Publication An evaluation of toxic properties of woody landscape plants used in hospital garden design(Sage Publications Inc, 2023-10-09) SEYİDOĞLU AKDENİZ, NİLÜFER; Akdeniz, Nilufer Seyidoğlu; ZENCİRKIRAN, MURAT; Zencırkıran, Murat; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; AAH-1676-2021; AAH-1574-2021Objectives: In this study, it was aimed to evaluate the landscape plants used in the design of hospital gardens in terms of toxicity. Background: Although plants have positive effects on humans, some plants can be toxic due to the compounds found in their bodies. The toxicity of plants is an issue that needs to be addressed in design, and it is important to investigate the toxic properties of plants in designs to be made in hospital gardens, which have a large user population and especially where people come to heal. Methods: Observation technique and document analysis were used in the study. Species were identified by taking samples from landscape plants in the gardens of state hospitals in Bursa. The distribution of the identified plant taxa according to toxic groups and their relations with each other were analyzed. Results: Taxa used in hospital gardens were mostly nontoxic (54.43%). It has been determined that there is a linear relationship between the number of taxa and toxic groups, and the increase in the number of taxa also increases the number of toxic taxa. Conclusion: It is seen that toxic plants are used in the design of hospital gardens, but they are included in toxic taxa. It will be an important approach to raise awareness by placing labels showing the toxicity status of taxa together with the collection of toxic taxa at points far from users.Publication A research on the soil characteristics and woody plant species of urban boulevards in Bursa, Turkey(Tarbiat Modares Univ, 2019-01-01) Akdeniz, N. Seyidoğlu; SEYİDOĞLU AKDENİZ, NİLÜFER; TÜMSAVAŞ, ZEYNAL; Zencırkıran, M.; ZENCİRKIRAN, MURAT; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; AAH-1676-2021; AAH-1574-2021Proper planning and design of transportation networks in the cities is an important subject, and the avenues, boulevards and refuges in the cities give the cities an aesthetic and functional feature as open green spaces. In addition to their aesthetic qualities, planting in urban areas also plays an important role in preventing pollution and improving air quality in the cities. In this context, the existing woody plant taxa were identified on the boulevards located in Nilufer district of Bursa in Turkey. The soil characteristics and soil heavy metal accumulations of these woody plant taxa were also determined. In the studied boulevards, there were 34 genera, 31 species, 10 subspecies and varieties belonging to 23 families. Among the total woody species gathered, 72.73% of the woody species were tree species and the rest were shrubs. The soils found on the boulevards were usually sandy and clay loam, and inadequate in terms of organic matter contents. On the other hand, the heavy metal deposits in the territories of the boulevards situated in the industrial zones were higher than those in other housing areas but below the permissible values.
