Endemik bitkiler sahip oldukları nadir bulunma özelliklerinin yanı sıra estetik özellikleri ile peyzaj mimarlığı çalışmaları için önemli bitki grubunu oluşturmaktadır. Bitkilerin sahip oldukları estetik özellikler ve bitkilendirme çalışmalarında ortaya koydukları değer ile tasarımın ekolojik boyutu olan bitkilerin yaşadıkları ortamda uygun olmayan çevre koşullarına uyum sağlayarak gösterdikleri tolerans doğrudan ilişkilidir. Düzce’de bulunan ve Karadeniz Bölgesi için endemik bir tür olan Seseli resinosum Freyn & Sint. (Batı Karadeniz horozgözü) ve yalnızca Düzce ili sınırları içerinde yayılış gösteren Cephalaria duzceënsis N. Aksoy & R. S. Göktürk (Düzce pelemir otu) bitkilerinin kullanıldığı bu çalışmanın amacı, her iki türün peyzaj mimarlığında kullanımlarını estetik, fonksiyonel ve ekolojik potansiyelleri açısından belirlemektir. Bu amaç doğrultusunda, bitkilerin mevsimsel değişim potansiyelleri, yayılış gösterdikleri habitatlar düzeyinde bir yıl boyunca incelenmiştir. Bitkilerin yaprak, çiçek, sürgün, meyve gibi estetik özelliklerinin yanı sıra yaşam ortamlarındaki sosyobilite, yayılış, yaşam formu gibi bitki sosyolojisi özellikleri de incelenmiştir. Ayrıca, bitkilerin verimini önemli ölçüde sınırlayan iki önemli abiyotik stres olan kuraklık ve tuzluluk altında yaprak boy, yaş ve kuru ağırlığı gibi büyüme parametrelerindeki değişimler de ortaya konulmuştur. Sonuç olarak, bitkilerin peyzaj mimarlığında kullanım potansiyelleri her iki bitkinin ekolojik koşullarının kentsel adaptasyon özellikleri de dikkate alınarak oluşturulmuştur. Her iki endemik türün de çiçek estetikleri ön plana çıkarken Seseli resinosum sahip olduğu herdem yeşil yaprak yapısı ile bitki kompozisyonlarındaki renk sürekliliğine katkı sunmaktadır. Ayrıca, kuraklık ve tuz stresi koşullarına karşı iki endemik türün de biyokütlesinde değişim belirlenmiş olup S. resinosum’un tuz, C. duzceënsis’in ise kuraklık stresine toleransının yüksek olduğu belirlenmiştir.
Endemic plants form an important group of plants for landscape architecture studies, as well as their rare presence properties as well as their aesthetic properties. The aesthetic characteristics and the value they show in planting studies are directly related to the ecological dimension of the design and the tolerance they show by adapting to the environmental conditions that are not appropriate in the environment in which they live. Located in Düzce and is an endemic species for the Black Sea Region, Sound Resinosum Freyn & Sint. Cephalaria duzceënsis N. Aksoy & R. S. (Western Black Sea Horoscope) and only spread within the borders of the Flat Sea. The aim of this study, in which the plants are used, is to determine the use of both species in the landscape architecture in terms of their aesthetic, functional and ecological potential. For this purpose, the potential for seasonal change of plants has been studied for a year at the level of habitats in which they spread. In addition to the aesthetic characteristics of plants such as leaves, flowers, decay, fruits, as well as the sociality, spread, and life forms in their living environments have also been studied. Furthermore, changes in growth parameters such as leaf length, age and dry weight under dryness and saltness, which are two major abiotic stress that significantly limit the productivity of plants, have also been revealed. As a result, the potential for use in the landscape architecture of plants is created taking into account the urban adaptation characteristics of both plants’ ecological conditions. Both endemic species are also leading the flowering aesthetics to the forefront while the sound resinosum contributes to the continuity of color in the plant compositions with the herd green leaf structure. In addition, two endemic species against dry and salt stress conditions have also been determined by changes in their biomass and S. resinosum has a high tolerance to salt and C. duzceënsis to dry stress.
Endemic plants constitute an important plant group for landscape architecture studies with their aesthetic features as well as their rarity. The aesthetic characteristics of plants and their value in planting studies are directly related to the tolerance of plants, the ecological dimension of the design, by adapting to unsuitable environmental conditions. The purpose of this study is to explore the usability of Seseli resinosum Freyn & Sint., an endemic species in the Western Black Sea Region, and Cephalaria duzceënsis N. Aksoy & R. S. Göktürk, distributing only in Düzce, in landscape architecture in terms of their aesthetic, functional and ecological potentials. The seasonal change potential of plants was examined for one year at the level of habitats. Besides the aesthetic characteristics of plants such as leaves, flowers, stem and fruit, plant sociology features in their living environments were examined such as sociability, distribution and life form. Furthermore, we measured the changes in growth parameters such as leaf length, fresh and dry weight under drought and salinity, two important abiotic stresses that significantly limit the yield of plants. As a result, the potential usability of both endemic plants in landscape architecture were determined regarding their adaptation capabilities to the urban ecological conditions. Seseli resinosum contributes to the color continuity in plant compositions with its evergreen leaf structure, while both of the endemic species have flower aesthetic value. Moreover, drought and salt stresses lead to changes in biomass of both endemics and it has been determined that S. resinosum had higher salt tolerance, while C. duzceënsis had greater drought tolerance.
