The Effect of Combined Drought and Temperature Stress on the Physiological Status of Calcareous Grassland Species as Potential Candidates for Urban Green Infrastructure

Nature-based solutions are promising for climate adaptation and environmental management in urban areas, but conditions stressful vegetation. In particular, the interaction of drought high temperatures may be detrimental. Guiding plant selection greening with native species requires a far better knowledge adaptations stress acclimation. We tested physiological responses four candidate calcareous grassland green roofs walls to combined effects under controlled conditions. The proved relatively resistant despite different strategies protect photosynthetic apparatus, maintain water balance, repair damages. Based on responses, we rank descending order resistance factors tested: Trifolium medium > Festuca ovina Carex flacca Potentilla reptans, all can serve as potential candidates roofs. Physiological screening use supplements habitat template approach provide stronger wider base prioritizations.
