In recent years, the cultivation and consumption of tropical fruits in Türkiye have gained increasing prominence, driven by global climate change, rising input costs in greenhouse vegetable production, and the expanding commercial value of tropical fruit species. Among these, passionfruit (Passiflora edulis) has emerged as a particularly attractive crop due to its relatively low labor requirements, capacity to bear fruit twice annually, and potential use as a living fence. Despite the general perception of global warming as a rise in average temperatures, low winter temperatures remain a critical constraint on the cultivation of tropical fruit crops. This study was conducted to assess the impact of low temperatures on open-field cultivation of passionfruit under the ecological conditions of Manavgat, Türkiye, between May 2021 and June 2025. Evaluations included plant growth, flowering dynamics, the effects of low winter temperatures, and post-frost recovery performance. In the first winter following planting, minimum temperatures of 0.3, 0.7, 0.6, and 0.7 °C were recorded on January 2022, 20, 24, 25, and 26 respectively, leading to prolonged frost events. In contrast, no sub-3.0 °C temperatures were recorded in 2023 and 2024, while a single minimum of 2.2 °C occurred in 2025. Flowering was observed twice per year, in June and October. The results demonstrate that open-field cultivation of passionfruit is feasible under the ecological conditions of Manavgat. Nevertheless, to mitigate frost-related risks and extend the flowering period, further investigations into passionfruit production under protected cultivation systems are strongly recommended.
