favorite, White Triumphator, Pink Impression, Monesella, Oxford Elite, Cassini, Dow Jones, Van Eijk, Yokohama, Golden Apeldoorn, Ali Baba, Los Angeles, Rococco, Salmon Impression, Jan Van Nes, Wildhof) were evaluated in terms of sprouting time, flowering time, end of flowering time, flowering longevity, plant height and general bulb yield criteria. According to the data obtained, it was determined that there was a difference between varieties in terms of the characteristics examined. According to this; varieties of the first sprout time were observed at the earliest in January and at the latest in early March, the beginning of flowering was sighted earliest in March and latest in early April, while the end of flowering occurred between late March and late April. The duration of the flowering of the varieties ranged between 10 and 29 days and plant height differences were determined between 22.4 cm and 61.3 cm. In terms of bulb yield, cultivars except for Wildhof cultivar provided medium, good or very good bulb yield.
The relationship between planting design and urban identity
(Bursa Uludağ Üniversitesi, 2020-06-18) Zeybek, Osman; 0000-0002-2752-407X
Every city develops an identity according to its geography, nation, culture, and history which builds it. This identity is the main factor that shapes the collective memory of dwellers and visitors. It is an undeniable truth that plants which are used in squares, boulevards, and parks contribute a great value to collective memory. The material of this research consists of the books, dissertations, and articles written about planting design in urban identity and collective memory. Spaces that harmed or may harm in the future because of the changes in planting design have been examined and criticized. Besides the structural elements which create urban identity, plants are one of the main factors that affect the image of the city in the collective memory of people massively. The plants present in the open and green areas of the cities contribute to the formation of the identity of the city as much as the structures, and the protection of this vegetation also means protecting the identity of the city. To carry out research in the planting design and urban identity relationship line, 4 cases are selected. These cases express a unique example of plants’ existence and space’s identity; and it is registered that planting design contributes the protection of the space’s identity via collective memory; and makes people feel more attached to the place.
A research on designing plant sculptures in Turkey
(Bursa Uludağ Üniversitesi, 2020-06-19) Wallace, Meltem Yağmur; Salman, Ali; Yanmaz, Kemal; Budak, Bülent
Today, the increase of anthropological pressure on Earth dictates that design projects on landscape are more qualitative. Thus, with this scientific research, a new approach was offered on sculpturing, which is a valuable component of landscape design in an urban setting. The aim was to conceive ecologically sound and visually attractive spaces by creating sculptures with plants in place of traditional building materials such as stone and metal. The design process of the sculpture involved a variety of steps, resulting in the finished item being realised through living material. Hence, an iron frame for the sculpture was constructed in agreement with its threedimensional volume at the research fields of Ege University, Bayındır Vocational Training School. Following that, to keep the plant material alive, a geo-textile combined irrigation system was innovatively installed inside the frame and the outer side of the frame was donned with monofilament textile. The monofilament textile, filled with propagation material, helped to support the plants and create the realistic fleshy tissue of the sculpture. The sculpture, at its last stage, in accordance with the concept of the chosen figure, was clad with plant plugs that had high surface covering traits and a shallow root system. This research project can act as a source guide to encourage plant sculpture work in more ecological, visually distinguishable landscape design projects. Other significant outcomes of the research include rendering new usage to available materials, which will allow related industries to increase production and employment as well as decrease dependence on imports.

(Bursa Uludağ Üniversitesi, 2020-06-22) Zeybekoğlu, Emrah; Salman, Ali; Alp, Şevket; Ozzambak, M.Ercan; Wallace, Meltem Yağmur
The research was carried out over a vegetation period between December 2014 and June 2015 at Ege University, Bayindir Vocational School to investigate the floristic properties of different cool-climate narcissus varieties grown in pots under greenhouse conditions. Twenty-two different Narcissus cultivars (Professor Einstein, Tête-à-Tête, Carlton, Precocious, Furbelow, Ice Follies, Strong Gold, Dellan, Carbineer, Tamsyn, Actaea, Golden Harvest, Cheerfulness, Sempre Avanti, Scarlett O’Hara, Monal, Fortissimo, Pink Silk, White Lion, Fortune, Salome) were examined in terms of their floral quality in Mediterranean ecological conditions. For this purpose, different Narcissus cultivars were scrutinized through a set of visual criteria for their first flowering time, flowering duration, flower length, stem height and width together with the amount and diameter of their flowers. As a result, in accordance with each cultivar, rather different outcomes were demonstrated; the flowering times were within 48 and 79 days, the flower longevity was between 20 and 44 days. In addition, plant length 24.0 - 64.6 cm, stem lengths varied between 17.75 cm and 54.28 cm, stem diameters were within 0.70 cm and 1.35 cm. The largest flower diameter was measured at 12.1 cm and the highest number of florets counted was 3. All varieties used in the experiment were different from each other in terms of development speed, color, form and general appearance. It was concluded that all varieties used in the research could be evaluated as a potted ornamental plant.
