Opis:Global warming and increased frequency and/or severity of drought events are among the most threatening consequences of climate change for agricultural crops. Understanding the mechanisms of plant responses to both stressors is pivotal to successfully implement management strategies. Here we explored the effect of temperature on the development of grapevine leaves with particular focus on hydraulic traits under well-watered and water deficit conditions. We grew grafted grapevine (Vitis vinifera L. cv. Pinot noir) in two different greenhouse chambers (20/15°C vs 25/20°C day/night) and monitored their gas exchange, leaf size, stomatal density, chlorophyll fluorescence, pressure-volume (PV) curves, osmotic potential and petiole xylem anatomy. PV curves provided clear evidence that both, temperature and water availability, strongly affected the turgor loss point (TLP) as well as the connected physiological traits. Leaves developing at higher temperature exhibited a more conservative behaviour characterised by a lower gs max and a tighter stomatal closure in response to drought. The study further discusses the results considering the coordination of traits changing in tandem and implications in the face of climate change. Key message: The ambient temperature at which leaves develop impacts on its hydraulic traits and therefore on their successive response to drought
