|a Climate change would increase frequency and intensity of extreme events as heat and cold waves. There is a lack of studies that consider the co-occurrence of these waves with other abiotic factors relevant on a climate change scenario as salinity. Therefore, it could be interesting to improve our knowledge about the effects that this co-occurrence could have in different species due to the species specific effect of the photosynthesis tolerance to extreme temperatures. A controlled condition experiment was performed using the salt marsh species Sarcocornia perrnis with eight experimental blocks combining temperature ranges (40-28/22-15/13-5 °C) and salinity concentration on the growth solution (171/1050 mM NaCl). After 3 days of treatment, gas exchange, chlorophyll a fluorescence, pigment profile and water state measurement were applied. Photosynthetic machinery function of this perennial species decreased on for both high and low temperature range. Nevertheless, at 13-5 °C the effect of the salinity was mainly due to diffusion limitations more than to damage on the photosystems. At 40-28 °C, in presence of optimal salinity S. fruticosa was not altered overall. However, high temperatures in combination with high salinity reduced the photosynthetic capacity mainly by reducing the efficiency of the electron transport chain
