英文摘要	Increasing aridity attributed to climate change is the main threat to the diversity and survival of Mediterranean forests including Tunisian pine species. The impact of this climatic condition in three pine species was examined in order to detect their responses to drought and guide their selection. Three Tunisian pine species: Pinus halepensis, Pinus brutia and Pinus canariensis growing in different climatic zones: humid, sub-humid, and semi-arid were studied in two months March and July 2016. Measurements carried out within this study are leaf gas exchange, twig water potential, and soil water content. The results showed a decrease in stomatal conductance and twig water potential in July in all pine species with increase in vapor pressure deficit and low soil water content. Pinus halepensis, P. canariensis and P. brutia had stronger stomatal control in semi-arid, sub-humid and humid climate, respectively (62, 95 and 63 mmol m(-2)S(-1)) and had higher stem water potential; for P. halepensis (-2.04 MPa) in semi-arid climate; for P. canariensis and P. brutia (-2.21, -2.39 MPa) in sub-humid and humid climate, respectively. Pinus halepensis, P. canariensis and P. brutia are better adapted to semi-arid, sub-humid and humid climates, respectively. Nevertheless, P. halepensis is considered the most resistant species as that could maintain higher photosynthesis, stomatal control and water use efficiency particularly in semi-arid climate. These findings help to assess the interaction between species and climate on the physiological response of pine species in mid-summer water deficit, and to select among these species the most resistant for future reforestation programs.
