Establishing determining the visual quality and its gegenerative production in order to generalizefor generalizing the usage of Sorbus domestica L. in the sample city, Bartin

This dissertation offers to practitioners some information about how Sorbus domestica L.is grown by using generative methods, determination of importance in Landscape Architecture, and how and where this plant can be used as a composition in Landscape Design. As a result of using intensively exotic species rahter than native species, plant diversity remains only in rural landscape. Giving importance to exotic species has brought about the degeneration in urban landscape. Even though our country is rather rich in terms of having plant material, the uniformity is quite common problem because of using more than enough allien species. Therefore, the arrangement of plant sellection is very important in city centre. İn this study, it is shown that how compatable plants can be obtained on account of aesthetic and ecological aspects by considering eligible cost. Generative method has been preferred as a technique due to high cost and requiring much material for steel production. The work which is the subject of a natural type of Western Black Sea Sorbus domestica L. were collected from trees that are grown in nature environment. After keeping the seeds for 4 months in cold athmosphere, it has been planted in 4 different environments with 3 different experimental models. İt can be said that yhe highest germination took place in turf at %82, in turf-river sand at %77, and in forest soil at %45 respectively. In the second phase of the study, 6 different places were chosen as green spaces in the city center of Bartin in order to apply design criteria such as diversity, harmony, contrast, balance and emphasis. For each of the selected field of studies were seperately evaluated considering usage of native and exotic species. With the help of simulation studies which were applied to chosen areas with natural and exotic species, the awareness of the citizens for natural species were tried to be determined by survey. According to the survey, although the citizens have seen the natural species in rural environment, they ignore the allien species and want to see the natural species around it.
