Özet
Roses have always attracted people's attention with their aesthetic and aromatic properties, scents and colorsthroughout the historical process. The microclimatic conditions created by the Euphrates caused the Halfeti Rose(Rosa x odorata 'Louis XIV'), a hybrid rose species brought to the region many years ago, to acquire its almostblack color and scent and to become the production area of this heritage. In addition, as a result of its adaptationto the region, 'Black Rose' received a geographical indication in 2021 in order to contribute to rural tourism andthe rural population to turn to different business areas. Halfeti Roses bloom twice a year and take their darkestcolor when they turn into buds in autumn. If suitable ecological conditions are provided, there are also roses thatretain their black color after fully blooming. For example, it has been determined that the chlorophyll content oftaxa commonly used in the region such as Halfeti rose, Chinese rose and oil rose, Muhammedi rose are higherthan taxa brought from different ecologies such as Van and Gümüşhane. Rose fruits are generally classified aswaste and it is stated that the effective use of these waste products is limited. In this context, it is also importantto examine the fruit characteristics of Halfeti Roses. Compared with the fruits of Halfeti Rose and other taxa, theaverage values in pomological parameters except vitamin C; it was determined that the number of nuclei waslow. In addition, it has been found that the physiological characteristics of Halfeti Rose have lower stomataldensity, higher chlorophyll content and average leaf proportional water content values compared to other taxa.At the same time, the fatty acid values in the seeds were average. Adaptation of the plant to Şanlıurfa ecology interms of physiological characteristics, dark petal color in this ecology, long flowering time and a habitus withmedium growth strength are the main features that can contribute to the spread of Halfeti Rose. In this study, theeffective factors in Halfeti Rose's black color and the results of research on its different characteristics wereexamined.Keywords: Rosa x odorata, Halfeti Rose, Ecology, Rosa L.
