Özet:

This study aimed to fill data gaps (determination of available taxa and distribution) of the Cuscuta taxa, a holoparasitic genus, and are intended to define the environmental and socio-economic impacts in Turkey. For this, the evidence of Cuscuta taxa were obtained from studies, conducted on this genus in Turkey, and herbarium records of Turkey. Moreover, the impact types of taxa were examined, and the regional distribution of these taxa were detected based on grid system in Turkey. In addition, all records, in particular synonymous use, have been regulated taking into account the International Plant Name Index (IPNI), the Global Biodiversity Information Facility (GBIF) and The Plant List (PL). Considering the current arrangements and the newly identified records the presence of 23 Cuscuta taxa were identified in Turkey. In the impact assessments, apart from the parasitism in of all taxa, a total of six different impacts types have been detected that vary by taxa. These impact types are respectively as toxic (6 taxa), product quality (5), vector (3), structural (1), allelopathic (1) and ethnobotanic (1) impacts. The results can be used to mitigate the negative effects of Cuscuta taxa, and to develop the necessary precaution and control programs to preserve biodiversity, especially considering the infestation potential of parasitic plants. Moreover, the data obtained from this study, which is the first examination of all aspects of the impact types of Cuscuta taxa in Turkey, can provide a new direction and addition resource to the about parasitic plants studies, including awareness activities.
